sar questions

[Mag0007]

I am in the process of setting up system performance monitoring.

I have sar set up like this:

0,5,10,15,20,25,30,35,40,45,50,55 * * * 0-6 /usr/lib/sa/sa1
0 23 * * 1-5 /usr/lib/sa/sa2 -s 1:00 -e 23:40 -i 300 -A


My questions ise:
How do I view the sa2's output?

Any recommendations on using sar?

# sar -f sa2

 

[mohmin]

sar -P <processor or ALL> will tell you cpu activity on 1 or more of the processors


Sar only shows the history of cpu and i/o waits.

Its doesnt show us the memory part.

Look in the crontab for user "adm". There are predefined entries in there that are commented out by default. You might want to use those.

Jim:
exactly, thats what I been using.

0,5,10,15,20,25,30,35,40,45,50,55 * * * 0-6 /usr/lib/sa/sa1
0 23 * * 1-5 /usr/lib/sa/sa2 -s 1:00 -e 23:40 -i 300 -A

I know what the first sa1 does...but what does sa2 do? I am not sure what that line really does.
