Re: VMSTAT output on HPUX

Oh... and keep in mind, just the Total/Free for physical memory is typically not all that interesting on HP-UX. The kernel caches for performance aggressively on many levels (kernel dynamic memory, file caches, buffer caches, etc.). These caches typically stick around until free memory drops to around 1% or so [i.e. when there's memory pressure -- though that can have different meanings when products like PRM come into play and sub-system level accounting is used].

To find _where_ all the memory is being used takes a lot more diving through pstat if you want to do it yourself... or using Glance (which did it for you) or unsupported tools meant only for support which leak out from time to time. If free memory is enough, that's great -- but you might want to take a step back and let us know what you're really trying to do to see if that's meaningful.
