Measure Reference Manual

Busy Counters
Busy counters measure the time a resource is busy. The counter uses a busy or idle state word and
a 64-bit busy-time accumulator to record the cumulative busy time in microseconds.
Units Displayed As...Output Value Is...Attribute Setting
a percentage of the interval lengthPercent of time busy during the
interval.
REPORT RATE is ON.
ms (milliseconds), sec, hr, day, or wkTime busy during the interval.REPORT RATE is OFF.
Time busy expressed in microseconds.REPORT FORMAT is STRUCTURED.
For an example of a busy counter, see the CPU entity counter CPU-BUSY-TIME (page 166).
In H-series and J-series RVUs, there are two types of busy counters:
• BUSY counters, maintained with conventional timers
• TCELLBUSY counters, maintained with timer cells
For an overview of timer cells and related counters, see Timer Cell Counters (page 143).
Elapsed Counters
Elapsed counters measure start-to-finish time for an event.
Units Displayed As...Output Value Is...Attribute Setting
ms, sec, hr, day, or wkAverage elapsed time for each event.REPORT RATE is ON.
ms, sec, hr, day, or wkElapsed time.REPORT RATE is OFF.
Elapsed time expressed in
microseconds.
REPORT FORMAT is STRUCTURED.
For an example of an elapsed counter, see the SQLSTMT entity counter ELAPSED-SORT-TIME
(page 350).
Incrementing Counters
Incrementing counters count events. The counter is advanced each time the event occurs.
Units Displayed As...Output Value Is...Attribute Setting
per-second values: /s, K/s, M/s, G/s,
or T/s
Number of increments for each second
during the time interval.
REPORT RATE is ON.
#, K, M, G, or TNumber of increments during the time
interval.
REPORT RATE is OFF.
Number of increments during the time
interval.
REPORT FORMAT is STRUCTURED.
Measure supports both 32-bit and 64-bit incrementing counters. In G-series RVUs, some incrementing
counters exist in two versions, a 32-bit version and a 64-bit version. The 64-bit version is
distinguished by a counter name ending in the -F. In H-series and J-series RVUs, all counters that
had existed in two versions now exist in only one, 64-bit version. Counter names ending in -F do
not exist in ZMS style but remain available to applications requesting data in legacy style.
For an example of an incrementing counter, see the CLUSTER entity counter MESSAGES
RECEIVED (page 156).
