Hi,

With the AutoClear = False in the alarm template, it's possible not to clear the alarms automatically. In this case, alarms will move to clearable and not closed state (Clearing alarms | DataMiner Docs).

However, if the system is in Alarm Storm mode, it can happen that the alarms are closed even with the AutoClear = False. By default, when there are more than 1000 clearable alarm trees on a DMA, the newly generated clearable alarms will be closed instead of being clearable. Once the number of clearable alarm trees has dropped to less than 100, this protection mode is lifted, and newly generated alarms will be clearable again.

I saw that it's possible to use the ClearableAlarmStormProtection setting in the DataMiner.xml file and change the default max/min values: ClearableAlarmStormProtection element | DataMiner Docs

Is there any advice/rule to help define the ClearableAlarmStormProtection max and min values?
