Alerts not working in Graylog 3.1.4

My Graylog server is not triggering any alerts even though my Alerts & Events definitions are correctly configured. I checked the Filter and Aggregation tabs, and the error message has appeared but does not trigger any alerts. The server’s error log does not show any logs related to this situation.

  • OS Information: CentOS 7
  • Package Version: 3.1.4

I have tried restarting the service several times, but the issue persists and reoccurs after a few days."

Hey @lekha

Did you check your mail logs?

/var/log/mail

Thanks for the reply, but the mail logs do not exist.

Does it mean, after restart alerts are working, then stops after some days?

Yes, I think something happened with the event catching.
I make some test cases and the results is:

In old versions of GL alerts only fire when there are incoming messages. This has been improved in recent versions. 3.1.4 has been out of support for quite a while.
