Create a rule to detect number of beats

Elastic Security SIEM
1

Hello,

I would like to create a new rule to detect if one of my beats stop sending data to my Cluster (one rule for each beat).
For example I have installed packetbeat in 5 machines, and then the rule will verify each 1 minutes the number of agent.host (by aggregation) and if it's less than 5, then it will send me an alert.

Could you please tell me how can I create this kind of alerts

Thanks in advance :slight_smile:

Which version of Elastic are you running?
You should use the latest version and using the threshold based rule.

thanks for your answer @Felix_Roessel ,

But if I understand well, in the threshold based rule I can only use greater than and there is no way to say less than !!

Oh yes, you are right.
In that case I would recommend choosing an ML based rule. The job will check for the normal amount of events / beats / hosts and inform you whenever there is a change.

Its the easiest way to do so.
