Hey Ludo,

I added this line, and they sadly do not overlap :(

Yes as soon as those evaluations will be repaired, we should be able to
compute those metrics. I chose to keep the error messages as a
remainder.

I added various other metrics and updated the "/metrics" page. Once we
have a better view, we should think of adding thresholds on those
metrics.

Closing this one!

Thanks,

Mathieu

As discussed earlier today on IRC with Clément, we could add performance
monitoring capabilities to Cuirass.  Interesting metrics would be:

  • time of push to time of evaluation completion;

  • time of evaluation completion to time of build completion.

We could visualize that per job over time.  Perhaps these are also stats
that ‘guix weather’ could display.
