perfSONAR User Q&A and Other Discussion

[<>]

Hello all,

I installed the testpoint bundle on one of our system and I was able to
schedule nuttcp, iperf2 tests but iperf3. Below is the error message and
troubleshoot message. In addition, I was able to run the standalone iperf3
tool between the 2 systems. Please let me know if you have any advices. I read
a previous post said the system might be overwhelmed but in my case the other
2  throughput tools are working functional.

$pscheduler task --assist xxx:9443 throughput --dest yyy --dest-node yyy:9443
--source xxx --source-node xxx:9443
Submitting with assistance from xxx:9443...
Unable to post task: Unable to determine participants: Process took too long
to run.
The 'pscheduler troubleshoot' command may be of use in problem
diagnosis. 'pscheduler troubleshoot --help' for more information.

$pscheduler troubleshoot --host=xxx:9443
Performing basic troubleshooting of xxx:9443.

xxx:9443:

  Checking path MTU... Not supported
  Checking for pScheduler... OK.
  Checking clock... Unsynchronized (Not considered fatal)
  Idle test.... 14 seconds.... Checking archiving... OK.

pScheduler appears to be functioning normally.
