Effectively, nsclient, NC_Net and nsclient++ can all do that (I
personally use NC_Net). The problem with them is that they cannot get
the average value for a real period of time. Also NC_Net doesn't handle
counters that go away momentarily (i.e. restarted service).

One of my project is to write a windows daemon that does that. When
queried for a counter, it registers it, poll regularly after the
specified interval and cache the value. The client can then connect at
any time to request the value. Unfortunately as long as the company I
work for doesn't want that (the idea is to get the data into RRD files)
the chances I even start this project are very slim.

Also the only programming language I know enough for that is Perl, which
is not the ideal one for that platform (though it should be able to poll
remote machines in a domain, so one Perl-enabled server should be able
to monitor all servers). If anyone wants to write this in C or C# I'd be
glad to give the exact details of how the daemon and client should work
though.
