karugaru / docker_state_exporter Goto Github PK

Hello and thanks for this useful exporter!

We are using it to monitor...the state :) of our containers and have noticed that when it is deployed on a host with ephemeral containers (in our case it is a gitlab-runner), once in a while the exporter exits with message:

{"message":"Error: No such container: 23hg1k34k...

Reading the code, we think that it fails when trying to inspect a container that was just removed (by gitlab-runner).

Though you might get around this by adding a restart policy, it will probably cause alerts to be fired (such as "too-may-restarts" and "prometheus-target-missing").

We could open a PR if you wish though we are not proficient with Go.

Once again thanks for this nice exporter!

Best regards,
Panos

Is there someway to use a TCP/http uri instead of socket?

Hello,

Do you have any grafana dashboard for this metrics ?

Thanks :)
