Default message format
To have an idea of what a notification without any customization looks like, we're going to use a very simple example. Take the following alerting rule, which we defined in our Prometheus instance:
- alert: deadmanswitch expr: vector(42)
As soon as this alert starts firing, an alert payload will be sent to Alertmanager. The following snippet demonstrates the payload being sent. Note the labels that are present, which include the alertname and the external_labels from the Prometheus instance:
{ "labels": { "alertname": "deadmanswitch", "dc": "dc1" }, "annotations": {}, "startsAt": "2019-04-02T19:11:30.04754979Z", "endsAt": "2019-04-02T19:14:30.04754979Z", "generatorURL": "http://prometheus:9090/graph?g0.expr=vector%2842%29&g0.tab=1" ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
