Feature Request

I have looked (and tried to implement) https://support.cloudbees.com/hc/en-us/articles/115002626172-Configure-Loggers-for-Jenkins?page=42 and couldn't get it to work. I also think adding this to JCasC would offer a better experience:

We run Jenkins as a container and the above means we need to rebuild (or at least restart) the container if we make a change. Adding this to JCasC would mean we only need to reload the config.

It's this which is tracked on the jenkins issue tracker: https://github.com/jenkinsci/jenkins/pull/4538

will try resolve conflicts when I get a chance

Ahh, sorry, didn't think to check there 😳

Resolved and build back to green and tests passing, hopefully it gets merged this time.

partially related, I'm unable to determine precisely how to alter the default system log level through JCasC: i.e winstone to WARNING

[timja]

That's a different feature and it may not be supported currently, generally you shouldn't want to change the default level and should create a log recorder instead

thanks for the quick response! got it, but, by creating another log creator for both winstone org.apache.sshd, which one will take precedence: the default log recorder or the custom log recorder?

[timja]

the custom log recorder will record everything that you set it to, it will go to that log recorder and not the system log
