Missing Disk Alarms in DX UIM 23.4 CU6 after upgrade

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

• After upgrading to DX UIM 23.4 CU6, Disk Alarms (e.g., QOS_DISK_USAGE_PERC) are not generated.
• MCS policies appear in plugin_metric.cfg on the target robot, but the alarm field is set to false.
• New MCS policies remain in a PENDING_NEW status indefinitely.
• Alarms may trigger on older versions of the CDM probe (e.g., 7.20) but fail on newer versions (e.g., 8.03).

Environment

• DX Unified Infrastructure Management (UIM) 23.4 CU6
• Robot version 23.4.6
• CDM probe version 8.03 or 8.04
• Monitoring via MCS (Monitoring Configuration Service)

Resolution

To resolve this problem, please alling robot and probe versions as follows:

1. Upgrade Robot: Deploy robot_update-23.4.7.2 to all affected robots.
2. Upgrade CDM: Deploy cdm-8.08 to the target robots.
3. Validate Policy:
   • Open the Alarm Policy in the Operator Console.
   • Ensure the specific condition for the disk alarm is Enabled.
   • Save the policy to trigger a redeployment.
4. Verification: Check the plugin_metric.cfg file (via IM or Admin Console) to confirm that the alarm field for the disk metric is now set to true.
