Dear Anne, Dustin and all,
Did you see this? We are still experiencing high latencies of 800-1000 seconds
on our CONDUIT feeds during the times when the GFS comes through that appear to
be coming from the host
vm-lnx-conduit2.ncep.noaa.gov
Here are the most recent lags. Any ideas?
Thanks,
Pete

Subject: High CONDUIT latencies from vm-lnx-conduit2.ncep.noaa.gov
Dear Anne, Dustin and all,
Recently we have noticed fairly high latencies on the CONDUIT ldm data feed
originating from the machine vm-lnx-conduit2.ncep.noaa.gov. The feed
originating from vm-lnx-conduit1.ncep.noaa.gov does not have the high
latencies. Unidata and other top level feeds are seeing similar high latencies
from vm-lnx-conduit2.ncep.noaa.gov.
Here are some graphs showing the latencies that I'm seeing:
>From

> - latencies for CONDUIT data arriving at our UW-Madison AOS ingest machine

>From
>https://rtstats.unidata.ucar.edu/cgi-bin/rtstats/siteindex?conduit.unidata.ucar.edu
> (latencies at Unidata)
[cid:50b9a476-503f-4e75-b22b-4bc99eff3cdc]
At least here at UW-Madison, these latencies are causing us to lose some data
during the large GFS/GEFS periods.
Any idea what might be causing this?
Pete
