The Header and Footer + parameters for DynamicPatternLayout must be syntactically in the form of a PatternString, + but should not be marked as type log4net.Util.PatternString. Doing so causes the + pattern to be statically converted at configuration time and causes DynamicPatternLayout + to perform the same as PatternLayout. + Please see for complete documentation. + + <layout type="log4net.Layout.DynamicPatternLayout"> + <param name="Header" value="%newline**** Trace Opened Local: %date{yyyy-MM-dd HH:mm:ss.fff} UTC: %utcdate{yyyy-MM-dd HH:mm:ss.fff} ****%newline" /> + <param name="Footer" value="**** Trace Closed %date{yyyy-MM-dd HH:mm:ss.fff} ****%newline" /> + </layout> + + + + + + A flexible layout configurable with pattern string. + + + + The goal of this class is to a + as a string. The results + depend on the conversion pattern. + + + The conversion pattern is closely related to the conversion + pattern of the printf function in C. A conversion pattern is + composed of literal text and format control expressions called + conversion specifiers. + + + You are free to insert any literal text within the conversion + pattern. + + + Each conversion specifier starts with a percent sign (%) and is + followed by optional format modifiers and a conversion + pattern name. The conversion pattern name specifies the type of + data, e.g. logger, level, date, thread name. The format + modifiers control such things as field width, padding, left and + right justification. The following is a simple example. + + + Let the conversion pattern be "%-5level [%thread]: %message%newline" and assume + that the log4net environment was set to use a PatternLayout. Then the + statements + + + ILog log = LogManager.GetLogger(typeof(TestApp)); + log.Debug("Message 1"); + log.Warn("Message 2"); + + would yield the output + + DEBUG [main]: Message 1 + WARN [main]: Message 2 + + + Note that there is no explicit separator between text and + conversion specifiers. The pattern parser knows when it has reached + the end of a conversion specifier when it reads a conversion + character. In the example above the conversion specifier + %-5level means the level of the logging event should be left + justified to a width of five characters. + + + The recognized conversion pattern names are: + + + + Conversion Pattern Name + Effect + + + a + Equivalent to appdomain + + + appdomain + + Used to output the friendly name of the AppDomain where the + logging event was generated. + + + + aspnet-cache + + + Used to output all cache items in the case of %aspnet-cache or just one named item if used as %aspnet-cache{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-context + + + Used to output all context items in the case of %aspnet-context or just one named item if used as %aspnet-context{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-request + + + Used to output all request parameters in the case of %aspnet-request or just one named param if used as %aspnet-request{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-session + + + Used to output all session items in the case of %aspnet-session or just one named item if used as %aspnet-session{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + c + Equivalent to logger + + + C + Equivalent to type + + + class + Equivalent to type + + + d + Equivalent to date + + + date + + + Used to output the date of the logging event in the local time zone. + To output the date in universal time use the %utcdate pattern. + The date conversion + specifier may be followed by a date format specifier enclosed + between braces.

However, + with the aid of format modifiers it is possible to change the + minimum field width, the maximum field width and justification. + + + The optional format modifier is placed between the percent sign + and the conversion pattern name. + + + The first optional format modifier is the left justification + flag which is just the minus (-) character. Then comes the + optional minimum field width modifier. This is a decimal + constant that represents the minimum number of characters to + output. If the data item requires fewer characters, it is padded on + either the left or the right until the minimum width is + reached. The default is to pad on the left (right justify) but you + can specify right padding with the left justification flag. The + padding character is space. If the data item is larger than the + minimum field width, the field is expanded to accommodate the + data. The value is never truncated. + + + This behavior can be changed using the maximum field + width modifier which is designated by a period followed by a + decimal constant. If the data item is longer than the maximum + field, then the extra characters are removed from the + beginning of the data item and not from the end. For + example, it the maximum field width is eight and the data item is + ten characters long, then the first two characters of the data item + are dropped.

+ + Note about caller location information.
+ The following patterns %type %file %line %method %location %class %C %F %L %l %M + all generate caller location information. + Location information uses the System.Diagnostics.StackTrace class to generate + a call stack. The caller's information is then extracted from this stack. +
+ + + The System.Diagnostics.StackTrace class is not supported on the + .NET Compact Framework 1.0 therefore caller location information is not + available on that framework. + + + + + The System.Diagnostics.StackTrace class has this to say about Release builds: + + + "StackTrace information will be most informative with Debug build configurations. + By default, Debug builds include debug symbols, while Release builds do not. The + debug symbols contain most of the file, method name, line number, and column + information used in constructing StackFrame and StackTrace objects. StackTrace + might not report as many method calls as expected, due to code transformations + that occur during optimization." + + + This means that in a Release build the caller information may be incomplete or may + not exist at all! Therefore caller location information cannot be relied upon in a Release build. + + + + Additional pattern converters may be registered with a specific + instance using the method. + +

The Header and Footer + parameters for DynamicPatternLayout must be syntactically in the form of a PatternString, + but should not be marked as type log4net.Util.PatternString. Doing so causes the + pattern to be statically converted at configuration time and causes DynamicPatternLayout + to perform the same as PatternLayout. + Please see for complete documentation. + + <layout type="log4net.Layout.DynamicPatternLayout"> + <param name="Header" value="%newline**** Trace Opened Local: %date{yyyy-MM-dd HH:mm:ss.fff} UTC: %utcdate{yyyy-MM-dd HH:mm:ss.fff} ****%newline" /> + <param name="Footer" value="**** Trace Closed %date{yyyy-MM-dd HH:mm:ss.fff} ****%newline" /> + </layout> + + + + + + A flexible layout configurable with pattern string. + + + + The goal of this class is to a + as a string. The results + depend on the conversion pattern. + + + The conversion pattern is closely related to the conversion + pattern of the printf function in C. A conversion pattern is + composed of literal text and format control expressions called + conversion specifiers. + + + You are free to insert any literal text within the conversion + pattern. + + + Each conversion specifier starts with a percent sign (%) and is + followed by optional format modifiers and a conversion + pattern name. The conversion pattern name specifies the type of + data, e.g. logger, level, date, thread name. The format + modifiers control such things as field width, padding, left and + right justification. The following is a simple example. + + + Let the conversion pattern be "%-5level [%thread]: %message%newline" and assume + that the log4net environment was set to use a PatternLayout. Then the + statements + + + ILog log = LogManager.GetLogger(typeof(TestApp)); + log.Debug("Message 1"); + log.Warn("Message 2"); + + would yield the output + + DEBUG [main]: Message 1 + WARN [main]: Message 2 + + + Note that there is no explicit separator between text and + conversion specifiers. The pattern parser knows when it has reached + the end of a conversion specifier when it reads a conversion + character. In the example above the conversion specifier + %-5level means the level of the logging event should be left + justified to a width of five characters. + + + The recognized conversion pattern names are: + + + + Conversion Pattern Name + Effect + + + a + Equivalent to appdomain + + + appdomain + + Used to output the friendly name of the AppDomain where the + logging event was generated. + + + + aspnet-cache + + + Used to output all cache items in the case of %aspnet-cache or just one named item if used as %aspnet-cache{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-context + + + Used to output all context items in the case of %aspnet-context or just one named item if used as %aspnet-context{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-request + + + Used to output all request parameters in the case of %aspnet-request or just one named param if used as %aspnet-request{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-session + + + Used to output all session items in the case of %aspnet-session or just one named item if used as %aspnet-session{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + c + Equivalent to logger + + + C + Equivalent to type + + + class + Equivalent to type + + + d + Equivalent to date + + + date + + + Used to output the date of the logging event in the local time zone. + To output the date in universal time use the %utcdate pattern. + The date conversion + specifier may be followed by a date format specifier enclosed + between braces.

However, + with the aid of format modifiers it is possible to change the + minimum field width, the maximum field width and justification. + + + The optional format modifier is placed between the percent sign + and the conversion pattern name. + + + The first optional format modifier is the left justification + flag which is just the minus (-) character. Then comes the + optional minimum field width modifier. This is a decimal + constant that represents the minimum number of characters to + output. If the data item requires fewer characters, it is padded on + either the left or the right until the minimum width is + reached. The default is to pad on the left (right justify) but you + can specify right padding with the left justification flag. The + padding character is space. If the data item is larger than the + minimum field width, the field is expanded to accommodate the + data. The value is never truncated. + + + This behavior can be changed using the maximum field + width modifier which is designated by a period followed by a + decimal constant. If the data item is longer than the maximum + field, then the extra characters are removed from the + beginning of the data item and not from the end. For + example, it the maximum field width is eight and the data item is + ten characters long, then the first two characters of the data item + are dropped.

+ + Note about caller location information.
+ The following patterns %type %file %line %method %location %class %C %F %L %l %M + all generate caller location information. + Location information uses the System.Diagnostics.StackTrace class to generate + a call stack. The caller's information is then extracted from this stack. +
+ + + The System.Diagnostics.StackTrace class is not supported on the + .NET Compact Framework 1.0 therefore caller location information is not + available on that framework. + + + + + The System.Diagnostics.StackTrace class has this to say about Release builds: + + + "StackTrace information will be most informative with Debug build configurations. + By default, Debug builds include debug symbols, while Release builds do not. The + debug symbols contain most of the file, method name, line number, and column + information used in constructing StackFrame and StackTrace objects. StackTrace + might not report as many method calls as expected, due to code transformations + that occur during optimization." + + + This means that in a Release build the caller information may be incomplete or may + not exist at all! Therefore caller location information cannot be relied upon in a Release build. + + + + Additional pattern converters may be registered with a specific + instance using the method. + +

The Header and Footer + parameters for DynamicPatternLayout must be syntactically in the form of a PatternString, + but should not be marked as type log4net.Util.PatternString. Doing so causes the + pattern to be statically converted at configuration time and causes DynamicPatternLayout + to perform the same as PatternLayout. + Please see for complete documentation. + + <layout type="log4net.Layout.DynamicPatternLayout"> + <param name="Header" value="%newline**** Trace Opened Local: %date{yyyy-MM-dd HH:mm:ss.fff} UTC: %utcdate{yyyy-MM-dd HH:mm:ss.fff} ****%newline" /> + <param name="Footer" value="**** Trace Closed %date{yyyy-MM-dd HH:mm:ss.fff} ****%newline" /> + </layout> + + + + + + A flexible layout configurable with pattern string. + + + + The goal of this class is to a + as a string. The results + depend on the conversion pattern. + + + The conversion pattern is closely related to the conversion + pattern of the printf function in C. A conversion pattern is + composed of literal text and format control expressions called + conversion specifiers. + + + You are free to insert any literal text within the conversion + pattern. + + + Each conversion specifier starts with a percent sign (%) and is + followed by optional format modifiers and a conversion + pattern name. The conversion pattern name specifies the type of + data, e.g. logger, level, date, thread name. The format + modifiers control such things as field width, padding, left and + right justification. The following is a simple example. + + + Let the conversion pattern be "%-5level [%thread]: %message%newline" and assume + that the log4net environment was set to use a PatternLayout. Then the + statements + + + ILog log = LogManager.GetLogger(typeof(TestApp)); + log.Debug("Message 1"); + log.Warn("Message 2"); + + would yield the output + + DEBUG [main]: Message 1 + WARN [main]: Message 2 + + + Note that there is no explicit separator between text and + conversion specifiers. The pattern parser knows when it has reached + the end of a conversion specifier when it reads a conversion + character. In the example above the conversion specifier + %-5level means the level of the logging event should be left + justified to a width of five characters. + + + The recognized conversion pattern names are: + + + + Conversion Pattern Name + Effect + + + a + Equivalent to appdomain + + + appdomain + + Used to output the friendly name of the AppDomain where the + logging event was generated. + + + + aspnet-cache + + + Used to output all cache items in the case of %aspnet-cache or just one named item if used as %aspnet-cache{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-context + + + Used to output all context items in the case of %aspnet-context or just one named item if used as %aspnet-context{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-request + + + Used to output all request parameters in the case of %aspnet-request or just one named param if used as %aspnet-request{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-session + + + Used to output all session items in the case of %aspnet-session or just one named item if used as %aspnet-session{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + c + Equivalent to logger + + + C + Equivalent to type + + + class + Equivalent to type + + + d + Equivalent to date + + + date + + + Used to output the date of the logging event in the local time zone. + To output the date in universal time use the %utcdate pattern. + The date conversion + specifier may be followed by a date format specifier enclosed + between braces.

+ + Note about caller location information.
+ The following patterns %type %file %line %method %location %class %C %F %L %l %M + all generate caller location information. + Location information uses the System.Diagnostics.StackTrace class to generate + a call stack. The caller's information is then extracted from this stack. +
+ + + The System.Diagnostics.StackTrace class is not supported on the + .NET Compact Framework 1.0 therefore caller location information is not + available on that framework. + + + + + The System.Diagnostics.StackTrace class has this to say about Release builds: + + + "StackTrace information will be most informative with Debug build configurations. + By default, Debug builds include debug symbols, while Release builds do not. The + debug symbols contain most of the file, method name, line number, and column + information used in constructing StackFrame and StackTrace objects. StackTrace + might not report as many method calls as expected, due to code transformations + that occur during optimization." + + + This means that in a Release build the caller information may be incomplete or may + not exist at all! Therefore caller location information cannot be relied upon in a Release build. + + + + Additional pattern converters may be registered with a specific + instance using the method. + +

This is an insignificant overhead + since evaluating a logger takes about 1% of the time it + takes to actually log. This is the preferred style of logging. + + Alternatively if your logger is available statically then the is debug + enabled state can be stored in a static variable like this: + + + private static readonly bool isDebugEnabled = log.IsDebugEnabled; + + + Then when you come to log you can write: + + + if (isDebugEnabled) + { + log.Debug("This is entry number: " + i ); + } + + + This way the debug enabled state is only queried once + when the class is loaded. Using a private static readonly + variable is the most efficient because it is a run time constant + and can be heavily optimized by the JIT compiler. + + + Of course if you use a static readonly variable to + hold the enabled state of the logger then you cannot + change the enabled state at runtime to vary the logging + that is produced.

The results + depend on the conversion pattern. + + + The conversion pattern is closely related to the conversion + pattern of the printf function in C. A conversion pattern is + composed of literal text and format control expressions called + conversion specifiers. + + + You are free to insert any literal text within the conversion + pattern. + + + Each conversion specifier starts with a percent sign (%) and is + followed by optional format modifiers and a conversion + pattern name. The conversion pattern name specifies the type of + data, e.g. logger, level, date, thread name. The format + modifiers control such things as field width, padding, left and + right justification. The following is a simple example. + + + Let the conversion pattern be "%-5level [%thread]: %message%newline" and assume + that the log4net environment was set to use a PatternLayout. Then the + statements + + + ILog log = LogManager.GetLogger(typeof(TestApp)); + log.Debug("Message 1"); + log.Warn("Message 2"); + + would yield the output + + DEBUG [main]: Message 1 + WARN [main]: Message 2 + + + Note that there is no explicit separator between text and + conversion specifiers. The pattern parser knows when it has reached + the end of a conversion specifier when it reads a conversion + character. In the example above the conversion specifier + %-5level means the level of the logging event should be left + justified to a width of five characters. + + + The recognized conversion pattern names are: + + + + Conversion Pattern Name + Effect + + + a + Equivalent to appdomain + + + appdomain + + Used to output the friendly name of the AppDomain where the + logging event was generated. + + + + aspnet-cache + + + Used to output all cache items in the case of %aspnet-cache or just one named item if used as %aspnet-cache{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-context + + + Used to output all context items in the case of %aspnet-context or just one named item if used as %aspnet-context{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-request + + + Used to output all request parameters in the case of %aspnet-request or just one named param if used as %aspnet-request{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-session + + + Used to output all session items in the case of %aspnet-session or just one named item if used as %aspnet-session{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + c + Equivalent to logger + + + C + Equivalent to type + + + class + Equivalent to type + + + d + Equivalent to date + + + date + + + Used to output the date of the logging event in the local time zone. + To output the date in universal time use the %utcdate pattern. + The date conversion + specifier may be followed by a date format specifier enclosed + between braces.

However, + with the aid of format modifiers it is possible to change the + minimum field width, the maximum field width and justification. + + + The optional format modifier is placed between the percent sign + and the conversion pattern name. + + + The first optional format modifier is the left justification + flag which is just the minus (-) character. Then comes the + optional minimum field width modifier. This is a decimal + constant that represents the minimum number of characters to + output. If the data item requires fewer characters, it is padded on + either the left or the right until the minimum width is + reached. The default is to pad on the left (right justify) but you + can specify right padding with the left justification flag. The + padding character is space. If the data item is larger than the + minimum field width, the field is expanded to accommodate the + data. The value is never truncated. + + + This behavior can be changed using the maximum field + width modifier which is designated by a period followed by a + decimal constant. If the data item is longer than the maximum + field, then the extra characters are removed from the + beginning of the data item and not from the end. For + example, it the maximum field width is eight and the data item is + ten characters long, then the first two characters of the data item + are dropped. This behavior deviates from the printf function in C + where truncation is done from the end. + + + Below are various format modifier examples for the logger + conversion specifier. + +

+ + Note about caller location information.
+ The following patterns %type %file %line %method %location %class %C %F %L %l %M + all generate caller location information. + Location information uses the System.Diagnostics.StackTrace class to generate + a call stack. The caller's information is then extracted from this stack. +
+ + + The System.Diagnostics.StackTrace class is not supported on the + .NET Compact Framework 1.0 therefore caller location information is not + available on that framework. + + + + + The System.Diagnostics.StackTrace class has this to say about Release builds: + + + "StackTrace information will be most informative with Debug build configurations. + By default, Debug builds include debug symbols, while Release builds do not. The + debug symbols contain most of the file, method name, line number, and column + information used in constructing StackFrame and StackTrace objects. StackTrace + might not report as many method calls as expected, due to code transformations + that occur during optimization." + + + This means that in a Release build the caller information may be incomplete or may + not exist at all!

The Header and Footer + parameters for DynamicPatternLayout must be syntactically in the form of a PatternString, + but should not be marked as type log4net.Util.PatternString.

The results + depend on the conversion pattern. + + + The conversion pattern is closely related to the conversion + pattern of the printf function in C. A conversion pattern is + composed of literal text and format control expressions called + conversion specifiers. + + + You are free to insert any literal text within the conversion + pattern. + + + Each conversion specifier starts with a percent sign (%) and is + followed by optional format modifiers and a conversion + pattern name. The conversion pattern name specifies the type of + data, e.g. logger, level, date, thread name. The format + modifiers control such things as field width, padding, left and + right justification. The following is a simple example. + + + Let the conversion pattern be "%-5level [%thread]: %message%newline" and assume + that the log4net environment was set to use a PatternLayout. Then the + statements + + + ILog log = LogManager.GetLogger(typeof(TestApp)); + log.Debug("Message 1"); + log.Warn("Message 2"); + + would yield the output + + DEBUG [main]: Message 1 + WARN [main]: Message 2 + + + Note that there is no explicit separator between text and + conversion specifiers. The pattern parser knows when it has reached + the end of a conversion specifier when it reads a conversion + character. In the example above the conversion specifier + %-5level means the level of the logging event should be left + justified to a width of five characters. + + + The recognized conversion pattern names are: + + + + Conversion Pattern Name + Effect + + + a + Equivalent to appdomain + + + appdomain + + Used to output the friendly name of the AppDomain where the + logging event was generated. + + + + aspnet-cache + + + Used to output all cache items in the case of %aspnet-cache or just one named item if used as %aspnet-cache{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-context + + + Used to output all context items in the case of %aspnet-context or just one named item if used as %aspnet-context{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-request + + + Used to output all request parameters in the case of %aspnet-request or just one named param if used as %aspnet-request{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-session + + + Used to output all session items in the case of %aspnet-session or just one named item if used as %aspnet-session{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + c + Equivalent to logger + + + C + Equivalent to type + + + class + Equivalent to type + + + d + Equivalent to date + + + date + + + Used to output the date of the logging event in the local time zone. + To output the date in universal time use the %utcdate pattern. + The date conversion + specifier may be followed by a date format specifier enclosed + between braces.

+ + Note about caller location information.
+ The following patterns %type %file %line %method %location %class %C %F %L %l %M + all generate caller location information. + Location information uses the System.Diagnostics.StackTrace class to generate + a call stack. The caller's information is then extracted from this stack. +
+ + + The System.Diagnostics.StackTrace class is not supported on the + .NET Compact Framework 1.0 therefore caller location information is not + available on that framework. + + + + + The System.Diagnostics.StackTrace class has this to say about Release builds: + + + "StackTrace information will be most informative with Debug build configurations. + By default, Debug builds include debug symbols, while Release builds do not. The + debug symbols contain most of the file, method name, line number, and column + information used in constructing StackFrame and StackTrace objects. StackTrace + might not report as many method calls as expected, due to code transformations + that occur during optimization." + + + This means that in a Release build the caller information may be incomplete or may + not exist at all! Therefore caller location information cannot be relied upon in a Release build. + + + + Additional pattern converters may be registered with a specific + instance using the method. + +

This is an insignificant overhead + since evaluating a logger takes about 1% of the time it + takes to actually log. This is the preferred style of logging. + + Alternatively if your logger is available statically then the is debug + enabled state can be stored in a static variable like this: + + + private static readonly bool isDebugEnabled = log.IsDebugEnabled; + + + Then when you come to log you can write: + + + if (isDebugEnabled) + { + log.Debug("This is entry number: " + i ); + } + + + This way the debug enabled state is only queried once + when the class is loaded. Using a private static readonly + variable is the most efficient because it is a run time constant + and can be heavily optimized by the JIT compiler. + + + Of course if you use a static readonly variable to + hold the enabled state of the logger then you cannot + change the enabled state at runtime to vary the logging + that is produced.

The results + depend on the conversion pattern. + + + The conversion pattern is closely related to the conversion + pattern of the printf function in C. A conversion pattern is + composed of literal text and format control expressions called + conversion specifiers. + + + You are free to insert any literal text within the conversion + pattern. + + + Each conversion specifier starts with a percent sign (%) and is + followed by optional format modifiers and a conversion + pattern name. The conversion pattern name specifies the type of + data, e.g. logger, level, date, thread name. The format + modifiers control such things as field width, padding, left and + right justification. The following is a simple example. + + + Let the conversion pattern be "%-5level [%thread]: %message%newline" and assume + that the log4net environment was set to use a PatternLayout. Then the + statements + + + ILog log = LogManager.GetLogger(typeof(TestApp)); + log.Debug("Message 1"); + log.Warn("Message 2"); + + would yield the output + + DEBUG [main]: Message 1 + WARN [main]: Message 2 + + + Note that there is no explicit separator between text and + conversion specifiers. The pattern parser knows when it has reached + the end of a conversion specifier when it reads a conversion + character. In the example above the conversion specifier + %-5level means the level of the logging event should be left + justified to a width of five characters. + + + The recognized conversion pattern names are: + + + + Conversion Pattern Name + Effect + + + a + Equivalent to appdomain + + + appdomain + + Used to output the friendly name of the AppDomain where the + logging event was generated. + + + + aspnet-cache + + + Used to output all cache items in the case of %aspnet-cache or just one named item if used as %aspnet-cache{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-context + + + Used to output all context items in the case of %aspnet-context or just one named item if used as %aspnet-context{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-request + + + Used to output all request parameters in the case of %aspnet-request or just one named param if used as %aspnet-request{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-session + + + Used to output all session items in the case of %aspnet-session or just one named item if used as %aspnet-session{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + c + Equivalent to logger + + + C + Equivalent to type + + + class + Equivalent to type + + + d + Equivalent to date + + + date + + + Used to output the date of the logging event in the local time zone. + To output the date in universal time use the %utcdate pattern. + The date conversion + specifier may be followed by a date format specifier enclosed + between braces.

However, + with the aid of format modifiers it is possible to change the + minimum field width, the maximum field width and justification. + + + The optional format modifier is placed between the percent sign + and the conversion pattern name. + + + The first optional format modifier is the left justification + flag which is just the minus (-) character. Then comes the + optional minimum field width modifier. This is a decimal + constant that represents the minimum number of characters to + output. If the data item requires fewer characters, it is padded on + either the left or the right until the minimum width is + reached. The default is to pad on the left (right justify) but you + can specify right padding with the left justification flag. The + padding character is space. If the data item is larger than the + minimum field width, the field is expanded to accommodate the + data. The value is never truncated. + + + This behavior can be changed using the maximum field + width modifier which is designated by a period followed by a + decimal constant. If the data item is longer than the maximum + field, then the extra characters are removed from the + beginning of the data item and not from the end. For + example, it the maximum field width is eight and the data item is + ten characters long, then the first two characters of the data item + are dropped. This behavior deviates from the printf function in C + where truncation is done from the end. + + + Below are various format modifier examples for the logger + conversion specifier. + +

+ + Note about caller location information.
+ The following patterns %type %file %line %method %location %class %C %F %L %l %M + all generate caller location information. + Location information uses the System.Diagnostics.StackTrace class to generate + a call stack. The caller's information is then extracted from this stack. +
+ + + The System.Diagnostics.StackTrace class is not supported on the + .NET Compact Framework 1.0 therefore caller location information is not + available on that framework. + + + + + The System.Diagnostics.StackTrace class has this to say about Release builds: + + + "StackTrace information will be most informative with Debug build configurations. + By default, Debug builds include debug symbols, while Release builds do not. The + debug symbols contain most of the file, method name, line number, and column + information used in constructing StackFrame and StackTrace objects. StackTrace + might not report as many method calls as expected, due to code transformations + that occur during optimization." + + + This means that in a Release build the caller information may be incomplete or may + not exist at all!

This is the preferred style of logging. + + Alternatively if your logger is available statically then the is debug + enabled state can be stored in a static variable like this: + + + private static readonly bool isDebugEnabled = log.IsDebugEnabled; + + + Then when you come to log you can write: + + + if (isDebugEnabled) + { + log.Debug("This is entry number: " + i ); + } + + + This way the debug enabled state is only queried once + when the class is loaded.

PatternLayout is a 'static' class + in that its layout is done once at configuration time. This class will recreate + the layout on each reference. + One important difference between PatternLayout and DynamicPatternLayout is the + treatment of the Header and Footer parameters in the configuration. The Header and Footer + parameters for DynamicPatternLayout must be syntactically in the form of a PatternString, + but should not be marked as type log4net.Util.PatternString. Doing so causes the + pattern to be statically converted at configuration time and causes DynamicPatternLayout + to perform the same as PatternLayout. + Please see for complete documentation. + + <layout type="log4net.Layout.DynamicPatternLayout"> + <param name="Header" value="%newline**** Trace Opened Local: %date{yyyy-MM-dd HH:mm:ss.fff} UTC: %utcdate{yyyy-MM-dd HH:mm:ss.fff} ****%newline" /> + <param name="Footer" value="**** Trace Closed %date{yyyy-MM-dd HH:mm:ss.fff} ****%newline" /> + </layout> + + + + + + A flexible layout configurable with pattern string. + + + + The goal of this class is to a + as a string. The results + depend on the conversion pattern. + + + The conversion pattern is closely related to the conversion + pattern of the printf function in C. A conversion pattern is + composed of literal text and format control expressions called + conversion specifiers. + + + You are free to insert any literal text within the conversion + pattern. + + + Each conversion specifier starts with a percent sign (%) and is + followed by optional format modifiers and a conversion + pattern name. The conversion pattern name specifies the type of + data, e.g. logger, level, date, thread name. The format + modifiers control such things as field width, padding, left and + right justification. The following is a simple example. + + + Let the conversion pattern be "%-5level [%thread]: %message%newline" and assume + that the log4net environment was set to use a PatternLayout. Then the + statements + + + ILog log = LogManager.GetLogger(typeof(TestApp)); + log.Debug("Message 1"); + log.Warn("Message 2"); + + would yield the output + + DEBUG [main]: Message 1 + WARN [main]: Message 2 + + + Note that there is no explicit separator between text and + conversion specifiers. The pattern parser knows when it has reached + the end of a conversion specifier when it reads a conversion + character. In the example above the conversion specifier + %-5level means the level of the logging event should be left + justified to a width of five characters. + + + The recognized conversion pattern names are: + + + + Conversion Pattern Name + Effect + + + a + Equivalent to appdomain + + + appdomain + + Used to output the friendly name of the AppDomain where the + logging event was generated. + + + + aspnet-cache + + + Used to output all cache items in the case of %aspnet-cache or just one named item if used as %aspnet-cache{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-context + + + Used to output all context items in the case of %aspnet-context or just one named item if used as %aspnet-context{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-request + + + Used to output all request parameters in the case of %aspnet-request or just one named param if used as %aspnet-request{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + aspnet-session + + + Used to output all session items in the case of %aspnet-session or just one named item if used as %aspnet-session{key} + + + This pattern is not available for Compact Framework or Client Profile assemblies. + + + + + c + Equivalent to logger + + + C + Equivalent to type + + + class + Equivalent to type + + + d + Equivalent to date + + + date + + + Used to output the date of the logging event in the local time zone. + To output the date in universal time use the %utcdate pattern. + The date conversion + specifier may be followed by a date format specifier enclosed + between braces.

However, + with the aid of format modifiers it is possible to change the + minimum field width, the maximum field width and justification. + + + The optional format modifier is placed between the percent sign + and the conversion pattern name. + + + The first optional format modifier is the left justification + flag which is just the minus (-) character. Then comes the + optional minimum field width modifier. This is a decimal + constant that represents the minimum number of characters to + output. If the data item requires fewer characters, it is padded on + either the left or the right until the minimum width is + reached. The default is to pad on the left (right justify) but you + can specify right padding with the left justification flag. The + padding character is space. If the data item is larger than the + minimum field width, the field is expanded to accommodate the + data. The value is never truncated. + + + This behavior can be changed using the maximum field + width modifier which is designated by a period followed by a + decimal constant. If the data item is longer than the maximum + field, then the extra characters are removed from the + beginning of the data item and not from the end. For + example, it the maximum field width is eight and the data item is + ten characters long, then the first two characters of the data item + are dropped. This behavior deviates from the printf function in C + where truncation is done from the end. + + + Below are various format modifier examples for the logger + conversion specifier. + +

+ The following patterns %type %file %line %method %location %class %C %F %L %l %M + all generate caller location information. + Location information uses the System.Diagnostics.StackTrace class to generate + a call stack. The caller's information is then extracted from this stack. +
