C-1823The Full, Init, and
Delta links of the Performance report (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 Process Commander. In
general, the decimal places reported are significant. Per-requestor CPU
statistics are not available for UNIX platforms. R-14873 The
value NaN indicates a divide-by-zero or other numeric
exception.
All performance statistics are property values on a
clipboard page of the Code-Pega-PAL class.

The header area at the top of the display contains these

Rule Execution
Counts
Statistics in this area report how many times rules of various
categories were executed for this requestor. Only rules of rule types
subject to rules assembly — that is, rules converted to Java
— are counted.
Counts increment when an operation starts, not when it ends.
These statistics are summarized across all requestor sessions in
the shutdown report. See Working with
the shutdown Rule Usage facility.

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 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 V4 format, update the instance, and save the instance, the
system saves Storage Stream in the current format, typically V6.
The Instances Read counts do not include Storage
Stream instances read from the rule cache.

Reporting on
Performance Details
The system captures performance details for interactive users at
the interaction level, but this data is not retained.
The system also captures performance details for each requestor
once each hour and also at sign-off. The usage daemon saves these
details as instances of the Log-Usage class. You can report on these
details using SQL reporting tools and the pr_perf_stats
database table. See How
to analyze system-wide usage with the Log Usage class.
