You can check it here  http://blogs.technet.com/askperf/archive/2008/04/11/an-introduction-to-pool-tags.aspx . There tools already available that displays pooltags and how much memory allocated to it like "PoolMon" or OSR Pooltag (Same as PoolMon but with GUI). But these tools do not provide the things that I need thats why I'm looking on some other way to create a program that similar to these tools but do more than just displaying and saving it to an output file.
