Re: Online System Info
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 ├в 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 ├в tam
sar -b 5 100 for buffer cache
ipcs ├в mob (To determine shared memory segement allocation)

Re: Online System Info
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.
