Here we add a new "rally info" command, which, based on the input,
prints descriptions for different entities in Rally (in this patch -
benchmark scenarios & scenario groups, more entities are to follow
(deployment engines etc.)). This command makes use of docstrings by
parsing them and printing them in CLI in human-readable form.
The command should be called as "rally info find <query>" (or, in case
of an explicit parameter setting, "rally info find --query=<query>").
Samples:
$ rally info find create_meter_and_get_stats
CeilometerStats.create_meter_and_get_stats (benchmark scenario).
Test creating a meter and fetching its statistics.
Meter is first created and then statistics is fetched for the same
using GET /v2/meters/(meter_name)/statistics.
Parameters:
- name_length: length of generated (random) part of meter name
- kwargs: contains optional arguments to create a meter
$ rally info find Authenticate
Authenticate (benchmark scenario group).
This class should contain authentication mechanism.
For different types of clients like Keystone.
