Discuss Configuring and Managing logs
One should not confuse Alert logs with application logs. Whenever there is an anomaly detected during the runtime of an application, Pega Platform raises an alert by logging an event of the ‘ALERT’ level. The event data for the alert is logged in the PegaRULES-Alert-YYYY-MMM-DD.log file, not PegaRULES.log. For more information about Alerts, see the Alerts concept Community article.
