Shell Executor Prometheus metrics: calculating % of failed jobs should be easy

[atmosx]

Is your feature request related to a problem? Please describe.

I’m trying to create a Grafana dashboard based on the shell executor metrics. One of the graphs is meant to calculate the percentage of failed jobs over a specific time frame or from the start of tracking.

The dkron_job_execution_done_count metric is a counter. A common approach is to filter by a specific label versus all entries of the same metric. This can be achieved by adding exit_code as a label to dkron_job_execution_done_count. Since it’s a low cardinality metric, adding this label should not pose any issues.

Describe the solution you'd like
Add exit_code to dkron_job_execution_done_count.

Describe alternatives you've considered
None.
