Data collector

Task

Implement a service that collects system information upon reception of a trigger event. The trigger event is raised when existence of a file with a certain name in a specified directory is detected.

The following features must be implemented:

• Trigger detection
  • Detect creation of a file in a somehow specified directory
  • Make the directory configurable via commandline parameter
  • Only trigger on files with names following this format:
    • Starts with core.<variable name of a service>.
    • Ends with lz4
    • Contains one or more hexadecimal id separated by dots
    • Example: core.ServiceName.3057.57dd721409bc4ab4b38a3c33a36a608a.3717.1647975805000000.lz4
• Collected data shall be:
  • Individual files, as well as whole directories and their contents, recursively, configured via command line parameter
• Store the collected data in a configurable directory, create a tar-archive of the aforementioned contents
  • Give the resulting file a unique name.
• Add tests to make sure your application is working,
  • How tests are implemented is up to you

Things to keep in mind

• Implement your collection in a way such that it can be extended to collect other data of various forms later.
• Use modern C++!
• Use the platform of your choice (Linux, BSD, MacOS, Windows, etc.)
  • We use Linux but everything else is cool, too.
