perfSONAR User Q&A and Other Discussion

[Peter Jacobs <>]

I have a similar experience, except that my page goes from loading to this error

Error retrieving test data: Gateway Time-out after about one minute.  I upgraded to 3.4.1 and the error went away for a few days, but now it is back.

 

The change I made that created the timeout was to add a sixth scheduled test.  That test is to a node that seems to be on a slow segments with packet loss (based on reports when it has decided to work).  I assumed that when one selected Throughput/Latency graphs that the node simply reads its own database, but I have to wonder if the node is also gathering data from the remote nodes in the configured tests.  If the latter is true then I would ask that the screen populate what it can - when it can - as it is received.  Right now it is all or nothing with that display page even though I know the data is some there.

 

Likely a discussion for January.

Subject: [perfsonar-user] ’Throughput/Latency Graphs’ page is stuck at ‘Loading’

 

Hi all,

 

Quick question, my ’Throughput/Latency Graphs’ page is stuck at ‘Loading’. Is there any method for debugging?

 

What all I did recently is changing the IP from A to B and then to A. Maybe this is the root of problems? 

 

By the way, reboot doesn’t work. 

 

Here is my URL: http://115.25.138.244/serviceTest/psGraph.cgi

 

Thanks,

Jarvis
