DiskSpace Monitor shows false positive in support bundles

Issue Type:	Bug
Assignee:	Allan BURDAJEWICZ
Components:	core
Created:	2019-09-16 00:51
Environment:	core:2.190 support-core:2.61
Priority:	Minor
Reporter:	Allan BURDAJEWICZ

Generated support bundle shows false positive in the node-monitors.md. For example for a node that is totally fine and has a lot of free space under the configured threshold, the file shows:

 
                                                                Free Disk Space
----
 - Is Ignored: false
 - Threshold: 1GB
 - Computers:
   * master: Disk space is too low. Only 3.654GB left on /var/jenkins_home.
[...]
Free Temp Space
----
 - Is Ignored: false
 - Threshold: 1GB
 - Computers:
   * master: Disk space is too low. Only 91.151GB left on /tmp.
 
                                                            

The UI does not show the problem, the toHtml(): https://github.com/jenkinsci/jenkins/blob/stable-2.190/core/src/main/java/hudson/node_monitors/DiskSpaceMonitorDescriptor.java#L104-L113
This is only distinguishable when using toString(): https://github.com/jenkinsci/jenkins/blob/stable-2.190/core/src/main/java/hudson/node_monitors/DiskSpaceMonitorDescriptor.java#L74
