Hi,
I am trying to create an alert for stopped containers.
If I am using the exact container name I have no problem:
-* alert: ContainerKilled*
* expr: absent(container_start_time_seconds{name="be-dev-4"})*
* for: 15m*
* labels:*
* severity: 'warning'*
* annotations:*
* summary: 'Container killed'*
* description: 'A container{{ $labels.name }} has disappeared'*
However, if i am trying to use regexp for the container name (as I have a
few containers with this suffix) , then it fails whatever I try -
If I use this, then no alert is sent:
* - alert: ContainerKilled*
* expr: absent(container_start_time_seconds{** name=~".*dev-4"})*
* for: 15m*
* labels:*
* severity: 'warning'*
* annotations:*
* summary: 'Container killed'*
* description: 'A container{{ $labels.name }} has disappeared'*
If I use this, then alert is sent, but without the stopped container name:
- alert: ContainerKilled2
expr: absent(container_start_time_seconds{*name=~".*dev-4"}*)
for: 15m
labels:
severity: 'warning'
annotations:
summary: 'Container killed'
*description: 'A container has disappeared {{ $labels.instance }} of
job {{ $labels.job }}'*
Any idea how to alert then with a regexp, *and *the container name?
Thanks
