This is an alert meant to ensure that the entire alerting pipeline is functional.
|
|
This alert is always firing, therefore it should always be firing in Alertmanager
|
|
and always fire against a receiver. There are integrations with various notification
|
|
mechanisms that send a notification when this alert is not firing. For example the
|
|
"DeadMansSnitch" integration in PagerDuty.

This is an alert that is used to inhibit info alerts.
|
|
By themselves, the info-level alerts are sometimes very noisy, but they are relevant when combined with
|
|
other alerts.
|
|
This alert fires whenever there's a severity="info" alert, and stops firing when another alert with a
|
|
severity of 'warning' or 'critical' starts firing on the same namespace.
|
|
This alert should be routed to a null receiver and configured to inhibit alerts with severity="info".
