Hi, all!

Brief query, you know why in the SLCorrelation there are events that after the MATCH legend add the label no change as shown in the following screenshot:

Because sometimes this correlation is not executing the actions defined, which is to execute a script and there are a couple of correlations similar to this one that do not log the label: no change.

I hope you can help me with this concern.

Regards

Hi,

Alarms that get processed by the correlation engine end up in different buckets based on the filter and alarm grouping.  When an alarm for a bucket gets processed, the "condition" gets evaluated.  After successful evaluation of the condition you see either:

  • ===== MATCH ======= : the condition of the bucket is met due to this last event.  (So the condition was until this event not fulfilled)
  • ====== MATCH ======= [no change] : the condition of the bucket is met, but the state of the condition did not change due to this last event. (so the condition was already met before this event)
