### Query Parameters
|
|

|
|
|
|
|
|
|
- `global` `(bool: false)` - If present, usage information for all

|
known datacenters will be returned. By default, only the local datacenter's
|
|
|
|
|
usage information is returned.
|
|
|
|
|
|
|
|
|
|
- `stale` `(bool: false)` - If the cluster does not currently have a leader, an

|
|
|
Raft configuration from any of the Consul servers.
