Jenkins is now updated to the latest LTS, as well as all plugins.
Since this update the monitoring has been flapping. Every now and then there’s a warning in the Apache log that it can’t connect to the Jenkins service. I’ll take a look at why this is.
Today I’ve removed various unused plugins (Remove unused Jenkins plugins · theforeman/foreman-infra@446918d · GitHub) and applied all available updates to Jenkins plugins. Let’s see if it helps.
I think it helped, because I don’t see it flapping anymore. Or it felt threatened by Jenkins migration on 2023-03-23 and decided to behave.
