Issue/Introduction

MCS Profiles deployed with Alarm policies and TOT enabled auto close alarms even though their threshold is in violation, and causes a scenario where an alarm is opened on the next poll.

Environment

• DX UIM 23.4 CU3, CU4 and CU5
• Robot: version 23.4.3, 23.4.4 and 23.4.5
• mon_config_service (MCS)
• nas 23.4.4
• spooler

Cause

• TOT not working consistently on generating alarms
• spooler (plugin_metric)

Resolution

1.  Download and import plugin_metric-23.4.4.1-20250814.103459-12.zip into the UIM Archive (see attached).

2.  Distribute the plugin_metric-23.4.4.1 package to the target robot.

   ⚠️ Note: Installation will trigger an automatic restart of the robot service. Ensure a maintenance window is active if required.

3.  Monitor TOT alarms to confirm the fix is active and the system remains stable.

A permanent fix is integrated into Robot version 23.4.6 (CU6) and all subsequent releases.
