Can Grafana make a phone call when an alert fires?

Not on its own. Add Edesy OnCall's alert webhook URL as a Webhook contact point and route your critical alerts to it. Each firing alert then becomes an OnCall incident that phones your team.

Which Grafana version do I need?

Any Grafana with unified alerting and the Webhook contact point type. OnCall reads the standard alerting webhook payload: the alerts list with status, labels, annotations and fingerprint.

Does a resolved alert stop the phone calls?

Yes. Grafana sends resolved notifications by default; OnCall closes the matching incident, stops escalation and emails everyone who was paged.

What does the on-call engineer hear?

Your organisation name, the OnCall monitor name, when the incident opened and the alert's summary annotation, or its alertname if there is no summary.

An alert webhook monitor counts as one monitor. The Free plan includes 3, and alert calls are billed per minute from your Edesy wallet.

Grafana Phone Call Alerts

Grafana alerting can't phone anyone by itself. Add Edesy OnCall as a Webhook contact point and each firing alert opens an OnCall incident that calls your team in English or Hindi, escalating until someone presses 1. When Grafana sends resolved, the incident closes. It takes one contact point and one notification policy.

Connect Grafana to OnCall

About five minutes

Step 1 of 5: Create an alert webhook monitor
In OnCall, add an Alert webhook monitor named after the Grafana stack, attach an escalation policy and copy the URL.
Step 2 of 5: Add a contact point
In Grafana, go to Alerting, Contact points, Add contact point. Choose Integration: Webhook, paste the URL and keep the method POST.
Step 3 of 5: Route critical alerts
In Notification policies, add a policy that matches your critical label (for example severity=critical) and sends to the Edesy OnCall contact point.
Step 4 of 5: Add a summary
Give each alert rule a short summary annotation. It is read aloud on the call.
Step 5 of 5: Test
Use Test on the contact point, then check the incident and the call in OnCall.

Provision the contact point as code

The same contact point in Grafana's file provisioning format. Replace the URL with the one from your OnCall monitor.

# Grafana provisioning: alerting/contact-points.yaml
apiVersion: 1
contactPoints:
  - orgId: 1
    name: Edesy OnCall
    receivers:
      - uid: edesy-oncall
        type: webhook
        settings:
          url: https://oncall.edesy.in/ingest/<token>
          httpMethod: POST

Grafana plus OnCall gives you

A phone call for the alerts that matter, from the rules you already have
Press 1 to acknowledge, press 2 to hand it to the next person
Escalation to a second and third person with wait times
One incident per alert, closed automatically when Grafana resolves it

Good to know

Grafana keeps doing detection; OnCall only calls and emails
Keep your chat contact points for non-critical alerts
No on-call schedules in OnCall: edit the policy when duty changes
Alert text is read aloud, so leave personal data out of it
