+### Understand the alert
+
+The `vsphere_cpu_usage` alert monitors the average CPU utilization of virtual machines in the vSphere platform. 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.
