The information we have on your setup is available online as follows:

Unidata HomePage:
http://www.unidata.ucar.edu

->Tools -> IDD
  http://www.unidata.ucar.edu/software/idd/

  ->Real-Time IDD statistics
    http://www.unidata.ucar.edu/software/idd/rtstats/

    ->Statistics by Host
      http://www.unidata.ucar.edu/cgi-bin/rtstats/siteindex

Search the last page for 'uncc', and you will see an entry for
what is presumably your machine:  meteo.uncc.edu.
Clicking on that link leads you to a page that shows what
datastreams you are ingesting (if this really is your machine),
and some statistics for those feeds:

http://www.unidata.ucar.edu/cgi-bin/rtstats/siteindex?meteo.uncc.edu

It appears that you are currently receiving the the following datastreams:
GEM, HDS, IDS|DDPLUS, NEXRAD2, NEXRAD3, NGRID, NIMAGE

To see if you are actually receiving data, you can click on the 'volume'
link for any feed in the list.  For instance, clicking on 'volume'
for IDS|DDPLUS show that you are, in fact, receiving the data in
this datastream.

To see who you are getting any datastream from, click on the 'topology'
link.  This shows that you are getting the IDS|DDPLUS data from
idd.unidata.ucar.edu.

Clicking on the 'Cumulative Volume Summary' link on the bottom of
the page that lists the datastreams that you are getting will show
some summary statistics about the data you are receiving:

Data Volume Summary for meteo.uncc.edu

Maximum hourly volume   2253.565 M bytes/hour
Average hourly volume   1310.264 M bytes/hour

Average products per hour      96569 prods/hour

Feed                           Average             Maximum     Products
                     (M byte/hour)            (M byte/hour)   number/hour
NGRID                   652.474    [ 49.797%]     1387.344    15652.800
HDS                     248.602    [ 18.973%]      447.708    18791.160
NEXRAD3                 194.767    [ 14.865%]      219.455    28534.800
NIMAGE                  154.497    [ 11.791%]      230.883      180.920
IDS|DDPLUS               35.365    [  2.699%]       43.296    31293.680
NEXRAD2                  21.731    [  1.658%]       30.766     1921.880
GEM                       2.828    [  0.216%]       29.473      193.880

So, you _are_ receiving over 1.3 GB/hour of data on average with peaks
over 2.2 GB/hour.

The fact that you don't think you are receiving data when you are tells
us that you are not processing the data you are receiving.

How can we help you get things going again?

Cheers,

Tom
