Jenkins is one of the important CI tools which many organization used as part of their Build and DevOps infrastructure. I am going to consolidate all the troubleshooting techniques which can be used in order to find any issues related in Jenkins.
Step 1. Take a look at Log generated by the Jenkins and plugins via http://jenkins-master/log
Note: Here you can also create your own logger and and set your custom log levels such as (severe, warning, info, config, file, finer, finest, all)
Step 2. Also, you can look at /var/log/jenkins/jenkins.log via doing "tail -f /var/log/jenkins/jenkins.log" and check carefully whats breaking it.
