The primary goal is to be able to run all Tempest tests
and verify OpenStack when profiling is enabled. Also this patch
allows to:
* manually verify that certain services are properly instrumented
and produce trace events when a scenario is executed;
* write automatic tests for trace coverage;
* profile certain tests from performance perspective.
A new parameter is introduced into tempest.conf:
* profiler.key - the key used to enable OSProfiler (should
match the one configured in OpenStack services)
To test the patch on DevStack:
1. Enable osprofiler with Redis collector in local.conf:
enable_plugin osprofiler https://git.openstack.org/openstack/osprofiler master
OSPROFILER_COLLECTOR=redis
2. Run all Tempest tests or select some, e.g.:
tempest run --regex tempest.api.network.test_networks.NetworksTest.test_list_networks*
