This command groups subcommands for interacting with scaling policies. Scaling

Nomad targets.

List policies:
|
|

$ nomad scaling policy list

Detail an individual scaling policy:
|
|
|
|
$ nomad scaling policy info <policy_id>
|
|
|
|
Please see the individual subcommand help for detailed usage information.
