Alertmanager and Grafana

Alertmanager (standalone, or the one bundled with Grafana’s alerting) can call a webhook receiver directly. InfraInbox accepts its native payload, so nothing changes on the Prometheus or Grafana side beyond adding a receiver or contact point.

Tested with: Alertmanager 0.28, Grafana 11+.

What you get

Section titled “What you get”

A firing alert opens an incident; the matching resolved notification closes it, matched by Alertmanager’s own alert fingerprint. The shipped preset sets firing alerts to never auto-expire — only the resolved notification is trusted to close them, since Alertmanager already tracks that state for you.

Prerequisites

Section titled “Prerequisites”
  • Alertmanager (or Grafana’s alerting) able to reach your InfraInbox server over HTTPS.
  • send_resolved: true on the receiver, or you’ll never see an incident close on its own.

Setup

Section titled “Setup”

Alertmanager

Section titled “Alertmanager”

  1. Go to Add source → Alertmanager and name it. Copy the issued ingest key.

  2. Add a receiver to alertmanager.yml and route alerts to it:

    receivers:
      - name: infrainbox
        webhook_configs:
          - url: https://infrainbox.example.com/hooks/alertmanager
            send_resolved: true
            max_alerts: 500
            http_config:
              authorization:
                credentials: iik_src_…

  3. Reload Alertmanager and click through a route to infrainbox, or trigger a real alert to confirm.

Grafana

Section titled “Grafana”

  1. Alerting → Contact points → Add contact point, integration Webhook.

  2. Fill in:

    Field Value
    URL https://infrainbox.example.com/hooks/alertmanager
    HTTP Method POST
    Authorization Header Scheme Bearer
    Authorization Header Credentials iik_src_…

  3. Click Test. The source shows Reachable.

  4. Point a notification policy at the contact point.

Check it works

Section titled “Check it works”

Trigger an alert (or use Grafana’s Test button) and confirm the source switches to Receiving events and an incident opens. Let the alert clear and confirm the incident resolves.

Limitations

Section titled “Limitations”

One InfraInbox source can take every Alertmanager or Grafana instance’s alerts you want grouped the same way — split them into separate sources only if you want separate routing or separate presets.
