Available Benchmark Scenarios

Nova

NovaServers

This scenario class contains procedures concentrated on calling the Nova servers API.

boot_server

Boots one server.

Configuration example

  "NovaServers.boot_server":[
     {
        "args":{
           "flavor_id":2,
           "image_id":"539ccae5-5982-4868-b176-23c41ff1195e"
        },
        "times":8,
        "concurrent":4
     }
  ]

boot_and_bounce_server

Boots one server and then performs N "power operations" on it. The supported power operation actions are:

• stop_start -- Stop the VM and once stopped, start it and wait for it to become active.
• soft_reboot -- Perform a soft reboot of the VM and wait for it to come back up into the ACTIVE state.
• hard_reboot -- Perform a hard reboot of the VM and wait for it to come back into the ACTIVE state.

Note that the configuration format for this benchmark supports a list of power operations. So for example you could specify to stop_start the VM 5 times, followed by soft_boot it 2 times, followed by... These operations are defined in the 'actions' argument which is a list/array.

Configuration example

  "NovaServers.boot_and_bounce_server":[
     {
        "args":{
           "flavor_id":2,
           "image_id":"539ccae5-5982-4868-b176-23c41ff1195e",
           "actions":[
              {
                 "soft_reboot":4
              }
           ]
        },
        "times":31,
        "concurrent":8
     }
  ]

boot_and_delete_server

Boots and deletes one server.

Configuration example

  "NovaServers.boot_and_delete_server":[
     {
        "args":{
           "flavor_id":1,
           "image_id":"498c94c1-2547-4ddd-bea2-c5fc881b989f"
        },
        "times":50,
        "concurrent":10
     }
  ]

snapshot_server

Boots a server, makes its snapshot, then deletes the server and tries to boot it again from the saved snapshot. Finally deletes both the server and its snapshot.

Configuration example

  "NovaServers.snapshot_server":[
     {
        "args":{
           "flavor_id":1,
           "image_id":"498c94c1-2547-4ddd-bea2-c5fc881b989f"
        },
        "times":50,
        "concurrent":10
     }
  ]
