Performance Statistics Do Not Cover Enough Time

Problem: I want to graph performance counters over a long period of time but the statistics chart displays only very recent data.

Solution: Ask your SAP Control Center administrator to change the repository purging options to keep statistical data available for as long as you need it. By default, statistics are purged frequently to conserve disk space.
