- `-datacenter=<name>` - Name of the datacenter to query. If unspecified, the query will default to the datacenter of the Consul agent at the HTTP address. - `-stale` - Permit any Consul server (non-leader) to respond to this request. This allows for lower latency and higher throughput, but can result in stale data. This option has no effect on non-read operations. The default value is false.
