Table 1‑50. CPU Usage Metrics for Cluster Compute Resources (Continued)
Metric Key Metric Name Description
cpu|host_workload_disparity Host workload Max-Min
Disparity
Dierence of Max and Min host workload in the
container.
cpu|host_stress_disparity Host stress Max-Min
Disparity
Dierence of Max and Min host stress in the
container.
Disk Metrics for Cluster Compute Resources
Disk metrics provide information about disk use.
Table 1‑51. Disk Metrics for Cluster Compute Resources
Metric Key Metric Name Description
disk|commandsAveraged_average Commands per second Average number of commands issued per
second during the collection interval.
disk|totalLatency_average Disk Command Latency (ms) Average amount of time taken for a
command from the perspective of the guest
operating system. This metric is the sum of
the Kernel Command Latency and Physical
Device Command Latency metrics.
disk|totalReadLatency_average Disk Read Latency Average amount of time for a read operation
from the virtual disk. The total latency is the
sum of Kernel latency and device latency.
disk|totalWriteLatency_average Disk Write Latency The average amount of time taken for a read
from the perspective of a Guest OS. This is
the sum of Kernel Read Latency and Physical
Device Read Latency.
disk|numberRead_summation Read Rate (KBps) Number of times data was read from the disk
in the dened interval.
disk|numberReadAveraged_average Reads per second Average number of read commands issued
per second during the collection interval.
disk|usage_average Usage Rate (KBps) Average of the sum of the data read and
wrien for all of the disk instances of the host
or virtual machine.
disk|numberWrite_summation Write Rate (KBps) Number of times data was wrien to disk
during the collection interval.
disk|numberWriteAveraged_average Writes per second Average number of write commands issued
per second during the collection interval.
disk|read_average Read Requests Amount of data read from the disk during the
collection interval.
disk|write_average Write Requests Amount of data wrien to the disk during the
collection interval.
disk|commands_summation Commands Issued Number of disk commands issued during the
collection interval.
disk|sum_queued_oio Total Queued Outstanding
operations
Sum of queued operation and outstanding
operations.
disk|max_observed Max Observed OIO Max observed outstanding IO for a disk.
Memory Metrics for Cluster Compute Resources
