Viewing Reports From Active Counters
Identifying Active Measurements
To list currently active measurements, enter the STATUS MEASSUBSYS command:
10+ STATUS MEASSUBSYS
Number of Active (or Configured) Measurements = 1
$PERF.DATA.FILCPU
To list the configuration of an active measurement, enter the ADD MEASUREMENT
command to make the measurement available to MEASCOM and the INFO
MEASUREMENT command to display the configuration:
11+ ADD MEASUREMENT $PERF.DATA.FILCPU
12+ INFO MEASUREMENT $PERF.DATA.FILCPU
Add measurement $PERF.DATA.FILCPU -- Current Data File --
Data collected from system \HATI, MEASURE release version G10
From 5 Apr 2003, 17:15:10, Interval 30 Minutes
-- Add Cpu *
-- Add File $MYVOL.MYSUBVOL.*
Using the LISTACTIVE entity-type Command
To examine currently active counters, enter the LISTACTIVE entity-type command.
The format and output of this command are similar to those of the LIST entity-type
command. However, the LISTACTIVE entity-type command displays data for only
one entity at a time.
You must specify a unique entity in the LISTACTIVE command because each
MEASCTL process uses the entity specification to locate the active counter record in
system counter space. In this example, the CPU, PIN, and file number (0,38,1)
uniquely identify the open of the user ID file.
13+ LISTACTIVE FILE * (0,38,1)
File Open $SYSTEM.SYSTEM.USERID
Opener 0,38 ($TMP) Program $SYSTEM.SYSTEM.TRANSACT File Num 1

You can use the FOR clause of the LISTACTIVE command to define a specific
timeframe for monitoring. For example, this command displays counter values for CPU
Note. The LISTACTIVE entity-type command cannot be used to read active counters for
DISCOPEN or PROCESSH entities. If you specified a collection interval, you can read data for
these entities in an active data file by using either the LIST
entity-type or the LISTALL
entity-type command. If you did not specify a collection interval, you cannot view the data
until the measurement stops.
