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": 1, "image_id": "73257560-c59b-4275-a1ec-ab140e5b9979"},
           "execution": "continuous",
           "config": {"times": 8, "active_users": 4, "tenants": 2, "users_per_tenant": 2}
       }
   ]

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": 1,
               "image_id": "73257560-c59b-4275-a1ec-ab140e5b9979",
               "actions" : [{"soft_reboot": 4}, {"stop_start": 2}]
           },
           "execution": "continuous",
           "config": {"times": 31, "active_users": 8}
       }
   ]

boot_and_delete_server

Boots and deletes one server.

Configuration example

   "NovaServers.boot_and_delete_server": [
       {
           "args": {"flavor_id": 1, "image_id": "73257560-c59b-4275-a1ec-ab140e5b9979"},
           "execution": "continuous",
           "config": {"duration": 30, "active_users": 10, "tenants": 3, "users_per_tenant": 5}
       }
   ]

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": "73257560-c59b-4275-a1ec-ab140e5b9979"},
           "execution": "continuous",
           "config": {"times": 50, "active_users": 10, "tenants": 3, "users_per_tenant": 5}
       }
   ]

Benchmark Scenario Wishlist
