Dataplane Tests Error in container command #53

Closed cunningr closed 1 year ago

cunningr commented 1 year ago

It looks as though the commands used to start iPerf in the containers are failing?

And therefore we are not getting any network I/O results from ./run.sh -t "dp_netperf_internode" but just the generic pod start/stop stats.

---update---

I can get these tests to run by deploying manually in the same environment and just running the test commands in sequence.

If the dataplane tests do run, where would I expect to see the results? I can't find anything that look like what I would expect for dataplane throughput and latency.

I think it may just be this test that is not working for me ./run.sh -t dp_netperf_internode. I don't seem to get any results in the log files.
