CPU utilisation

[Praveen Bezawada]

Hi
Are there any commands which give output of CPU utilisation that can be used as input for other commands.
I tried top but it could not be piped.
Please help...
Thanks in advance.

Hi ,

You can use sar -u .

Also vmstat gives you CPU utilization.

Praveen,
If you have measureware installed on your systems you
can make use of the "extract" command.
Pls try. It gives you very good reports of resource utilization. That eliminates the need to pipe any output
to any other command. You can, then, generate nice and informative reports, that help you in capacity planning.

Rgds,...

sar -u 5 5 is the best and is the most accurate tool to measure this. top is not always as accurate as sar.

sar -uM 5 5 if multiple processors.

You can use sar to direct the output to a file . In addition use uptime to check the cpu load averages.

Hi,

If you would like to plot cpu load averages graphically on the web, you can feed a MRTG grapher with the OID value of 1.3.6.1.4.1.11.2.3.1.1.3.0 via snmpget over the network.

Be sure however to check that the snmp daemon is running on that system.

Hope this helps. Regards.

You can use top to get what you need...

$topout=`export TERM=ansi; /usr/bin/top -d 1 |/usr/bin/grep avg`;

I use this to get the line with avg cpu time on it and then run it through perl to get the avg times...
