perfSONAR User Q&A and Other Discussion

[Casey Russell <>]

Group, 

     I updated my systems early on Monday to 3.5 and worked through a couple of early issues to get everything stable by Tuesday.  However yesterday morning I came in to find that my Maddash dashboard had gone yellow again overnight.  I suppose it may (or may not) have been related to updates released the evening of the 29th (I do have automatic updates enabled).

     In short, the latency grid, and the TCP bandwidth testing grids still work fine for most hosts.  On my internal hosts, I've lost (in the Maddash dashboard) all UDP bandwidth testing.  The dashboard shows yellow with the warning text:  " Unable to find any tests with data in the given time range where source is ps-bryant-bw.perfsonar.kanren.net and destination is ps-wsu-bw.perfsonar.kanren.net"

     I've verified that I can manually run these tests between the hosts.  I've also gone back and verified that the bugs I've seen reported on the list over the last couple of days don't seem to be the cause of my issue.  However, I'm stumped as to just what IS going on.  I don't know how to query esmond well enough to see if the UDP test data is there, but this feels to me like a situation where the data is still there, but Maddash has lost it's ability to find it.  In situations where a test was running, but stops, you can typically still click on that Maddash square and see the old data, even if there's a recent blank spot.  In this case, there is not even any historical data. 

     Anyone have any thoughts on where to point me next?  http://ps-dashboard.kanren.net/maddash-webui

Maddash log data:

Lots more log data where that came from, but I won't pollute the list with it.  Ask if there's something you need to see to help and I'll provide.

Thank you in advance
