Hi Mark, just to be sure I got correctly your network setup - you want to stress test full OpenStack installation by simulation of NIC and storage utilization, am I right?
In that case vsperf can be used in "trafficgen mode", where it only controls selected traffic generator and collects final results. As of now, vsperf doesn't collect any periodic metrics from the traffic generator. It runs selected traffic pattern (e.g. RFC2544 Throughput) and records measured values. However I think that both scenarios would be possible, but first scenario would have to be slightly changed: 1) I start up VSPERF on the NICs that represent the tenant network in an OpenStack installation. MK=> and measure e.g. throughput of setup without the storage network stressing 2) After 10 minutes, start up StorPerf read/write test that should stress the OpenStack storage network 3) See if there is a change to the VSPERF throughput. MK=> i.e. execute vsperf again with the same settings as before and compare measured values Second scenario can be executed as proposed by you, without any changes.

The idea behind starting one first is so we can see the delta at the point where it started. We certainly can run both independently as a baseline, and then run them together can measure the delta that way...

I think it is time testing projects together develop some sophisticated stress test cases across components of the system. Just 1 question, why start VSPERF and STORPERF separately. Why not start both tests simultaneously and monitoring/reporting the throughput variation along time.

I'd like to get a quick overview of VSPERF and how the metrics are captured. Sorry if these are dumb questions :) First, is there a test that simply pushes packets over the network to see what the maximum throughput is, like a saturation test? Does VSPERF capture periodic metrics, or just a summary report at the end? If I change something in the network while the test is running (such as adding more traffic outside of VSPERF), is there a way to see the impact of that while the test is running? The reason behind the questions are for the following scenario: 1) I start up VSPERF on the NICs that represent the tenant network in an OpenStack installation. 2) After 10 minutes, start up StorPerf read/write test that should stress the OpenStack storage network 3) See if there is a change to the VSPERF throughput. Alternatively, as StorPerf does have minute by minute metrics, we can do this: 1) Start StorPerf read/write 2) After 10 minutes, start VSPERF to stress the tenant network NICs 3) Look at the change in StorPerf throughput at the time that VSPERF starts. Thoughts?
