perfSONAR User Q&A and Other Discussion

[Casey Russell <>]

Group,

     Our installation of PerfSonar has been in place for a bit over a year.  I recently took over management of it, and I'll start off by pointing out that our overall installation is a bit non-standard, however, the PingER portion is typical.  

     I think this particular problem has been present since very early on, and perhaps from day one.  However it's also possible that it worked early on, but yum updating broke it many months ago.  

     Basically what's happening is the hosts (as near as I can tell from the logs) are collecting the PingER data appropriately, but when you try to pull up a graph, you get a page that simply says "no data".  The PingER log shows the following:

The request for a graph began at 09:59:25.

Does anyone have any insight into what's failing here, or why?
