Regarding sar command

Dear all,

How can I use sar command showing the info. for different system resources including the utilization of CPU, memory, disk, system kernel parameter (e.g. nfile, maxfile, etc.), network, no. of users, and other important figure? Thanks!

Best Regards
Ajk

Well, you could check the man page, but the basics are:

sar -u : CPU Utilization
sar -d : Disk Activity
sar -b : Buffer Activity
sar -w : Swapping Activity (but sar is not very good at memory related info)
sar -q : Queue lengths (vmstat is better at this)
sar -c : System calls

sar does not report kernel parameters per se, nor no of users (use who | sort -u |wc -l), network info is better handled by lanadmin/netstat.

Does this help?

Pete
