The alert is triggered in a warning state when the CPU utilization is between 75-85% and in a critical state when it is between 85-95%. + +### What does high CPU usage mean? + +High CPU usage indicates that the virtual machine's CPU resources are being heavily utilized. This can lead to performance issues, slow response times, and decreased stability. + +### Troubleshoot the alert + +1. Confirm the high CPU usage by logging into the vSphere management console and checking the CPU performance metrics for the affected virtual machine(s). + +2. Identify the cause of high CPU usage: + + - Check the virtual machine's running processes to identify any resource-intensive applications or services. You can use the `top` command on Linux-based virtual machines or Task Manager on Windows-based virtual machines. + - Inspect application logs and system logs for any signs of issues, errors, or crashes that could be contributing to high CPU usage. + - Verify if the virtual machine has adequate CPU resources allocated. If the virtual machine is consistently using a high percentage of its allocated CPU resources, consider increasing the allocated CPU resources. + +3. Remediate the issue: + + - If an application or service is responsible for the high CPU usage, try restarting it or addressing the specific issue causing the problem. + - If the virtual machine is consistently using a high percentage of its allocated CPU resources, consider increasing the allocated CPU resources or optimizing the virtual machine's performance through application and OS tuning. + - Monitor the CPU usage after making changes to ensure that the issue has been resolved. + +### Useful resources + +1.
