How do I view the Jenkins server console output on the local filesystem?
I'm using the Jenkins Active Directory plug-in and can't log in after several attempts. The error message says: If you are a system administrator and suspect this to be a configuration problem, see the server console output for more details. Where can I find the server console output (on the local filesystem)? I presume that it is accessible from the Jenkins web pages, but since I can't log in, that's not much use. I can log in to the (Windows) server where Jenkins is installed - where are they on the server?
The console output you are looking for are not accessible from Jenkins. If you have installed Jenkins as a service, when that service is started three files are created in JENKINS_HOME: jenkins.err.log, jenkins.out.log, and jenkins.wrapper.log. The relevant ones for you are jenkins.err.log and jenkins.out.log.
If you used the default location you can find them in C:\Program Files (x86)\Jenkins.
In more recent versions you can tail the logs under
$JENKINS_HOME/support/all_[date].log. It outputs all relevant information when you’re modifying settings on the Web console and such.
