Using the full details display of Performance Analyzer

Version:

Only available versions of this content are shown in the dropdown

The Full, Init, and Delta links in the Performance Analyzer (PAL) provide detailed data about a single row of the display. The scope of information on this window depends on which link you clicked on the Performance report.

  • Full link – Statistics reflect all activity since you signed on or clicked Reset.
  • Init link – Statistics reflect activity at the time you most recently started the Performance tool, but not activity since that time.
  • Delta link – Statistics reflect only incremental values between adjacent rows of the Performance report.
Hold the mouse pointer over a statistic to view tooltip text.

The number of decimal places in timing results depends on the hardware and software supporting Pega Platform. In general, the decimal places reported are significant. Per-requestor CPU statistics are not available for UNIX platforms. The value NaN (Not a Number) indicates a numeric exception, such as dividing a number by zero, or by a small value close to zero, and attempting to compute the square root of a negative number.

All performance statistics are property values on a clipboard page of the Code-Pega-PAL class.

Node Summary

Storage Stream values — values of columns named pzPVStream — have one of three formats ( V4 , V5 , and V6 ). A setting in the prconfig.xml file or Dynamic system Settings determines which format the system uses when it saves a Storage Stream. Your system may contain a mixture of formats, even in a single table, because the setting takes effect on a row-by-row basis.

For example, if you open an instance (a row) containing a Storage Stream in Version 4 format, update the instance, and save the instance, the system saves Storage Stream in the current format, typically Version 6.

The Instances Read counts do not include Storage Stream instances read from the rule cache.
