Description OpenShift BugZilla Robot 2021-07-07 13:21:53 UTC 
+++ This bug was initially created as a clone of Bug #1979554 +++

Description of problem:
Latency tests runs on V1.9 oslat version , while 4.8 cnf-tests image uses the latest version with modified tool options , and one of the used options in our tests is deleted so oslat tests fails to run because the no longer supported option --runtime. 

Version-Release number of selected component (if applicable):
4.8

How reproducible:
always

Steps to Reproduce:
1.pull cnf-tests image http://registry-proxy.engineering.redhat.com/rh-osbs/openshift4-cnf-tests:v4.8.0-51 
podman run -d -ti --privileged --entrypoint=/bin/bash registry-proxy.engineering.redhat.com/rh-osbs/openshift4-cnf-tests:v4.8.0-51
2. run only latency tests :
podman run  -v $KUBECONFIG:/root/kubeconfig:Z -e KUBECONFIG=/root/kubeconfig -e IMAGE_REGISTRY=registry-proxy.engineering.redhat.com/rh-osbs -e CNF_TESTS_IMAGE=openshift4-cnf-tests:v4.8.0-51 -e PERF_TEST_PROFILE=performance -e ROLE_WORKER_CNF=worker-cnf -e LATENCY_TEST_RUN=true -e LATENCY_TEST_RUNTIME=10 -e OSLAT_MAXIMUM_LATENCY=20 -e DISCOVERY_MODE=true registry-proxy.engineering.redhat.com/rh-osbs/openshift4-cnf-tests:v4.8.0-51 usr/bin/test-run.sh -ginkgo.focus="\[performance\]\ Latency\ Test"
3.

Actual results:
=================================================
-The test fails with the following error :
 Unexpected error:
        <*errors.errorString | 0xc0003dcc50>: {
            s: "timed out waiting for the condition",
        }

oslat V 1.10
Usage:
oslat <options>

This is an OS latency detector by running busy loops on specified cores.
Please run this tool using root.

Available options:

-b, --bucket-size      Specify the number of the buckets (4-1024)
-B, --bias             Add a bias to all the buckets using the estimated mininum
-c, --cpu-list         Specify CPUs to run on, e.g. '1,3,5,7-15'
-C, --cpu-main-thread  Specify which CPU the main thread runs on.  Default is cpu0.
-D, --duration         Specify test duration, e.g., 60, 20m, 2H
                       (m/M: minutes, h/H: hours, d/D: days)
-f, --rtprio           Using SCHED_FIFO priority (1-99)
-m, --workload-mem     Size of the memory to use for the workload (e.g., 4K, 1M).
                       Total memory usage will be this value multiplies 2*N,
                       because there will be src/dst buffers for each thread, and
                       N is the number of processors for testing.
-s, --single-preheat   Use a single thread when measuring latency at preheat stage
                       NOTE: please make sure the CPU frequency on all testing cores
                       are locked before using this parmater.  If you don't know how
                       to lock the freq then please don't use this parameter.
-T, --trace-threshold  Stop the test when threshold triggered (in us),
                       print a marker in ftrace and stop ftrace too.
-v, --version          Display the version of the software.
-w, --workload         Specify a kind of workload, default is no workload
                       (options: no, memmove)
-z, --zero-omit        Don't display buckets in the output histogram if all zeros.

1. run latency tests on the image that supports the fix of the bug :registry-proxy.engineering.redhat.com/rh-osbs/openshift4-cnf-tests:v4.8.0-58 
podman run  -v $KUBECONFIG:/root/kubeconfig:Z -e KUBECONFIG=/root/kubeconfig -e IMAGE_REGISTRY=registry-proxy.engineering.redhat.com/rh-osbs -e CNF_TESTS_IMAGE=openshift4-cnf-tests:v4.8.0-58 -e PERF_TEST_PROFILE=performance -e ROLE_WORKER_CNF=worker-cnf -e LATENCY_TEST_RUN=true -e LATENCY_TEST_RUNTIME=30 -e OSLAT_MAXIMUM_LATENCY=20 -e DISCOVERY_MODE=true registry-proxy.engineering.redhat.com/rh-osbs/openshift4-cnf-tests:v4.8.0-58  usr/bin/test-run.sh -ginkgo.focus="\[performance\]\ Latency\ Test"

 As one can notice from the above outputs , the test's pod started running properly on the updated image & it executed oslat using --duration flag instead of the deprecated --runtime that was in older version of oslat, and the latency test passed.
