Performance Meter Display and Sample Intervals

You can change the Sample Time (the frequency that the meters are updated) and the units measured by the hour and minute hands on the dial display with the Sample time, Hour hand, and Minute hand settings. The default is for the hour hand to show a sample over a 20-second interval and the minute hand the average over a 2-second interval. If you change the values in these fields, remember to click SELECT on the Apply or Set Default button to record the changes.

If you'd like to save and examine individual samples, check the Log Samples checkbox on the Properties window. This activates the Filename text field. Samples are saved in the file typed in the Filename text field. If no file name is specified, samples are saved in a file in your home directory called perfmeter.logXXX, where XXX is replaced by a unique identifier.

Do not specify the same file name for more than one Performance Meter at the same time. Either specify a different file name for each sample file, or do not specify any file name at all and let the Performance Meter construct unique file names.

Do not leave the Performance Meter running for a long time with Log Samples on. The file with the samples will keep getting larger until your system runs out of disk space on the file's partition.
