Data Purging is enabled by default for all the aggregation tables. However, you can purge data in certain alert tables, namely APIMIpAccessSummary and APIMIpAccessAlertCount tables, which have the potential to grow quickly like aggregation tables. Follow the instructions below to purge the data in the latter mentioned alert tables.

1. Configure WSO2 Open Banking API Manager (WSO2 OB API-M) with WSO2 API-M Analytics, and start WSO2 API-M Analytics, WSO2 OB API Manager, and the WSO2 API-M Analytics Dashboard node in the latter mentioned order. For more information, see Integrating API Manager Analytics.
2. Access the Business Rules via the WSO2 API-M Analytics dashboard.
   https://<HOSTNAME>:<DASHBOARD_PORT>/business-rules
   For example:  https://localhost:9643/business-rules
3. Click the edit link that corresponds to the APIM DATA PURGING business rule.
   
   

4. Click Save and Deploy to enable data purging in the APIMIpAccessSummary and APIMIpAccessAlertCount tables.
   When the above business rule is enabled, it will purge data from APIMIpAccessSummary and APIMIpAccessAlertCount tables every time the trigger is triggered. The default time interval for the trigger is 1 years.
   

   Info
   If you need to purge the data immediately or cannot wait for the next trigger, then you need to reduce the default time interval to trigger data purging by changing the Time Interval For Trigger value to a smaller value (e.g., one minute). You can set the time interval for the triggerin seconds, minutes, hours, days, months, and years.
