perfSONAR User Q&A and Other Discussion

[Ian Gandon <>]

Hi,

 

Recently upgraded my perfsonar devices to 4.2.0 and seem to have run into an issue. I utilise a CentOS 7 backend and upgraded via yum.

 

I use the agent to deploy a template on my device which uses my measurement archive as a destination for the tests. Post the upgrade my throughput tests are failing.

 

On the test device itself (client side) it generates the following in the pscheduler log:

 

Run returned {"diags": "/usr/bin/iperf3 -p 5201 -c MA -t 10 --json", "succeeded": false, "error": "iperf3 returned an error: error - the server has terminated"}

 

And on the destination device (server side) it generates the following in the pscheduler log:

 

tool-iperf3/run ERROR    Exception not enough arguments for format string.

 

To me it seems like the server side of iperf3 is not starting due to an error and this is causing the client side to fail and complain. Running iperf3 manually (-s on the server and -c on the client sides) works normally.

 

I did notice Issue #911 has the same server side error but not sure if its related.

 

Hoping someone could give me some pointers on where to go from here?

 

Thanks for any help,

 

Ian
