Maybe the problem is from esmond?

I tried to get the data manually from the REST API of esmond by sending request to '/esmond/perfsonar/archive/?format=json’, but I got this:

{"error_message": "Sorry, this request could not be processed. Please try again later."}

This error can be traced from the log of esmond(/var/log/esmond/django.log):

    for k in obj.data.keys():

AttributeError: 'NoneType' object has no attribute 'data'

So, is this error from esmond or somewhere else?

I'm having the same issue with one of my pS toolkit servers.  It was working recently but no longer. I'm running version 3.4.1-1 of the toolkit on the server that's stuck but also on a server that works.

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
