Qube produces a number of different log files, each serving a different purpose. These log files may be stored locally, on a shared file system or both. The log files are an important means to troubleshoot problems, and they serve to document executed jobs.
Consideration should be taken to make sure you have enough capacity to properly store logs. During the course of normal operation, the Supervisor will produce extensive logs of its activities. By default, these logs are stored in a single file on the Supervisor host called supelog. On each Worker, a similar log file is produced in workerlog.
For each job, a numbered directory is created corresponding to each job ID. Inside this directory a number of different log files are created containing the history of the job and subjobs, the output from all subjobs, and an archive of the job itself. This is referred to as the joblog. This directory and associated log files are created jointly by the Supervisor and the Worker and the Supervisor relays the contents of the logs to various client commands, so they need to be shared in some way.
