vCenter is the key object for monitoring and reporting as it is the key building block in a VCF environment. Diagnostics helps you with that task and adds value by providing data for reachability, utilization, and services that you cannot derive from legacy tools.
In the Utilization screen, Diagnostics measures thresholds for CPU, memory, disk, and database space use, so you can easily identify issues that might result from a memory leak or a scalability issue, and to proactively resolve issues before they occur.
CPU Utilization - If vCenter Server Appliance CPU Utilization consistently exceeds 85% of the appliances CPU Capacity, check recommendations for next steps. Review findings for known issues, and the KB links below for specific issues and general troubleshooting steps.
CPU Memory - If vCenter Server Appliance Memory usage consistently exceeds 85% of the appliances memory size, check recommendations for next steps. Review findings for known issues, and the KB links below for specific issues and general troubleshooting steps.
