Alerting: After one firing it wont alert again. Why?

Hi everyone :slight_smile:

I have a question regarding my alerting system for a normal e-mail account.

  • First of all i am running a grafana cloud instance (version 9.0.2.) on my linux machine.
  • I want to continuously get an alert when my value exceeds 3500 (see the picture below)

Right now if i create the alarm it will work for the first time it fires a alert and i receive a e-mail as the following:

but the following cycles (every 10 min) i wont receive anything. I have set the Alert behaviour and the details to this:

My alerting page still shows me the first alerts and that it is firing for 1h 26m and my values are still exceeding 3500 inside my graph.

Are there any changes i have to do to receive the alerting automatically in my email-account ?

Thank you in advance :slight_smile: Greetings Grafu

same problem, its alerting once email

I would like to bump this.

I can’t figure out how to refire alert. I’m using Grafana 9.3.2 with PostgreSQL datasource, getting the count of errors that happened in last 30 min via SQL query and then checking if that count is above zero. Alert itself evaluates every 30 minutes too, evaluate for is set to 0s. So it boils down to two situations:

  1. Alert fires, then after another 30 minutes if there are no NEW errors, Resolve is received.
  2. Alert fires, then in the next 30 minutes there are NEW errors, but alert doesn’t fire again, instead it just stays silent.

Is there a way to make it fire again in case 2? Thank you!

You’ll want to check out the Group wait, Group interval and Repeat interval preferences under Notification policies.

If we use 2 or 3 servers and they are not getting the email, then what should we do now? For 2, 3, and 4 servers, how do we get continuous email?

I followed what you said above. I just gave the contact point and group by (grafana_folder, alertname), and the group wait is 30s, the group interval is 30s, and the repeat interval is 30s. i gave them something like this and I am getting some time after those The contact point and notification policy says that because there are too many, it fails to send email. I solved this issue with SMTP grafana.ini hear it’s my man’s problem. How do I send an alert to email after firing the alert? Until I resolve the issue, I need to send notifications to the email alert. In my scenario 3, 4 servers are there, and for each server’s CPU, memory, and disk, is there a way to send an alert notification continuously to email after firing?

Could you please reply? how to get continuous alert notification to emails for more than one server
