User found that several indicators were alarming in APM even though the most recent reading for those indicators was normal and the Indicator Alarm State Policy select was to reflect the most recent reading.
This problem can have multiple root causes.
Example 1:
There is a setting that determines whether an indicator alarms in the indicator panel based on most recent reading or based on most severe unacknowledged alarm associated with that indicator.
This setting is a point in time setting, ie, if you change it the indicators currently in alarm will continue to have a condition of "has alarm" until the prior readings in alarm have all been addressed. Long story short, you need to address the previous, historical readings still awaiting action for those alarms to disappear. This can be done via acknowledging the historic alarms, either with an incorrect alarm or fixed during inspection acknowledgement.. Once this has been done for all reading made before the setting was changed to "Most recent reading", then future readings will behave as expected under the new setting.
Example 2:
For some reason that we have not been able to reproduce to date, an alarm acknowledgement will not propagate successfully to all nodes - from indicator reading, to indicator, to Asset.
Example 3:
Alarm readings not acknowledged in a previous release of APM may be problematic and not acknowledge successfully after an upgrade
This should occur very infrequently. Please report an SR if you become aware of a reproducible use case that will cause this condition.
To clear incorrect alarm state on Indicator reading, Indicator or Asset, we will trigger a new cascade/propagation of alarm setting and clearing.
Ensure that the Indicator object window is NOT open on screen when doing steps 2 and 3.
1. Determine the highest Alarm state for the Indicator in question
2. Enter a reading to invoke this state. This will cascade the alarm to related objects
3. Mark the reading as incorrect. This will clear the alarm on related objects
