What are folks using to do TSM trending? I need to answer questions like these: - How long will our current supply of scratch tapes last, assuming constant usage? - If I add <insert a number> TSM clients similar to an existing client, how will it affect my tape usage? - What's our peak drive usage (smoothed over some reasonable interval)? - If we move certain TSM clients to an offsite TSM server and library, how many drives will I need offsite? - Why did my tape usage go up on <insert a date>? I've played with TSMManager some. It seems to answer some of those questions (like the drive usage) easily, and I'm guessing that it could answer the other questions with a bit more effort. Is that right? I've found that TSM's own tools (the TSM web GUI and that ghastly thing that's replaced it in TSM 5.3) give a better view of the trees than the forest. They're OK for day-to-day tasks, but not for trending. I would just as soon write Perl scripts to distill the logs, but my management would rather have me do other things, particularly if there's a canned answer out there. We're willing to spend money to get reliable answers to these questions. Thanks, anker
