Table 1‑3. Metric Groups (Continued)
Metric group Description
Network Network utilization for both physical and virtual network interface controllers (NICs) and other
network devices, such as the virtual switches that support connectivity among all components, such as
hosts, virtual machines, VMkernel, and so on.
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 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 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.
Table 1‑4. Collection Intervals
Collection
Interval/Archive
Length
Collection
Frequency Default Behavior
1 Day 5 Minutes Real-time statistics are rolled up to create one data point every 5 minutes.
The result is 12 data points every hour and 288 data points every day. After
30 minutes, the six data points collected are aggregated and rolled up as a
data point for the 1 Week time range.
You can change the interval duration and archive length of the 1 Day
collection interval by configuring the statistics settings.
1 Week 30 Minutes 1 Day statistics are rolled up to create one data point every 30 minutes. The
result is 48 data points every day and 336 data points every week. Every 2
hours, the 12 data points collected are aggregated and rolled up as a data
point for the 1 Month time range.
You cannot change the default settings of the 1 Week collection interval.
1 Month 2 Hours 1 Week statistics are rolled up to create one data point every 2 hours. The
result is 12 data points every day and 360 data points every month
(assuming a 30-day month). After 24 hours, the 12 data points collected are
aggregated and rolled up as a data point for the 1 Year time range.
You cannot change the default settings of the 1 Month collection interval.
1 Year 1 Day 1 Month statistics are rolled up to create one data point every day. The
result is 365 data points each year.
You can change the archive length of the 1 Year collection interval by
configuring the statistics settings.
NOTE If you change the duration of data collection intervals you might need to allocate more storage
resources.
