How to export Job execution metrics in Prometheus

Hi, my name is Aleksei,

I am looking to export job wide metrics in Prometheus, such as job execution time. it would be helpful to track Week over Week execution time of jobs (e.g. lint, build, etc). I have not find any existing exporters yet. For now, My naive solution is to grep gitlab logs and scrape executed jobs information using fluentd. That approach seems tricky.
Is there existing projects to export job wide metrics?

p.s.: I found only 2 pages useful, but they won’t solve my problem:

Thank you in advance!

Best regards,
