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.
