The Jenkins Logger Console
The final topic in this chapter is the Logger Console that is built in to the debug versions of Jenkins.
When you start up a local dev instance of Jenkins via Maven (whether through the command line or an IDE), you will notice the additional Logger Console box that is included on the left-hand side of the screen:
Expanding this box will reveal a live log output window, which you can customize in real time to adjust and filter in or out the types and severities of log items that you want to see or hide.
Keeping info selected provides a very verbose level of output, which includes information on mouseover events and other UI interactions. These can be very useful when debugging UI issues.
Unchecking the info box leaves just the warn and error messages. The log output can be managed by pausing and optionally clearing the output and adjusting the filters to suit your need. The following screenshot shows the Logger Console:
