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 ;-}
