Run It!

The easiest way to learn how Rally works is to use already existing OpenStack deployed by DevStack. So let assume that we have 2 VMs:

 Vm1 - 192.168.1.2 (with Rally)
 Vm2 - 192.168.1.3 (with OpenStack deployed by DevStack)

Preparing

1) Installing Rally & Zipkin on Vm1 To install Rally and Zipkin on Vm1 use this instruction

2) Installing OpenStack using DevStack on Vm2

 ssh root@192.168.1.3
 git clone https://github.com/openstack-dev/devstack.git
 cd devstack && ./stack.sh

Action!

Prepare you config file

Now we should properly configure task configuration:

base_task.json:

{
  "deploy": {
    "name": "FakeEngine", 
    "cloud_config": {
      "identity": {
        "url": "http://192.168.1.3/",
        "uri": "http://192.168.1.3:5000/v2.0/",
        "admin_username": "admin",
        "admin_password": "admin_pass",
        "admin_tenant_name": "demo"
      }, 
      "compute": {
        "controller_nodes_name": "192.168.1.3",
        "controller_node_ssh_user": "root_user",
        "controller_node_ssh_password": "root_password", 
        "path_to_private_key": "/local/path/to/the/private/key/of/node",
        "compute_nodes": "192.168.1.3"
      }
    }
  }, 

  "tests": {
    "verify": {
      "tests_to_run": []
    }, 
    "benchmark": {
      "tests_to_run": {
        "NovaServers.boot_and_delete_server": [
          {"args": {"flavor_id": 2, "image_id": "0d7cfe07-f684-4afa-813d-ca2611373c59"},
           "times": 2, "concurrent": 1},
          {"args": {"flavor_id": 2, "image_id": "0d7cfe07-f684-4afa-813d-ca2611373c59"},
           "times": 6, "concurrent": 2}
        ]
      }
    }
  }
}

DevStack deploys all OpenStack component on Vm2, actually in

  • "identity" section you should specify IP address of Server where Keystone is run
  • "compute" you should specify information about Server where works one of Nova Computes


Run Rally!

If you didn't create Rally DB you should run this command:

  openstack-rally-manage db recreate


Ok now we should run our rally with benchmark configuration:

 openstack-rally --verbose task start --task base_task.json

Now using another ssh connection to Rally VM. Run this command:

 oepnstack-rally task list 
 +--------------------------------------+----------------------------+-------------------------+--------+
 |                 uuid                 |         created_at         |          status         | failed |

 +--------------------------------------+----------------------------+-------------------------+--------+

To get detailed results by task with uuid: 83d9e08c-4f2b-4c1d-9c83-f36bcc6b5a68 you should run:

 openstack-rally task detailed  8532319f-d093-47de-b9f3-2909c03c7e30
 ================================================================================
 Task 83d9e08c-4f2b-4c1d-9c83-f36bcc6b5a68 is finished.
