In the GrabPERF system, all of the detail charts are built off of the raw data table. Now, for some insane reason, I was storing 50 days of raw data. The furthest back that any of the configured raw data graphs goes is 7 days.
I reset the data purge script to drop data older than 10 days. This should speed up queries and graph displays.
If certain users would like to keep data for longer, I could modify the drop procedure for custom data storage lengths. Just let me know if you require raw data from longer periods and I will begin development on this.
