cli-benchmark::default

Add the cli-benchmark default recipe to your Chef configuration:

config.vm.provision "chef_client", id: "chef_client" do |chef|
  chef.add_recipe "cli-benchmark" # @x.x.x version is optional
  chef.json =
  {
    'cli-benchmark' => {
        'packages' => %w(vim sysbench),
        # Strive for idempotency here (i.e., multiple executions shouldn't crash)
        'install' => [
          'mkdir -p /usr/local/sysbench',
          'cd /usr/local/sysbench',
          '[ -e file.tar.gz ] && wget http://example.com/folder/file.tar.gz',
          'tar -xzf file.tar.gz',
        ],
        'pre_run' => 'echo "This will be run immediately BEFORE the benchmark starts" > log.txt',
        'run' => 'sysbench --test=cpu --cpu-max-prime=20000 run',
        # Repetitions include pre_run and post_run
        'repetitions' => 3,
        'post_run' => 'echo "This will be run immediately AFTER the benchmark ends" > log.txt',
        'metrics' => {
          # [name of the metric] => [regex to extract result from stdout]
          'execution_time' => 'total time:\s*(\d+\.\d+)s',
        }
    }
  }
