What Grafana version and what operating system are you using?
Grafana v8.0.3 running on docker with ngalert feature enable
What are you trying to achieve?
Fire alert immediately
How are you trying to achieve it?
- enable ngalert feature
- add a new alert rule
- configure evaluate for filed to 0s (the original alert feature allows to set 0s, but ngalert doesn’t)
I can not set evaluate for to 0, the ui shows it can not be less than 10s
What did you expect to happen?
set to 0, so that we can trigger alert immediately without pending state
Can you copy/paste the configuration(s) that you are having problems with?
Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
