High CPU Usage Observed on Windows Server from Nov 1st, 9:00 AM Onwards

Answer 1

To troubleshoot high CPU usage observed on your Windows Server, especially since it started at a specific time, you can follow these steps:

1. Identify the Processes: Use Task Manager to check which processes are consuming the most CPU. You can sort the processes by CPU usage to identify the culprit. To access Task Manager, select Start, enter task, and select Task Manager.
2. Use Resource Monitor: For a more detailed view, use Resource Monitor. Open it by selecting Start, entering resmon, and selecting Resource Monitor. Check the CPU tab to see which processes are using the most CPU resources.
3. Check for Patterns: Assess if the high CPU usage correlates with specific tasks or services running at that time. Look for any scheduled tasks or applications that might be running during that period.
4. Collect Performance Data: If the issue persists, consider collecting performance data using Performance Monitor. This can help you analyze CPU usage over time and identify any spikes or patterns.
5. Investigate Third-party Applications: If a third-party application is identified as the cause, contact the vendor for support regarding high CPU usage.
6. Use Debug Diagnostic Tool: If necessary, install the Debug Diagnostic Tool to further analyze the issue, especially if you suspect a specific application or service is causing the problem.

By following these steps, you should be able to identify and address the high CPU usage issue on your Windows Server.

Hi CHATRAGADDA, BAJI BABU (INFOSYS LIMITED Employee)

A sudden CPU spike usually comes from a specific process, scheduled task, or update. Please check Task Manager/Resource Monitor to identify the process, review Windows Update and Task Scheduler around Nov 1, 9:00 AM, and scan Event Viewer for related errors. Also ensure drivers and antivirus tools are up to date, and try a clean boot to rule out conflicts.
