      Solution to count and monitor log events in CTA

      • Adopting OpenTelemetry can be a risk (vs the option of creating our own mechanism).
      • In addition, we may not need all the complexity that it provides.
      • Task 1: Select 1 or 2 use cases.
      • Task 2: Check which infrastructure would need to be used.
      • Task 3: Experiment and prototype on a separate branch. Have a POC.

      Allow VO override for repack

      • We will call the new column IS_REPACK_VO.

      Review error messages for prepare abort

      • We need to find ways to improve our error messages returned with query prepare.


      • Add new fields to the file xattrs that help improving the "error_text" message in the query prepare command (For example "[123456789.00][cta-taped] trigger workflow - synchronous workflow failed"). Examples:
        • Timestamp
        • Message type
        • Message origin (cta-taped, cta-frontend, EOS, ...)
        • Etc...
      • Check existing xattrs.
      • Review default "error_text" messages filed by EOS. Check if they are adjusted to each specific scenario.
      • Review mechanism that passes messages from CTA to EOS (&mgm.errmsg= field).

      Unify permission configuration across different CTA tools

      • Needs more investigation.
