System Metrics REST API BusyValues Incomplete.

Issue/Introduction

The System Metrics REST API endpoint (metrics?type=BusyValues) returns incomplete data across multiple Automation Engine (AE) versions. The missing metrics lead to inconsistent results that can affect forecasting, monitoring accuracy, and system performance insights.

Specific symptoms vary depending on the version:

• In AE v24.4.1: The endpoint successfully returns WP and CP BusyValues. However, JCP and REST BusyValues are missing entirely, even when the REST process is active.

• In AE v24.4.3 (including Kubernetes Edition): The endpoint returns empty values for all CP-related processes. This means normal CP, JCP, and REST BusyValues are completely missing.

• Steps to Reproduce

  1. Set PERFORMANCE_ACTIVE = Y in the UC_SYSTEM_SETTINGS variable.

  2. Execute the following REST API call (replace <hostname>, <port>, and <client_id> with your environment details):

     https://<hostname>:<port>/ae/api/v1/<client_id>/system/metrics?type=BusyValues

  3. Compare the returned metrics for the WP, CP, JCP, and REST processes.
