Is there any portable way to retrive the system statistics like load
average, free memory, swap, disk io in bolcks, packets read and
written by eth etc in unix operating systems (system calls
preferrable). I found some user commands like vmstat, netstat and top.
Please let me know abt other alternatives.

Thanks in advance

There is no portable way to access the information that
you want. This is why our company is in business.

Pirabhu,
You might find the OpenSysMon open source software package useful.

It comes with scripts to do what you want for lots of different UNIX
platforms and is very easily extended. See http://www.opensysmon.com

http://ftp.opensysmon.com is a shell script archive site with an
opensource system monitoring software package designed for scripts
and fully compatible with cron.

Is there any portable way for measuring system statistics like load
average, disk utilisation, network utilisation, memory and swap free etc
in unix systems(system calls preferrable). I found some user commands
like vmstat, uptime and netstat for the same purposes. Please let me
know if there are any effecient alternatives (again system calls
preferrable).

Thanks in advance

Not really, and it's mostly because these concepts are not portable. As
a trivial example, what does free memory mean? Physical memory not in
use? And is swap free if it's reserved in case shared pages are
modified?
