Disk Usage Plugin causing high CPU

Issue

The original Disk Usage plugin offers many features, however it consumes many resources and in some instances can prevent the Jenkins controller from operating correctly.

Disk Usage Plugin

Resolution

If your controller is running on an Unix based system, stop using the Disk Usage Plugin and use the CloudBees Simple Disk Usage Plugin instead which offers less options but is performances oriented. This plugin won’t work on a controller running on Windows.

Workaround

Continue using the Disk Usage Plugin keeping in mind the increased CPU usage during the time frame it takes for it to run (it runs each 60 minutes).
