inactive, but MEASMON keeps the file open until you stop the measurement. To stop
the measurement and close the file, enter the STOP MEASUREMENT command.
If you issue a STATUS MEASSUBSYS command against an aborted measurement,
the measurement is included in the list of active and configured measurements. If you
try to access the active counters of an aborted measurement, an error 3407 is
produced because the measurement is no longer active but is still configured:
MEAS 3407 Invalid measurement number; correct and retry.
MEAS 2000 Comment. For more information type HELP 3407
Message 3407 indicates that MEASCOM passed an invalid measurement number to
the MEASREADACTIVE procedure (the Measure procedure that returns the
information for the LISTACTIVE command). To stop the measurement and close the
data file, enter the STOP MEASUREMENT command.
For more information about MEASREADACTIVE, see Section 6, Creating a Custom
Measurement Application , and the Measure Reference Manual.
For error message descriptions, see the online help or the Measure Reference Manual.
Viewing Reports of Measurement Data
You can view reports of measurement data from active data files, inactive data files, or
active counters. To view a report, you must first make the measurement data file
accessible to MEASCOM by using the ADD MEASUREMENT command.
To use this command, you need read access to the data file, and you might need free
disk space up to three times the size of the data file on the disk containing the data file.
For example, to make the file $PERF.DATA.NOV5 accessible to MEASCOM:
2+ ADD MEASUREMENT $PERF.DATA.NOV5
When you finish with a data file, to stop the MEASFH process and free the disk space
it was using, either:
•
Enter the DELETE MEASUREMENT command to delete access to the file.
•
Exit MEASCOM.
Viewing Reports From Data Files
A measurement data file can contain data from either a currently active or an inactive
measurement. Each MEASCTL process writes counter values to the data file:
•
At the beginning of the measurement
•
When a transient entity starts or stops
•
At each collection interval (if specified)
•
At the end of the measurement
