perfSONAR User Q&A and Other Discussion

[Antoine Delvaux <>]

Hello Jason,

No, it is not a requirement to have throughput tests running to have OWAMP 
results show (would rather be the opposite).

To debug your issue further, you should try to run latency/OWAMP measurements 
with pScheduler on the CLI (not only owping).  You can try something like:

pscheduler task latency --dest one.of.your.nodes

If this gives you some error message or doesn't return any result, you can 
probably learn more about your issue with

pscheduler troubleshoot
pscheduler troubleshoot --host one.of.your.nodes

You can also try some

pscheduler ping one.of.your.nodes

You can find more information about pScheduler at 
http://docs.perfsonar.net/pscheduler_intro.html

If this work, you'll need to check if esmond/cassandra is running and if 
there are no errors in /var/log/pscheduler or /var/log/esmond or 
/var/log/httpd/

Hope this helps,

Antoine.
