Meter Session Status Change

View as Markdown

The Meter Session Status Change event triggers when a Mediation meter session changes status.

For example, it can trigger when a session moves from RUNNING to COMPLETED or FAILED. You can use this event for both NORMAL and DEBUG/TESTING runs. Typical uses include alerting operations teams when a production meter run fails or sending completion notifications when a large batch run finishes.
