Example: Peak percentile

A sample Report Form is provided to help you format a Performance Summary report with a distribution of response time using peak percentiles. This can be useful for monitoring service level compliance.
RESPPEAK
Response Time Peak Percentiles

You can edit the sample form, change it and SAVEAS to create a new form to tailor the report to the needs of your analysis.

For example, modify RESPPEAK by overtyping the first four RESPONSE fields with the field names CPU, SUSPEND, DISPATCH, and DISPWAIT, and change the function of the next RESPONSE field from 75 to MIN (minimum), then SAVEAS PEAKPERC.
