=== Cluster Get Settings API

The Cluster Get Settings API allows to get the cluster wide settings.

[id="{upid}-{api}-request"]
==== Cluster Get Settings Request

A +{request}+:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------

==== Optional arguments
The following arguments can optionally be provided:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-includeDefaults]
--------------------------------------------------
<1> By default only those settings that were explicitly set are returned. Setting this to true also returns
the default settings.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-local]
--------------------------------------------------
<1> By default the request goes to the master of the cluster to get the latest results. If local is specified it gets
the results from whichever node the request goes to.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-masterTimeout]
--------------------------------------------------
<1> Timeout to connect to the master node as a `TimeValue`
<2> Timeout to connect to the master node as a `String`

[id="{upid}-{api}-response"]
==== Cluster Get Settings Response

The returned +{response}+ allows to retrieve information about the
executed operation as follows:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-response]
--------------------------------------------------
<1> Get the persistent settings.
<2> Get the transient settings.
<3> Get the default settings (returns empty settings if `includeDefaults` was not set to `true`).
<4> Get the value as a `String` for a particular setting. The order of searching is first in `persistentSettings` then in
`transientSettings` and finally, if not found in either, in `defaultSettings`.
