Issue/Introduction

The cdm probe is configured to collect Disk Throughput metrics, but no metrics are collected by the probe on Linux Red Hat robots.
The cdm probe at loglevel 5 do not show that the CheckDiskUtil function is ever called.  This is the function responsible for collecting the Disk Throughput metrics.

What command does the cdm probe use to collect Disk Throughput metrics on Linux ssyteme?

Environment

UIM Server:  Any version
cdm probe:  6.30 version through current GA version 6.42
Linux RHEL robot

Resolution

The cdm probe initially makes the following call to determine Disk Throughput metrics:

fdisk -l | awk '/Disk/{print$2}'

If the UIM robot is not owned by the root user, then the user that owns the robot and the cdm probe must have system permissions that allow the user to execute this command.  If these permissions are not granted to this user, the cdm probe will not collect the Disk Throughput metrics.
