I’ve been using LibreNMS for a while and it works great. The email notification works fine for the default alert rules. I’ve installed the agent on a couple of hosts and added a custom alert rule (check for a specific process). The alert triggers just fine, but it seems to have a problem with sending an email notification. Are these using different email configurations?
I get alert emails for the default alert rules, but I get a for my custom rule.
I’ve just tested this exact rule and it worked fine for me:
Alert for device localhost - fatcontroller
Severity: critical
Timestamp: 2017-02-07 20:56:06
Unique-ID: 22467
Rule: fatcontroller
Faults:
#1: pid => 1;
Alert sent to: NOC <redacted>
You could run the alerts capture for the device you expect to see this for and see what email address would be used.
Also worth noting the match on like uses mysql regex so your rule wouldn’t match unless the process command was exactly what you entered. At most you want @fatcontroller@ (@ is a wildcard for us)
