Issue/Introduction

Environment

Component:

Resolution

The CDM probe on Linux does not make use of the free command
The probe primarily uses the output from /proc/meminfo command to calculate the memory usage.

There are factors that may affect the values being seen. See the cdm Advanced Configuration section under the cdm probe documentation 
for information on those and Raw Configuration keys that can be set.

The cdm probe loglevel can also be set to Level 5 which will then show the values the probe has obtained in the messages
prefixed cdm: (GetMemoryInfo)
These can then be compared to the actual values from the Linux server via the cat /proc/meminfo command to confirm that the probe
is reporting the correct values.
