Issue/Introduction

We are observing inconsistent disk utilization (QOS_DISK_USAGE_PERC) data for a device.

The /boot  threshold value is 40% now, but the metrics are showing a high utilization value, while the corresponding graph displays a lower utilization.

Environment

• DX UIM 23.4 CU3

Resolution

• Use cdm v8.03 and cdm_mcs_templates v7.22
• Upgrade the robot ->robot_update-23.4.4.1

1. "Set QoS to robot name instead of computer hostname" as this option in the controller should help. In robot.cfg the raw config setting just for reference is: set_qos_source = yes
   Then it should just ignore the hosts/DNS and use the defined robot name.
2. Make sure the robotname =  is NOT set blank.
3. Then make sure the cdm probe on those robots has this option enabled:
4. "Allow QoS source as target"
5. Select the controller probe and press Ctrl-P to open the probe utility.
6. Then click the cogwheel to select Expert Mode
7. Clear the niscache and reset the robot dev id using the controller callbacks.
