[Support #TQY-200819]: Huge lags from idd.unidata.ucar.edu for CONDUIT?

Hi Pete,

re:

> CONDUIT yesterday?

Good question.  The latencies being shown for CONDUIT data coming from 
emo.unidata.ucar.edu
to idd.unidata.ucar.edu went south:

http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?CONDUIT+idd.unidata.ucar.edu

The portion of CONDUIT data that is showing high latencies is, however, small:

http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?CONDUIT+idd.unidata.ucar.edu

My first guess is that the products with very high latencies are ones that are 
being
received a second time, after the initially received ones have been scoured out 
of
the queue on the receiving machine.

Please check the relative volumes of the data for the different feed paths:

http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?CONDUIT+idd.aos.wisc.edu

The majority (if not all) of the products with the high latencies should be
"second trip" products (i.e., already received, but scoured out of the queue).

We will investigate what is happening on emo...
