Proxy Prometheus Alertmanager webhooks to OpsGenie Heartbeat API to work around issue discussed here prometheus/alertmanager#444

Docker container can be pulled here traumfewo/opsgenie-heartbeat-proxy.

Provide OpsGenie API Key and Heartbeat name as env variable.

docker run -e OPSGENIE_API_KEY='<API-KEY>' -e HEARTBEAT_NAME='<HEARTBEAT_NAME>' -d -p 8080:8080 traumfewo/opsgenie-heartbeat-proxy:latest

For debbuging purpose you can use optional DEBUG env.

Setup an always firing prometheus alert

ALERT OpsGenieHeartBeat
      IF vector(1)
      LABELS { app = "opsgenie" }
      ANNOTATIONS {
        description = "Ping OpsGenie heartbeat api.",
      }
