How does MeasureWare log performance data?
MeasureWare logs all performance data in the /var/opt/perf/datafiles directory. The log files located here are used to store all performance data logged by MeasureWare.
/var/opt/perf/datafiles/logappl The file that MeasureWare uses to store all application data.
/var/opt/perf/datafiles/logindx The file that MeasureWare uses to record instance names of transaction and device data.
/var/opt/perf/datafiles/logdev The file that MeasureWare uses to log disk and logical volume data.
/var/opt/perf/datafiles/logproc The file that MeasureWare uses to log process data.
/var/opt/perf/datafiles/logglob The file that MeasureWare uses to log Global metrics.
/var/opt/perf/datafiles/logtran The file that MeasureWare uses to log Transaction (ARM) data.
Note: The minimum configurable logfile size is 1.0 Mb. Log files can be resized through the utility command.
The /var/opt/perf/parm file contains the size configurations that scope uses to manage the logfile sizes: size global equals 10 application equals 10.0 process equals 20.0 transaction equals 10.0 device equals 10.0
The size values represent megabytes. Adding these values together will allow you to compute the approximate maximum amount of disk space that will be required for the scope logfiles. In this example 60mb minimum disk space in /var/opt/perf/datafiles directory would be required to store all the logfiles.
Note: The /var/opt/perf/datafiles directory can be it's own separate file system from /var to prevent /var to filling up. On NT platforms the default datafiles directory is located in C:\rpmtools\data\datafiles. MeasureWare and all other performance tools must be uninstalled in order to change the location of the datafiles directory
