CPU|Capacity Usage (%) | Percent CPU capacity used. Key: cpu|capacity_usagepct_average |
CPU|Usage (%) | Average CPU usage as a percentage. Key: cpu|usage_average |
CPU|CPU Contention (%) | This metric indicates the percentage of time the virtual machines in the ESXi hosts are unable to run because they are contending for access to the physical CPU(s). This is the average number of all VMs. Naturally, the number will be lower than the highest number experienced by the worst hit VM (a VM that suffers the highest CPU contention). Use this metric to verify if the host is able to serve all of its VMs well. When using this metric, ensure the number is within your expectation. The metric is affected by several factors so you need to watch both relative numbers and absolute numbers. Relative means a drastic change in value. This indicates that the ESXi is unable to service its VMs. Absolute means that the real value is high and should be checked. One factor that impacts the CPU contention metric is CPU Power Management. If CPU Power Management clocks down the CPU speed from 3 GHz to 2 GHz that reduction in speed is taken into consideration. This is because the VM is not running at full speed.

Summary Metrics for Host Systems
Summary metrics provide information about overall host system performance.
Metric Name | Description |
---|---|
Summary|Number of Running VMs | This metric shows the number of VMs running on the host during the last metric collection time. Large spikes of running VMs might be a reason for CPU or memory spikes as more resources are used in the host. Number of Running VMs gives you a good indicator of how many requests the ESXi host must juggle. This excludes powered off VMs as they do not impact ESXi performance. A change in this number in your environment can contribute to performance problems. A high number of running VMs in a host also means a higher concentration risk, as all the VMs will become unavailable (or be relocated by HA) if the ESXi crashes. Look for any correlation between spikes in the number of running VMs and spikes in other metrics such as CPU Contention/Memory Contention. Key: summary|number_running_vms |
Summary|Maximum Number of VMs | Maximum number of virtual machines Key: summary|max_number_vms |
Summary|Number of vMotions | This metric shows the number of vMotions that occurred in the host in the last X minutes. The number of vMotions is a good indicator of stability. In a healthy environment, this number should be stable and relatively low. Look for correlation between vMotions and spikes in other metrics such as CPU/Memory contention. The vMotion should not create any spikes, however, the VMs moved into the host might create spikes in memory usage, contention and CPU demand and contention. Key: summary|number_vmotion |
Summary|Total Number of Datastores | Total Number of Datastores. Key: summary|total_number_datastores |
Summary|Number of VCPUs on Powered On VMs | Total number of VCPUs of Virtual Machines that are powered on. Key: summary|number_running_vcpus |
Summary|Total Number of VMs | Total number of virtual machines.
Note: This is the total number of VMs excluding VM templates.
Key: summary|total_number_vms |
Summary|Number of VM Templates | Number of VM Templates Key: summary|number_vm_templates |
Summary|Consider for Balance | Summary|Consider for Balance = 1 when the host is Powered On, Connected, not in Maintenance Mode, and not a Failover Host, otherwise it = -1 |
