I was looking for a solution to generate an alert if there’s no syslog received from device for a specified period of time.
IF no syslog received last 24 hours THEN generate alert
Have tried with something like
syslog.timestamp != macros.past_5m but that doesn’t work as expected. Maybe I’m misunderstanding something here.
I believe I’m missing something too obvious here or this requirement is just not applicable in LibreNMS.
Will appreciate any thoughts on this.
