You're right. Raw data files are huge. One option is to make the interval larger, but this also very much limits the detail you can see in your real time data. If you don't care about I/O performance, you could disable that domain and save some more. You probably have already disabled seeks and scheduler data. An alternative product I know of uses a condensed format for performance data to save disk space, disk I/O and processing time. Just checked: and on a pretty serious system we need < 10 cyls per hour. This includes Linux process data of a few systems, and a lot of devices. The data is still with 1 minute granularity to do analysis and reporting. Rob -- Rob van der Heij Velocity Software, Inc http://velocitysoftware.com/
