I'm on Redhat and Suse systems. Seems like the old HP systems didn't use swap until things got bad.

Memory and Swap are usually about 100% used regardless of system load according to 10g Grid Control & the OS (top & swapinfo)

How can I tell actual memory or swap usage?

How about pages in/out over a time period?

Is there a utility for this?

Then there's the system load. If we're at 37 average load, we're really at 100% capacity .. aka dead, unable to accept connections. Maybe I should apply a multiplier to this load number to get actual.

Any ideas on realistically managing memory on Linux?
