User behavior data collection

[yurii-yu]

As a developer, I want know the general user behaviors so that I can improve the user experience.

It would be the best, if there is a way to observe the behavior of user. Then we know a lot aspects about the end-user experience.

for example

1. which commands do our users type most frequently?
2. which errors occur most frequently?
3. Is there any misunderstanding of the commands? then we can improve either the interface or the documents
4. which commands last for the longest time? is there any chance to optimize this?

How would we store such data?
IMHO adding a database to IDEasy could be overkill. So add a JSON file? Will that be centrally for all projects in $IDE_ROOT/_ide?
If so how would we prevent file corruption due to concurrent invocations of IDEasy?

Can we already design the data-structure:

• «tool»:
  • «additional arguments»:
    • error
      • «error-codes»: «number-of-occurences»
    • success
      • «average-duration» (or better "total duration" + "number of runs" so we can build average with high precision and less rounding errors?)

Example:

{
  "mvn": {
    "clean install": {
      "error": {
        "1": 297
      },
      "success": {
        "duration": 12345678901234,
        "runs": 931
      }
    }
  },
 "install": {
    "mvn": {
       ...
    }
  },
  "update": {
    "": {
      ...
    }
  },
  ...
}

Are there best-practices on the web how to do such things? Maybe an existing library to reuse?
