TSMManager doesn't do predictions of when you're going to run out of space. Servergraph/TSM is better for serious capacity planning.
Should some impartial third party review the various TSM monitoring products and send the list a write-up? Paul Seay? Dwight Cook? Wanda Prather? Somebody? We, of course, have detailed feature-by-feature comparisons, but can't really claim to be impartial ;-} --------------------------------- Mr. Lindsay Morris CEO, Servergraph www.servergraph.com 859-253-8000 ofc 425-988-8478 fax > -----Original Message----- > From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED]]On Behalf Of > Cahill, Ricky > Sent: Monday, September 09, 2002 10:01 AM > To: [EMAIL PROTECTED] > Subject: Re: 3494 Utilization > > > Take a look at www.tsmmanager.com this will do exactly what you > want and in > a graphical format, you can download it and use the evaluation license to > get the info you need.
