Nagios Support Forum

Hi,

Any idea to create an alert if I haven't received any logs from a IP for ex 1 hour ?

Found it

"Thresholds - This is what triggers the alert. A common use of the host freshness check is to detect when a host is no longer sending logs to Nagios Log Server. By using 0 for both warning and critical this will trigger a critical condition. Host Freshness alerts run once per hour and observe logs over the same amount of time"

That will do it. I'd only add out that alerts cant accept the Nagios threshold syntax which is covered in https://nagios-plugins.org/doc/guidelin ... HOLDFORMAT and the freshness checks work by searching the 'Not Sending' table under Reports.
