Metric Groups in vSphere
The performance data collection subsystem for vSphere collects performance data on various inventory
items and their devices. Data counters define individual performance metrics. Performance metrics are
organized into logical groups based on the object or object device. Statistics for one or more metrics can
be displayed in a chart.
Table 1‑3. Metric Groups
Metric group Description
Cluster Services Performance statistics for clusters configured by using vSphere Distributed Resource Scheduler, vSphere High
Availability, or both.
CPU CPU utilization per host, virtual machine, resource pool, or compute resource.
Datastore Statistics for datastore utilization.
Disk Disk utilization per host, virtual machine, or datastore. Disk metrics include I/O performance, such as latency and
read/write speeds, and utilization metrics for storage as a finite resource.
Memory Memory utilization per host, virtual machine, resource pool, or compute resource. The value obtained is one of
the following:
n
For virtual machines, memory refers to the guest physical memory. Guest physical memory is the amount of
physical memory presented as a virtual-hardware component to the virtual machine, at creation time, and
made available when the virtual machine is running.
n
For hosts, memory refers to the machine memory. Machine memory is the RAM that is installed on the
hardware that comprises the host.
Network Network utilization for both physical and virtual network interface controllers (NICs) and other network devices.
The virtual switches that support connectivity among all components, such as hosts, virtual machines, VMkernel.
Power Energy usage statistics per host.
Storage Adapter Data traffic statistics per host bus adapter (HBA).
Storage Path Data traffic statistics per path.
System Overall system availability, such as the system heartbeat and uptime. These counters are available directly from
hosts and from vCenter Server.
Virtual Disk Disk utilization and disk performance metrics for virtual machines.
Virtual Flash Virtual flash counters.
Virtual Machine
Operations
Virtual machine power and provisioning operations in a cluster or data center.
vSphere
Replication
Statistics for the virtual machine replication performed by VMware vCenter Site Recovery Manager.
Data Collection Intervals
Collection intervals determine the duration for which statistics are aggregated, calculated, rolled up, and
archived. Together, the collection interval and collection level determine how much statistical data is
gathered and stored in your vCenter Server database.
