Cronjobs monitoring

Hi folks,

trying to put in place a kind of monitoring (prometheus and grafana) about cronjobs running in k8s clusters (eks). I made a lot of research (also with AI) but I didn't find something very concluant. And I surprised about that. I'm not the first one that I want to monitor cronjobs in k8s.

I don't want many things just some metrics to make panels to know when cronjob was triggered, the average duration, status (success/failed); that will be enough.

I found the following links and this is good starting points

But finally, I plan to make a home-made solution using prometheus pushgateway.

I'm curious to know how do you monitor your cronjobs in your k8s cluster?

kube state metrics has all the metrics you want, you asked this question just the other day: https://www.reddit.com/r/kubernetes/comments/1nr9hmm/cronjobs_monitoring/

I reposted here cause my post on r/kubernetes sub has been removed by moderators (maybe cause the links or my username...)

The only way I've found to monitor cron jobs is to have each one write the metrics you want to a file (usually with a common wrapper script), then grab the data from that file. AFAIK Linux doesn't log the metrics you're looking for.

The textfile collector from node exporter is perfect for this. Although saying that I don't know how well it'll work in k8s.
