Hi,

The system is HP-UX 11.
How can see the online usage of CPU and Memory?

Can anybody help me, please?
Thanks,

Re: Online System Info

To find out processor speed,run:

example:
echo itick_per_usec/D | adb -k /stand/vmunix /dev/mem
itick_per_usec:
itick_per_usec: 360

This will be the speed in MHz.

To find out how many processors are in use, run:

example:
echo runningprocs/D | adb -k /stand/vmunix /dev/mem
runningprocs:
runningprocs: 2

This can also be done by using sar -Mu


To find out cpu load on a multi-processor system, run:

example:

sar â Mu 5 100 this will produce 100 data points 5 seconds apart.

sar -q 5 100 (for cpu run que)

To determine virtual memory configuration run the following command:
swapinfo â tam
sar -b 5 100 for buffer cache
ipcs â mob (To determine shared memory segement allocation)

Re: Online System Info

You can also configure something like cacti to collect the info. It totally depends on what's installed and licensed what you can do.

Something that's always installed and available is the 'top' command.

Glance is part of the measureware tools, which has a seperate license. And only works when you have root access, while top runs as a normal user.

Every problem has at least one solution. Only some solutions are harder to find.

top displays the top processes on the system and periodically updates the information. To know more about top:
