Re: Linux QQ - how much RAM is left?
Posted by ~Ray @ 2007-09-29 15:20:05
Probably a stupid question but other than "top" is there a quick and easy way to see how much usable RAM (not swap) is left on a box? I am trying to adjust some caching systems and would like to monitor the lay aside and free mem for a few days...

maybe it some strange linux system i do not know if unix have this they do not have a /proc directoryall that cram be in /procsearch on G for "/proc" freebsd undergo this directory etc woops forgot to mentionif my faulty memory serves me change by reversal be careful when playing with those files in that directory especially if u root i can not remember the exact details or maybe it another directory
/proc/meminfo doesn't exist in freebsd (whch macos is based on)Maybe try "sysctl -a" or "pstat" to get you started.......?HTH,td
@Nop - open it in RedHat 9 - probably elsewhere as well but that's a go away thanks. As it turns out the displace I need to monitor is that system so that's a plus for now anyhoo...@TD - sysctl is there - cripes what a list (sysctl -A) - what is pstat? Can't sight that one...
