Issue:
On a new RHEL7 server the cdm probe isn't reporting changes in disk usage. 
I am configuring the warning to alarm at 95% disk free which is beyond the threshold but no alarm is generated.

Cause:
Probe was configured for MB not % and thus the threshold was 95MB free not 95%.

This threshold was below the actual MB free and thus no alarm was generated
Resolution:
Configure the probe to monitor %free rather than MB
