What's using all of my memory?
I had a small server with 512MB of physical memory.
It was eventually swapping several hundred MB, so I
had it upgraded to 1.5GB of physical memory. Now it
is using all of that and swapping a couple hundred KB.
Although, checking through my other systems, I see
that every one of them maxes out the physical RAM
and uses a tiny bit of swap. I guess that's normal?
That said, is there any way to see WHERE all of the
memory is going? Perhaps to see how much certain
applications or services might be using?
If the OS wants to "cache" a bunch of data into RAM,
that's fine, but I'm still curious how much actual RAM
is being used by the apps and services, so that I can
tell when they're getting close to max'ing out...
