Alarming outside patern

Hi all.

I am monitoring an antenna which on a one week time frame has always a patern for one of the parametars(Elevation in this case). This would be the correct way of working.

It might happen that a mechanical issue can occur; the alarm template will not trigger any alarm because no threshold has been passed.

How can I create an alarm in the case of a mallfunction that keeps the value of a parameter for more than 1 hour on the same level ?  this is a use case of breaking the patern; having the same value for a certain period could mean something is broken and I would like to get notified.

Thanks.

Hi Daniel,

Maybe some of the dynamic alarming capabilities may help you out.  Configuring dynamic alarm thresholds | DataMiner Docs

This allows you for example to do your monitoring of a metric by comparing it to the value of that metric at around the same time but in the past x days.

Alternatively (for your specific use case) you can also leverage the Flatline detection (go to ANALYTICS details of your metric in the Alarm Template and activate the option “Detect flatlines”).  Working with behavioral anomaly detection | DataMiner Docs
