It is our experience that in Celerra Monitor we can save statistics for up to 12 weeks. This has to be set individually for each resource that we want to monitor.
Three questions.
1) Why only 12 weeks of data?
2) Why do we lose these statistics when we reboot the control station?
3) How can we save statistical data on the nas control station so it survives a reboot?
Sorry I didn't reply sooner. I've been out of the office. Perhaps celerra monitor data is stored for 12 weeks and I just misunderstood. I'm pretty certain that I've been told that cpu & memory utilization stats for server_2 in celerra manager are lost when the NAS control station is rebooted ... and felt confident that this is what we've experienced. We've only just recently gone back to Celerra Monitor as a resource monitoring tool. So ... assuming that 12 weeks worth of data is what we get at most ... unless we change some control station file size ... how do we change that file size? Where is that file? Thanks!

I wouldnt be surprised if the CPU and memory stats in Celerra Manager were pulled realtime and not stored - but I'm quite sure the same stats in Celerra Monitor dont get reset after a data mover reboot.

I dont think you can change that - Its dependent on the NAS control LUN sizes which depend on the version of DART
what you can do is to change the time interval - if you poll less often you can store longer periods
