I am removing WIP, I think it is ready to go, but it should be reviewed by testing locally

[kstaken]

Is the N/A here intentional?

curl  localhost:5678/txt/controllers
name            job_id                                workers_available  workers_active  failed  queued  processed
--------------  ------------------------------------  -----------------  --------------  ------  ------  ---------
Data Generator  7ab049eb-0a0f-42ff-be5c-cf979c2b0f5c  1                  N/A             N/A     1       57

[peterdemartini]

@kstaken yes, and no, instead of having a blank value, we put 'N/A' to indicate that this value doesn't exist since applying default values. But your example should show zeros, I will fix that

[godber]

@kstaken since you have it up and running can you share the output of

curl -Ss -H "Accept: blah application/openmetrics-text; blah" localhost:5678/cluster/stats

here?

Looks good, thanks @kstaken

Stopping on ex seemed to work but using jobs does this and does not stop.

curl -XPOST localhost:5678/jobs/c9fbc8ec-8d21-4f03-936d-53e72c18b505/_stop
{
    "status": "terminated"
}

[kstaken]

That is reporting correct however the job_id I was using was retrieved using /txt/jobs?size=1 which gave me an old job. Appears the default sorting has been lost.

[kstaken]

Using the correct job_id stop works fine but /txt/jobs should give you newest jobs first.

[kstaken]

This seems good.
