I've found 'below' (in Fedora repo) very useful in tracking down processes that are contributing to memory, cpu, or io pressure - using cgroups accounting. It's possible to zoom in on a cgroup, see individual processes, their memory, io, cpu and swap activity. Pressure (PSI) is useful because it results in latencies, potentially everywhere else. So when you suspect bad behavior in your app, it might be because something else is soaking resources. Your app might be legitimately putting memory or cpu or io pressure on the system, that's the primary purpose of the setup, to service that app. So it can sometimes be difficult to figure out whether your app's resource requirements are reasonable/normal or if it's run away. -- Chris Murphy _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
