MDM 15.3.0 Upgrade Notes

Improved validation in ONE Desktop

We have introduced new validation checks for configuring workflows, tasks, and permissions in ONE Desktop. After the upgrade, some configurations that were previously considered valid might now trigger validation errors, even though they can still be deployed and run without issues.

Review validation errors that appear after the upgrade and correct the configurations as necessary.

New Prometheus metrics

We have added two Prometheus metrics for monitoring thread pool performance:

  • dqc_threadpool_threads_created_total: Total threads created in the pool.

  • dqc_threadpool_threads_finished_total: Total threads that have completed execution.

The difference between these metrics shows the current number of active threads, which helps with load monitoring.

Configuration changelog

This section provides the information about the changes in the configuration files that need to be taken into account when upgrading the solution. In certain cases, the newly introduced default is used or some configuration is required.
