Does anybody know if there is a way to create an alarm for when one of the data source stops collecting logs? So let's say whenever one of my data sources hasn't received a new log in 3 days, it would raise an alert? Thanks!
When creating an alarm, you have a condition named "Device status change". You can select this, then check "Idle time".
Then in "Devices" tab, select all.
You can't however choose the timeframe after which it will trigger. You can only choose the alarm frequency (minimum time between two triggers).
In the Alarm I used an internal event match to signature ID 306-50014, and a separate one for device status change condition for SIEM devices. based upon the receivers and associated devices.
I backtracked these through some opsec events somewhere, I believe a health reference doc in knowledge base.
