Currently have a EUM Alert configured as follows:
Trigger Condition tab:
Event based trigger = Transaction fails
Data Grouping = checked
Filters tab - no values checked
Actions tab - Send to specified recipients checked
Advanced Settings tab - Send no more than one alert as long as the conditions that triggered the alert continue to exist
Trigger conditions is set to "at least 2 times out of 3"
Data Grouping is set to "group data by business transaction flow"
With this alert configuration running against a BTF containing 5 transactions the following occurred:
Run 1: First three transactions ran, 4th failed and 5th never occurred.
Run 2: First transaction ran, second failed (alert triggered), third transaction completed, 4th transaction failed (alert triggered), 5th never occurred.
Run 3: First three transactions ran, 4th failed and 5th never occurred.
Run 4: All 5 transactions completed successfully.
Need to understand why two alert triggers were generated on the second run. Run 1 fail and first fail on run two would surely initiate a fail (and alert), though after that seems that the alert criteria would be reset and logic would seem to state the the second fail on run two would be starting a new "2 out of 3 fail" criteria round, not raising another alert.
NOTE: information in the Help for BSM 9.25 does not cover setting for "business transaction flow" (at least what I could find )
