How to start sending alerts to Grafana OnCall from AlertManager

1. 1. Add the new receiver to the AlertManager configuration file:

           receivers:
           - name: 'grafana_oncall'
             webhook_configs:
             - url: {{ alert_receive_channel.integration_url }}
               max_alerts: 100
           

   2. Use receiver in route tree: routes: - matchers: - severity="critical" receiver: grafana_oncall
