Adaptive Server accumulates CPU and I/O statistics until you clear the totals from syslogins by running sp_clearstats. sp_clearstats initiates a new accounting interval for Adaptive Server users and executes sp_reportstats to print out statistics for the previous period.
Choose the length of your accounting interval by deciding how you want to use the statistics at your site. For example, to do monthly cross-department charging for the percentage of Adaptive Server CPU and I/O usage, the System Administrator would run sp_clearstats once a month.
