What about logs from alertmanager itself? Add "--log.level=debug" to alertmanager's command line args to get maximum debugging.
You could also try using tcpdump to see if a message is sent from alertmanager to prometheus-msteams: tcpdump -i lo -nn -s0 -X tcp port 2000 Also you mentioned helm charts in passing, implying kubernetes is being uesd. The destination "localhost" is only going to work if prometheus-msteams is running in the same pod as alertmanager. If that's not the case, then you'll have to give it the correct endpoint instead of "localhost". -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
