Microsoft Monitoring Agent – High CPU Utilization

Unveiling the Potential Culprit: Microsoft Monitoring Agent’s Surging CPU Usage

Understanding High CPU Usage of Microsoft Monitoring Agent

High CPU usage of the Microsoft Monitoring Agent can cause system performance issues. To troubleshoot and resolve this, follow these steps:

1. Identify the host with the high CPU usage by using the Task Manager or Resource Monitor.
2. Check if the high CPU usage is due to agent processes by looking for “MonitoringHost.exe” or “HealthService.exe”.
3. Verify the version of the agent and make sure it is up-to-date.
4. Check if the high CPU usage is caused by a specific process or script running on the host.
5. Review the agent configuration and adjust the sampling frequency if necessary.
6. Check for any issues with dependencies, such as Operations Manager agent processes or SQL Cluster Hosts.
7. Monitor the CPU utilization using the System Center Operations Manager (SCOM) and Azure Monitor.
8. Analyze the collected data in Azure Log Analytics workspace or other monitoring tools.
9. Consider optimizing the agent cache and workflows to reduce CPU usage.
10. If the high CPU usage persists, consult Microsoft support or visit the provided link for further assistance.
