NAME

6       Search::Elasticsearch::Client::7_0::Direct::Cluster - A client for
7       running cluster-level requests
8

VERSION

10       version 7.30
11

DESCRIPTION

13       This module provides methods to make cluster-level requests, such as
14       getting and setting cluster-level settings, manually rerouting shards,
15       and retrieving for monitoring purposes.
16
17       It does Search::Elasticsearch::Role::Client::Direct.
18

METHODS

20   "health()"
21           $response = $e->cluster->health(
22               index   => 'index' | \@indices  # optional
23           );
24
25       The "health()" method is used to retrieve information about the cluster
26       health, returning "red", "yellow" or "green" to indicate the state of
27       the cluster, indices or shards.
28
29       Query string parameters:
30           "error_trace",
31           "human",
32           "level",
33           "local",
34           "master_timeout",
35           "timeout",
36           "wait_for_active_shards",
37           "wait_for_events",
38           "wait_for_no_initializing_shards",
39           "wait_for_no_relocating_shards",
40           "wait_for_nodes",
41           "wait_for_status"
42
43       See the cluster health docs
44       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
45       health.html> for more information.
46
47   "stats()"
48           $response = $e->cluster->stats(
49               node_id => 'node' | \@nodes     # optional
50           );
51
52       Returns high-level cluster stats, optionally limited to the listed
53       nodes.
54
55       Query string parameters:
56           "error_trace",
57           "flat_settings",
58           "human",
59           "timeout"
60
61       See the cluster stats docs
62       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
63       stats.html> for more information.
64
65   "get_settings()"
66           $response = $e->cluster->get_settings()
67
68       The "get_settings()" method is used to retrieve cluster-wide settings
69       that have been set with the "put_settings()" method.
70
71       Query string parameters:
72           "error_trace",
73           "flat_settings",
74           "human",
75           "include_defaults",
76           "master_timeout",
77           "timeout"
78
79       See the cluster settings docs
80       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
81       update-settings.html> for more information.
82
83   "put_settings()"
84           $response = $e->cluster->put_settings( %settings );
85
86       The "put_settings()" method is used to set cluster-wide settings,
87       either transiently (which don't survive restarts) or permanently (which
88       do survive restarts).
89
90       For instance:
91
92           $response = $e->cluster->put_settings(
93               body => {
94                   transient => { "discovery.zen.minimum_master_nodes" => 6 }
95               }
96           );
97
98       Query string parameters:
99           "error_trace",
100           "flat_settings",
101           "human"
102
103       See the cluster settings docs
104       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
105       update-settings.html>
106        for more information.
107
108   "state()"
109           $response = $e->cluster->state(
110               metric => $metric | \@metrics   # optional
111               index  => $index  | \@indices   # optional
112           );
113
114       The "state()" method returns the current cluster state from the master
115       node, or from the responding node if "local" is set to "true".
116
117       It returns all metrics by default, but these can be limited to any of:
118           "_all",
119           "blocks",
120           "metadata",
121           "nodes",
122           "routing_table"
123
124       Metrics for indices can be limited to particular indices with the
125       "index" parameter.
126
127       Query string parameters:
128           "allow_no_indices",
129           "error_trace",
130           "expand_wildcards",
131           "flat_settings",
132           "human",
133           "ignore_unavailable",
134           "local",
135           "master_timeout",
136           "wait_for_metadata_version",
137           "wait_for_timeout"
138
139       See the cluster state docs
140       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
141       state.html> for more information.
142
143   "allocation_explain()"
144           $response = $e->cluster->allocation_explain(
145               body => { ... shard selectors ...}  # optional
146           );
147
148       Returns information about why a shard is allocated or unallocated or
149       why.
150
151       Query string parameters:
152           "error_trace",
153           "human",
154           "include_disk_info",
155           "include_yes_decisions"
156
157       See the cluster allocation explain docs
158       <https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
159       allocation-explain.html> for more information.
160
161   "pending_tasks()"
162           $response = $e->cluster->pending_tasks();
163
164       Returns a list of cluster-level tasks still pending on the master node.
165
166       Query string parameters:
167           "error_trace",
168           "human",
169           "local",
170           "master_timeout"
171
172       See the pending tasks docs
173       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
174       pending.html> for more information.
175
176   "reroute()"
177           $e->cluster->reroute(
178               body => { commands }
179           );
180
181       The "reroute()" method is used to manually reallocate shards from one
182       node to another.  The "body" should contain the "commands" indicating
183       which changes should be made. For instance:
184
185           $e->cluster->reroute(
186               body => {
187                   commands => [
188                       { move => {
189                           index     => 'test',
190                           shard     => 0,
191                           from_node => 'node_1',
192                           to_node   => 'node_2
193                       }},
194                       { allocate => {
195                           index     => 'test',
196                           shard     => 1,
197                           node      => 'node_3'
198                       }}
199                   ]
200               }
201           );
202
203       Query string parameters:
204           "dry_run",
205           "error_trace",
206           "explain",
207           "human",
208           "master_timeout",
209           "metric",
210           "retry_failed",
211           "timeout"
212
213       See the reroute docs
214       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
215       reroute.html> for more information.
216
217   "remote_info()"
218           $response = $e->cluster->remote_info();
219
220       The "remote_info()" API retrieves all of the configured remote cluster
221       information.
222
223       Query string parameters:
224           "error_trace",
225           "human"
226
227       See the remote_info docs
