We are able to see what castor is receiving in the NEXRAD2 feed using
the LDM utility 'notifyme':

<as ldm on a machine in the unidata.ucar.edu domain>
 notifyme -vl- -f NEXRAD2 -h castor.rcac.purdue.edu
Apr 09 17:44:24 notifyme[14910] NOTE: Starting Up: castor.rcac.purdue.edu: 
20140409174424.518 TS_ENDT {{NEXRAD2,  ".*"}}
Apr 09 17:44:24 notifyme[14910] NOTE: LDM-5 desired product-class: 
20140409174424.518 TS_ENDT {{NEXRAD2,  ".*"}}
Apr 09 17:44:24 notifyme[14910] INFO: Resolving castor.rcac.purdue.edu to 
128.211.158.124 took 0.040026 seconds
Apr 09 17:44:24 notifyme[14910] NOTE: NOTIFYME(castor.rcac.purdue.edu): OK
Apr 09 17:44:25 notifyme[14910] INFO:    18730 20140409174424.645 NEXRAD2 
547037  L2-BZIP2/KAMX/20140409174251/547/37/I/V06/0
 ...

This tells us that castor is correctly getting the NEXRAD2 data and its
ALLOW for machines in the unidata.ucar.edu domain is working correctly.

But, a comparison of the NEXRAD2 volumes being reported by castor
with those being reported by the IDD top level relay that we operate,
idd.unidata.ucar.edu) show that the real time stats volumes that castor
is reporting are measurably less:

uni16.unidata.ucar.edu (one of the real-server backends of 
idd.unidata.ucar.edu):
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?NEXRAD2+uni16.unidata.ucar.edu

castor.rcac.purdue.edu
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?NEXRAD2+castor.rcac.purdue.edu

This unexpected difference is a flag to look harder at the setup on castor.

Questions/request(s):

- are there any abnormal looking messages in the LDM log file on castor?

- can you send the output of 'ldmadmin config' on castor?

Cheers,

Tom
