Weekly updates

November 25, 2013

Hello stackers,

here is the second report on our activities in Rally development for the past week.

The main results that have been recently merged with master are as follows:

  • Changes in the benchmark engine: we have significantly restructured the format of the input benchmark config (https://review.openstack.org/#/c/56035/). The changes make it more transparent to the end-user as well as more flexible. This will enable us to implement new features in the benchmark engine like running tests periodically or for a given amount of time. We have also refactored the test code related to benchmark scenarios by replacing ugly-looking nested with-blocks for mocks with a more readable decorator syntax (https://review.openstack.org/#/c/57732/);
  • Further work on splitting the system logic between the two basic entities, namely the deployment and the benchmark task. While still having the legacy combined config that contains information both on the deployment and on the benchmarks, we have closely come to the point where we can completely split everything related to these two entites. To be more precise, during the lask week we have made:

Our plan for the current week comprises:

We encourage you to take a look at new patches in Rally pending for review and to help us making Rally better.

Hello stackers,

here is the first issue of our weekly update notes on Rally, Benchmark-as-a-Service project for OpenStack. Once a week we are going to post a few remarks on what we have done and what we plan to implement in Rally during the next week.

During the past week we have been focusing our efforts on two main aspects of Rally development:

  • Splitting the Rally workflow into 2 parts: the OpenStack deployment part and the benchmark tasks running part. Both have been previously treated by the system as a single process configured once by the end user. Separation of deployment from benchmark tasks, however, allows one to reuse existing deployments. The current results here are:

We have also recently received several e-mails notifying us of a possible issue in the soft/hard server reboot benchmark scenario. We would like to thank all of you who reported the problem. We will try to fix it as soon as possible.

The Rally roadmap for the next week goes as follows:

  • Continue the work on separating OpenStack deployments from benchmark tasks: introduce the necessary CLI commands, integrate the Deployment class with deploy engines, rewrite the orchestrator part to support the separated deployments and benchmarks;
  • Implement multihost OpenStack deployment engine using LXC;
  • Add two new capabilities to the benchmark runner:
  • Benchmark launching for a given period of time (not a strict amount of times);
  • Launching several benchmarks with configured intervals.
  • Improve the benchmark config format to make it both more flexible and more clear for the end user;
  • Implement generic cleanup for our benchmark scenarios;
  • Work on automated output data processing and drawing plots for benchmark results.

Several patches addressing the above tasks are already available on Gerrit code review. You are welcome to take a look at them.
