Issue

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

Environment

• CloudBees CI (CloudBees Core) on modern cloud platforms - Managed Master
• CloudBees CI (CloudBees Core) on modern cloud platforms - Operations Center
• CloudBees CI (CloudBees Core) on traditional platforms - Client Master
• CloudBees CI (CloudBees Core) on traditional platforms - Operations Center
• CloudBees Jenkins Enterprise - Managed Master

• CloudBees Jenkins Distribution

• Disk Usage Plugin

Resolution

If your master 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 Windows master.

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).
