|

|
The "data collector" is a lightweight microservice application that collect and sends metadata, collected from a system, such as an IoT network, distributed system, data center, etc to a storage system.
|
|
|
|
|
|
* The data are transmitted, stored, and can be retrieved at any time.
|
|
|
|
*"data collector"* are developed with a platform agnostic"container-based application strategy
|
|
|
|
[NOTE]
|
|
====
|
|
|
|
A platform-agnostic approach offers many choices
|
|
|
|
* Can be seamlessly moved from local development machine to production deployments
|
|
|
|
* Flexibility, Reliability
|
|
|
|
** Avoiding Vendor Lock-In
|
|
|
|
* From Code to full-blown systems
|
|
|
|
** from a single container on your local machine
|
|
|
|
** to a running cloud native - container-based environment

* (1) Opens the info menu
|
|
* (2) Run a shell in a running container
|
|
* (3) Opens web interface
|
|
* (4),(5) Source directory - Directory Maps

|
|
|
*"Directory Maps"* are the preferred mechanism for persisting data generated and used by Docker containers. We use here "bind mounts" and they are dependent on the directory structure and OS of the host machine.
