It is a good thing you didn't try before this, because the power to the entire first floor of our building was off for most of the day. >- Comment, so far I'm able to get all the data including CONDUIT and >CRAFT, so I'm psyched about that. This is very convincing evidence to our >network engineers who now believe me that we have a problem on campus. Excellent. >The current test is running from just inside the campus firewall, I can't >get nearly the bandwidth from the College of Science.B > >- Is there a way to get stats, should the stats be showing up on the >rtstats page, or will this not work with emo? You sould see stats from storm.sjsu.edu IF it is reporting them back to us. The reqporting requires that you have a rtstats line in storm's ldmd.conf file and that port 388 traffic back to us is not being blocked. In addition, if a 'uname -n' on storm does not return a fully qualified hostname, then you would have had to edit ~ldm/bin/ldmadmin and set the hostname in it: change: chop($hostname = `uname -n`); # $hostname = "your.hostname.here"; to: # chop($hostname = `uname -n`); $hostname = "storm.sjsu.edu"; If you find that you have to make this change, you will need to stop and restart your LDM for the change to take effect: ldmadmin stop ldmadmin start >- My feed went down from 04Z until 14Z today, was emo fine during this >period? I brought the LDM up on emo yesterday afternoon at 15:15 our time. A quick check of the stats for it show that it has been up ever since: http://my.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?IDS|DDPLUS+emo.unidata.ucar.edu >- I would also like to test the ability to feed someone off campus, is >there anyway I could feed everything to a machine at Unidata for awhile, >or should I broadcast this request to the community? I setup a machine here in the UPC to feed from you. As a stress test, I am feeding everything with requests split 11 ways: request IDS|DDPLUS|FSL2|UNIWISC ".*" storm.sjsu.edu request HRS ".*" storm.sjsu.edu request NIMAGE ".*" storm.sjsu.edu request FNEXRAD|NNEXRAD ".*" storm.sjsu.edu request CRAFT ".*" storm.sjsu.edu request NLDN ".*" storm.sjsu.edu request CONDUIT "[05]$" storm.sjsu.edu request CONDUIT "[16]$" storm.sjsu.edu request CONDUIT "[27]$" storm.sjsu.edu request CONDUIT "[38]$" storm.sjsu.edu request CONDUIT "[49]$" storm.sjsu.edu Data is flowing, and the machine, dhcp22.unidata.ucar.edu is reporting stats that are viewable through our realtime stats web pages: http://my.unidata.ucar.edu/content/software/idd/rtstats/siteindex.php?dhcp22.unidata.ucar.edu So, the data path is: UPC NOAAPORT ingesters -> emo -> storm -> dhcp22 We should be able to get a good handle for the feed back to dhcp22 later today. >Thanks for your help as usual, No worries.

I started the feed 00Z Saturday or 5PM Friday your time, and I was out from 12Z to 22Z, which is 5am to 3pm your time Saturday. Anyhow, I'm glad that's all it was and I apologize for starting my feed without informing you. The stats should be flowing now, I just had a typo in my rtstats line in my ldmd.conf. To be consistent, I used your exact same feed patterns and just changed storm.sjsu.edu to emo....: request IDS|DDPLUS|FSL2|UNIWISC ".*" emo.unidata.ucar.edu request HRS ".*" emo.unidata.ucar.edu request NIMAGE ".*" emo.unidata.ucar.edu request FNEXRAD|NNEXRAD ".*" emo.unidata.ucar.edu request CRAFT ".*" emo.unidata.ucar.edu request NLDN ".*" emo.unidata.ucar.edu request CONDUIT "[05]$" emo.unidata.ucar.edu request CONDUIT "[16]$" emo.unidata.ucar.edu request CONDUIT "[27]$" emo.unidata.ucar.edu request CONDUIT "[38]$" emo.unidata.ucar.edu request CONDUIT "[49]$" emo.unidata.ucar.edu So, this is great, thanks for pulling a feed from storm, we'll see how it does. As a stress test, I do plan on stopping and starting the LDM a few times to see how we'll it can catch up. This machine is not very special (1.4 Ghz, 1 GB RAM), but hopefully it will do for a test) Thanks!! -Mike
