## Parameters


### Query parameters
- **h** (string | array[string])
  A comma-separated list of columns names to display. It supports simple wildcards.

  Supported values include:
    - `id`: The node ID.
    - `host` (or `h`): The host name of the node.
    - `ip`: The IP address of the node.
    - `node` (or `n`): The node name.

- **s** (string | array[string])
  List of columns that determine how the table should be sorted.
  Sorting defaults to ascending and can be changed by setting `:asc`
  or `:desc` as a suffix to the column name.
- **local** (boolean)
  If `true`, the request computes the list of selected nodes from the
  local cluster state. If `false` the list of selected nodes are computed
  from the cluster state of the master node. In both cases the coordinating
  node will send requests for further information to each selected node.
- **master_timeout** (string)
  Period to wait for a connection to the master node.
