Hi, all...

I am trying to monitor a server, and I don't know what should be a normal cpu load on a server.
Is there a manual or a webpage I could read about this?
I am using the command "vmstat" to see the user and system load in the system.

Thanks...

My server has a load average of 0.2 on a AMD Athlon 64 X2 5600+ cpu.

I have around 30 webpages hosted there, teamspeak2 server, world of warcraft server and a DOD server running.

basically on a single core everything below 1 is good, on a dualcore anything below 2 is good, on a quad core anything below 4 is good as server load.

I am confused....

top - 07:35:05 up 7:22, 2 users, load average: 0.58, 0.72, 0.71
Tasks: 195 total, 2 running, 193 sleeping, 0 stopped, 0 zombie
Cpu(s): 12.4%us, 3.9%sy, 0.2%ni, 81.3%id, 1.6%wa, 0.3%hi, 0.3%si, 0.0%st

In this output of top, I see a load average...but in the command vmstat...

procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----
r b swpd free buff cache si so bi bo in cs us sy id wa
0 0 0 63028 226768 1037076 0 0 13 24 139 436 14 6 80 1

I see the US(user) and SY(system) and the ID(idle) time of the cpu. Does this reserves to the actual percentage time that the user and system use the cpu?
and also..what does this load average in the top commands refers to?

the load average in top/htop is over a given time... the first one the last 10 secs, second one the last minute and third one the last 10 min - if I'm not mistaken.

No clue what vmstat shows. don't really even know what that is.
