Alerts not working


I am new to graylog, so probably is a my fault, but i am facing problems with Alerts.
I am using Graylog 3.2.6+e255fcc on Ubuntu 20.04 LTS.

I am trying to make an Alert when a stream is not sending data, to monitor the status of the streams, but i recieve no alert at all. This is my configuration:

I have also tried to stop completely the stream from the source rsyslog, but no alert is generated.

How i can debug this problem?


Check this:

Thank you for your response, but it seems not working properly.
Now i see the events correctly generated, but wrong.

I have made this test: i have 2 sources, i have stopped 1 and the other is continuing sending logs.

After waiting for the Alerts been triggered, i have recieved 2 events of “30 minutes silent sender”, for all the two streams. But i have checked and the other stream is sended data in the last 10 minutes.

Something is wrong, but i don’t know how to debug the problem.
