Configuring Historical Reporting
Configuring the Database Capacity Threshold for a Purge
Use the purge purge-capacity command in historical reporting database configuration mode to set the 
purge threshold as a percentage of the total database capacity and the number of days of historical data 
that is to be purged from the database.
When the database capacity reaches the configured threshold, historical data older than the configured 
days-to-purge value is removed from the database. The default purge capacity percentage is 90, and the 
days-to-purge default value is 7. The maximum purge capacity percentage value allowed is 90. The no 
and default form of this command sets the purge capacity percentage value to 90, and the number of 
days-to-purge to 7.
