Number of running hosts that are powered on. Kernel per command.Īverage time spent in ESX host VM Kernel per read.Īverage time spent in ESX Server VM Kernel per write. Total latency is the sum of kernel latency and device latency.Īverage time spent in ESX Server V. This metric shows the average amount of time for a write operation to the datastore. This metric is the sum of the Kernel Disk Read Latency and Physical Device Read Latency metrics. This metric shows the average time taken for a read from the perspective of a guest operating system. This metric is the sum of Kernel Latency and Physical Device Latency metrics. This metric shows the average time taken for a command from the perspective of a guest operating system. This metric shows the number of disk commands issued in the performance interval. This metric shows the number of disk commands canceled in the performance interval. This metric shows the number of bus resets in the performance interval.

If you have more than 50% free storage space, you are not utilizing your storage in the best possible way.ĭevice metrics provide information about device performance. Less than this, and you might experience problems when a snapshot is not deleted. When using this metric, verify that you have at least 20% of free storage. Use this metric to know the percentage of storage space being used on the datastore. This metric shows the amount of storage that is being used on the datastore.Ĭapacity|Total Provisioned Consumer Space A best practice is to use 5 TB for VMFS and more for vSAN. Ensure that the size can handle enough virtual machines to avoid datastore sprawl. VMFS datastore size has grown over the years as virtualization matures and larger virtual machines are now onboard. Typically the size of the datastore should not be too small. Use this metric to know the total capacity of the datastore.

This metric shows the overall size of the datastore. Use this metric to know how much storage space is being used on the datastore.Ĭheck the metric trend to identify spikes or abnormal growth. This metric shows the amount of storage that was allocated to the virtual machines.

The exact size of the datastore is based on company policy. Try to avoid having too little free disk space in order to accommodate unexpected storage growth on the datastore. Use this metric to know how much storage space is unused on the datastore. This metric shows the amount of free space that a datastore has available. Capacity Metrics for DatastoresĬapacity metrics provide information about datastore capacity. See Capacity Analytics Generated Metrics. VRealize Operations Manager collects capacity, device, and summary metrics for datastore objects.Ĭapacity metrics can be calculated for datastore objects.
