I'm sorry to report that you should be getting metric data back on
Tru64. Sadly, I can't offer any developmental support here now because
all our Alpha are belong to dumpster (although for the record, I am the
one to blame for the monitoring core running on Tru64 to begin with...
sorry about that!).
The metrics aren't being reported by the monitoring core. Either
something went wrong with the build (just because it compiled doesn't
mean it really works ... ) or something is wrong at runtime. To check
runtime, run the monitoring core in debug mode and see what kind of data
you get out of it.
I'm not familiar with the Tru64 code, but a number of metric
implementations require that you be root to run them. This means they
fail in intresting ways with the default behavior of running as nobody.
It might be worth a try to use the config file to cause gmond to run as
root all the time and see if that fixes the problem.

Running gmond as root (ie. no_setuid on) does not seem to make a
difference (although, if it did I don't think that would be such a
great idea).
I did have a small problem compiling machine.c -> machines/osf.c.
There was a line break in a string on line 163(i believe). Here is
a trivial patch:

I will try to rebuild and pay closer attention for other problems.
