We made a change to an alarm template to remove a hysteresis, but when the parameter changes to an alarm state, the alarm is not raised in dataminer until the hysteresis time passes. Is there any known issue or bug that could be causing this?
When some parameter has hysteresis configured and then hysteresis is disabled (by setting time to 0 or by removing the value completely in the alarm template), it remains active.
This is a known issue (107485).
The issue is present in standalone parameters, doesn’t reproduce with table parameters.
In order to resolve this do the following:
To disable hysteresis and bring the alarm template to the initial state, one must uncheck all severities, apply, then check all severities again.
Element restarts resolves it as well as is less impactful as workaround.
FYI: it is present in all versions
