Performance Counters for CPU Usage

This table contains the values for each category of the counters that measure CPU performance.

GROUP NAME: cpu

Counter Name Category Value
usage
unit Percentage, precision to 1/100 percentage point, so 1 = 0.01%. A value between 0 and 10000.
description CPU usage as a percentage over the interval of collection.
statistic type rate
rollup type average, minimum, maximum
entity host, virtual machine
usagemhz
unit MHz
description CPU usage in MHz over the interval of collection.
statistic type rate
rollup type average, minimum, maximum
entity host, virtual machine, compute resources, and resource pools
system
unit millisecond
description CPU time spent on system processes.
statistic type delta
rollup type summation
entity virtual machine (per cpu instance only)
wait
unit millisecond
description CPU time spent on wait state.
statistic type delta
rollup type summation
entity virtual machine (per cpu instance only)
ready
unit millisecond
description CPU time spent on ready state.
statistic type delta
rollup type summation
entity virtual machine (per cpu instance only)
extra
unit millisecond
description CPU time that is extra.
statistic type delta
rollup type summation
entity virtual machine (per cpu instance only)
used
unit millisecond
description CPU time that is used.
statistic type delta
rollup type summation
entity virtual machine (per cpu instance only)
guaranteed
unit millisecond
description CPU time that is guaranteed for the virtual machine
statistic type delta
rollup type summation
entity virtual machine (per cpu instance only)
reservedCapacity
unit MHz
description The value of the reservation property of the host's resource pool, or the sum of the reservation properties of the resource pool's (immediate) children, whichever is larger. Note that children's sum of reservations can be larger than that of the parent only if the parent is marked as reservationExpandable.
statistic type absolute
rollup type average
entity host
