Quoting Martin Knoblauch <[EMAIL PROTECTED]>:

Hi Ashutosh,
 sorry for the wrong port. I meant of course 8651.

 You could try to run "gmetad" with a high debug level. This could help
to track down the problem.

[EMAIL PROTECTED] ~]# /usr/sbin/gmetad -d10
Going to run as user nobody
Sources are ...
Source: [Blaze, step 15] has 1 sources
        192.168.1.1
xml listening on port 8651
interactive xml listening on port 8652
cleanup thread has been started

it shows absolutely nothing after that. from another terminal, if i do  
telnet localhost 8651, it also stays hung.

heres gmetad.conf after pruning comments:
data_source "Blaze"   15 192.168.1.1
xml_port 8651
interactive_port 8652
rrd_rootdir "/scratch/rrdtool-1.2.15/lib/rrds"

heres a pruned output of telnet localhost 8649:

This is surprising since it does not show any expected metrics besides  
the name and owner.
