Log and miscellaneous tables

Nine tables can store instances of Log- classes. The key to these instances contains a date and time in UTC format.

Table	Description
pr_perf_stats	Holds instances of the Log-Usage class. See Analyzing System-wide usage with the Log-Usage table.
pr_daily_usagepr_hourly_usage pr_license_parameters pr_usage_summary	Support the License Compliance facility. See Working with the License Compliance facility. Select> System >Tools > Usage Metrics to report on the pr_usage_summary table. PROJ-532
pr4_log_rule_usage	Holds statistics collected during system shutdown about cumulative rule execution statistics. Associated with the Log-RuleUsage class. C-2707 See Working with the shutdown rule usage facility.
pr4_log_rule_usage_details	Corresponds to the Log-RuleUsage-Details class. Holds details of a daily snapshot of the rules assembly cache, which the system can scan later at the next system startup to pre-populate the rules assembly cache. See Working with the rules assembly cache. PROJ-454
pr_log_dataaccessaudit	Corresponds to the Log-DataAccessAudit class. When configured in harness rules and flow action rules, holds the details for each operator's use of those rules. See Flow Action form — Completing the Security tab. 5.5 GRP-245
pr_log	Holds instances of concrete classes derived from the Log- base class, other than those in the above tables.

The Pega-RULES agent normally runs the standard Code-.SystemCleaner activity once each day for housekeeping tasks, including purging older records (instances) from certain log tables. (Separately, the License Compliance facility includes built-in daily and end-of-period purging of Log- classes.)

These tables support miscellaneous capabilities.
