Trying to set up alertmanager on a running prometheus instance. I can see alerts via Grafana, so I know alerts are happening. However, there are no log entries (as there are with other ideas) that say “alertmanager is not found” or "alertmanager not working because ". I have absolutely no indication that alertmanager is not working except for the lack of alerts.
I would like to open a github issue about this, but I need to know why alertmanager is failing to alert first, so I can ask for the inclusion of any log message that will give users a fighting chance to find out what is wrong.
I have the following in prometheus config:
alerting: alertmanagers: - static_configs: - targets: - 184.108.40.206:8765
I start alertmanager with
--cluster.listen-address='' --web.listen-address= 220.127.116.11:8765 --log.level=debug
Why isn’t this working?
Thanks in advance.
