memory diagnostics/questions - how to?
I'm seeing my memory get used up and now have only 10% free having had 50% free when the box was rebooted.
What I would like to do is find some way to break down the memory usage on my centos 5 server in some detail.
Obviously vmstat, free and ps give me some clues but is there any tools available to provide a better view of whats going on? I've googled around for a few things but not yet spotted anything straight forward.
One more thing on the subject, I noticed yum-updatesd was using the most memory (9.4%) so I service yum-updatesd stop'd it. Is it your opinion that this is bad practice? I assume the daemon is constantly looking for security updates etc?
