Meeting summary --------------- * We now have a Docker image with our test tools on DockerHub as opnfv/cperf, so `docker run -it opnfv/cperf` works (dfarrell07, 18:17:48) * LINK: https://hub.docker.com/r/opnfv/cperf/ CPerf test tools Docker container on DockerHub (dfarrell07, 18:17:53) * jamoluhrsen points out that next TODO is to install NSTAT on this test container (dfarrell07, 18:18:31) * ACTION: dfarrell07 or Nikos to install NSTAT on test container (dfarrell07, 18:18:49) * dfarrell07 and Al talk about Pharos reservation system and changes to how pods are managed (dfarrell07, 18:22:20) * discussion about if POD 2 status (dfarrell07, 18:22:36) * we're unsure how much of POD 2 works (dfarrell07, 18:22:48) * dfarrell07 reports back on testing project progress at plugfest and docs given on this morning's OPNFV test call (dfarrell07, 18:24:50) * LINK: https://wiki.opnfv.org/display/functest/Testing Carbon Functest testing overview wiki, recently updated by plugfest and Morgan (dfarrell07, 18:24:58) * LINK: http://testresults.opnfv.org/testapi/test_projects/cperf API for CPerf's OPNFV tests (dfarrell07, 18:25:05) * LINK: http://testresults.opnfv.org/testapi/test_projects/promise API for CPerf's OPNFV tests (dfarrell07, 18:25:11) * Nikos has released an updated version of their perf paper https://raw.githubusercontent.com/wiki/intracom-telecom-sdn/nstat/files/ODL_performance_report_v1.2.pdf (dfarrell07, 18:30:54) * dfarrell07 asks Nikos for overview of interesting results (dfarrell07, 18:31:42) * Nikos asks for feedback about paper, which metrics and parts we cared about (dfarrell07, 18:31:55) * Nikos points us at ex summery for highlights (dfarrell07, 18:32:06) * Soon results are coming via dashboard, in more detail, live (dfarrell07, 18:32:22) * Jamo points out that we can run tests in ODL infra using opnfv/cperf image, maybe more quickly/easily (dfarrell07, 18:35:26) * Nikos saw OOM fails when running cbench test, but doesn't think it's ODL b/c JVM would limit RAM, not seeing same issues when using mini/multinet (dfarrell07, 18:37:00) * Note that Nikos has stability tests in this report, which we don't in ODL report, so point people to this (dfarrell07, 18:37:23) * Luis points out that it's good how they report RAM/CPU/etc info in report, we might start doing that in ODL whitepaper, Luis has intern who will work on similar (dfarrell07, 18:37:53) * ACTION: dfarrell07 will work on adding NSTAT install to opnfv/cperf image (dfarrell07, 18:38:20) * Nikos gives tip about using "flame graphs" in perf reporting and profiling (dfarrell07, 18:39:46) * LINK: http://www.brendangregg.com/flamegraphs.html Flame graph tool Nikos has turned us on to (dfarrell07, 18:40:47) * Luis is super excited about this Flame Graph thing ;) (dfarrell07, 18:43:41) * Luis talks about 1.1 of perf whitepaper, which should come out Monday (dfarrell07, 18:44:34) * There were some minor changes, but the general idea is the same - they perf about the same and work for the usecases being considered (dfarrell07, 18:45:01) * Much better wording in second report, time to edit/iterate more (dfarrell07, 18:45:13) * ONOS has reviewed paper, said yesterday they like it and are fine (dfarrell07, 18:45:35) * Cluster testing and Java API testing are likely still going to be blogged about, not a big deal, flame war avoided (dfarrell07, 18:46:20) * For future work, we've asked ONOS to join CPerf for collab, not testing them ourselves in our whitepapers (dfarrell07, 18:47:14) Meeting ended at 18:51:03 UTC.
