We are (and have been for some time) seeing a huge latency (between 30 to 90
minutes) on the NEXRAD2 feed. At present, our constellation of three servers
are pulling from Texas A&M (bigbird & idd) and Michigan Weather Systems.
Are there network issues or something I might be missing?
Additionally, I'm noticing that the data we do receive is often incomplete.
For example, the most recent scan I received for KFWS (who has been in 212 for
the last few hours) included only 7 of the 14 tilts for reflectivity, and some
of the volume scans (like VIL) were absent entirely.
It's entirely possible that I need to tweak my pqact.conf settings, but it
seems like we didn't start having issues until the latency kicked up in the
last week or two. Here is what we have now (an excerpt from pqact.conf...feel
free to correct me if we've got this wrong):
# L2 data
NEXRAD2 ^L2-BZIP2/(....)/([0-9]{8})([0-9]{4})[0-9]{2}/([0-9]{1,4}).*/[SI]
FILE data/nexrad2/\1/\1_\2-\3.part
NEXRAD2 ^L2-BZIP2/(....)/([0-9]{8})([0-9]{4})[0-9]{2}/([0-9]{1,4}).*/E
FILE -close data/nexrad2/\1/\1_\2-\3.part
NEXRAD2 ^L2-BZIP2/(....)/([0-9]{8})([0-9]{4})[0-9]{2}/([0-9]{1,4}).*/E
EXEC safemv data/nexrad2/\1/\1_\2-\3.part data/nexrad2/\1/\1_\2-\3
If anyone else would be willing to provide an "ALLOW" entry for one or two of
our servers for NEXRAD2, we would be very appreciative. (We're bringing on
several new servers over the next two or three months…with at least one being
1Gbps…and we will be happy to share the bandwidth and spread the love.)
