Help With Alert Rule

Do you put anything in the alert rule next to “Map to”?

As a test, I am trying to get an alert when storage passes 10% (just as a test) on a Windows server. I have "%storage.storage_perc > 10 && %devices.type = “Server” and

Max: -1
Delay: 300
Interval: 1800

Even though I have a Windows server with 17% storage used on the C: drive, this isn’t alerting. In alert history, it looks like the alert is being tested against my switches.

If you want to use Rule Mapping then need to that under Alert rule mapping.
See doc on alert rule mapping. Home - LibreNMS Docs

To test and see the alert rule matches see https://docs.librenms.org/#Support/Device-Troubleshooting/#alerts

Can you post a screenshot of the Alert rule you are working on?

I think this what you were trying to doimage
