As FME Server processes jobs, the history of these jobs is stored as records in the repository database and as log files in the file system. Eventually, the volume of these records and logs can build up and cause issues, such as slow web interface response time and low disk space. Therefore, FME Server ships with two workspaces that you can scheduled to purge job history from the database and log files from the file system.
To enable scheduled purging:
Log into the Web User Interface:
http://<host>/fmeserver
To enable job history purging, select the Purge_Jobs schedule and click Enable.
By default these schedules are configured to run once per day.
