Hi Aaron,

Thanks for your reply, I think cassandra is working.

Hey Jarvis,

That’s an odd error. Is cassandra running?

Cheers,

Aaron

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):

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
