Based on the System settings, alerts and other KPI data is automatically not removed from the system as per the defined retention period.

Error Messages

Not Applicable

Steps to Reproduce

  1. Login to Autonomic Event Services (AES) Manager Portal.
  2. Navigate to Administration Section.
  3. Select the system name under current system drop down on top right.
  4. Click on Purge System Alerts.

Root Cause

A defect or configuration issue in the operating environment At some point in the past the PegaAES agent was not running properly. Alert data accumulated so that normal processing could not take place.

The number of alerts in the DATA.pegaam_alert table had millions of rows. Some as old as 6 months. The retention configured in the AES settings was 14 days.


In the database tool of preference delete rows month by month from DATA.pegaam_alert until there are only alerts left with pxCreateDatetime less than 14 days ago.
If exceptions are also not properly groomed then repeat that process with DATA.pegaam_exception.
