Hello,
Though I've been running an LDM server for a few months both in downstream
and upstream capacities, I'm still struggling with a lot of this. We're
looking into the prospect of upgrading our server (right now it's just an
old linux box sitting in my office) and even taking over some of the campus
load, and I'm trying to understand the throughputs by looking at the
iddstats pages, but I still don't have a definitive explanation of the
"labels" on the graphs. A classic example is
<
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?CONDUIT+augustine.net.images.alaska.edu
>
Could I trouble somebody to take my line by line through the 8 lines in the
legend and explain the syntax to me (or point me to a document that explains
this)? "If" I understand the syntax correctly, it implies that this server
is receiving four "streams" (?) from ldm.aoos.org (and, I know for a fact
that he is), and four identical (?) streams from bigbird.tamu.edu?
Is this graph showing me "only" incoming packets (I believe someone told me
this is the case). To get a feel for outgoing packets, would I simply find
the iddstats pages of the downstream server and deduce it from the
downstream servers "incoming" packets?
For my own server, I'm looking at some EXP packets that I produce myself,
which then get picked up by NWS, but I also receive some EXP packets (COSMIC
stuff) from unidata:
<
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?EXP+bear.arsc.alaska.edu
>
When I look at iddstats for EXP, I'm not sure what I'm looking at - the
"label" on the graph doesn't suggest any unidata data source, so I'm
wondering if I'm looking at the outgoing packets that I generate?
I know these are stupid/basic questions, but I've been unable to find
something that would explain this to me, and any help would be appreciated.
Thanks a lot,
Don Morton
