Why don't you simply run "top" on your board, then?

I tried to run "top" on my custom board, but no success. No message
appears on console. Do I need to do anything special, any configuration?

You did mount the /proc filesystem, didn't you?

Or read /proc/stat?

I will try this. What kind of information can get from /proc/stat? Is it
any kind of statistics?

Yes, kernel statistics:
user, nice, system, jiffies * #_cpus - (user + nice + system)

See fs/proc/kstat_read_proc/proc_misc.c
