Reporting on rule usage snapshots
Pega Platform maintains statistics about the number of rule executions since startup. Create and view reports about these shutdown statistics to understand which rules execute most often, and which execute rarely or not at all. Viewing these statistics can help you identify the causes of variations in system performance.
The system holds these statistics as property values in the
Log-RuleUsage class, with additional detail in the
Log-RuleUsage-Details class. In the normal table mapping, the
system saves these statistics a row of the pr4_log_usage and
pr4_log_rule_usage tables. For a description of the properties
in these classes, see Rule usage snapshots.
