NAME

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

VERSION

10       version 6.00
11

DESCRIPTION

13       This module provides methods to make node-level requests, such as
14       retrieving node info and stats.
15
16       It does Search::Elasticsearch::Role::Client::Direct.
17

METHODS

19   "info()"
20           $response = $e->nodes->info(
21               node_id => $node_id | \@node_ids       # optional
22               metric  => $metric  | \@metrics        # optional
23           );
24
25       The "info()" method returns static information about the nodes in the
26       cluster, such as the configured maximum number of file handles, the
27       maximum configured heap size or the threadpool settings.
28
29       Allowed metrics are:
30           "http",
31           "jvm",
32           "network",
33           "os",
34           "plugin",
35           "process",
36           "settings",
37           "thread_pool",
38           "timeout",
39           "transport"
40
41       Query string parameters:
42           "error_trace",
43           "flat_settings",
44           "human"
45
46       See the node_info docs
47       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
48       nodes-info.html> for more information.
49
50   "stats()"
51           $response = $e->nodes->stats(
52               node_id      => $node_id    | \@node_ids       # optional
53               metric       => $metric     | \@metrics        # optional
54               index_metric => $ind_metric | \@ind_metrics    # optional
55           );
56
57       The "stats()" method returns statistics about the nodes in the cluster,
58       such as the number of currently open file handles, the current heap
59       memory usage or the current number of threads in use.
60
61       Stats can be returned for all nodes, or limited to particular nodes
62       with the "node_id" parameter. By default all metrics are returned, but
63       these can be limited to those specified in the "metric" parameter.
64
65       Allowed metrics are:
66           "_all",
67           "breaker",
68           "fs",
69           "http",
70           "include_segment_file_sizes",
71           "indices",
72           "jvm",
73           "network",
74           "os",
75           "process",
76           "thread_pool",
77           "timeout",
78           "transport"
79
80       If the "indices" metric (or "_all") is specified, then indices_stats
81       information is returned on a per-node basis. Which indices stats are
82       returned can be controlled with the "index_metric" parameter:
83
84           $response = $e->nodes->stats(
85               node_id       => 'node_1',
86               metric        => ['indices','fs']
87               index_metric  => ['docs','fielddata']
88           );
89
90       Allowed index metrics are:
91           "_all",
92           "completion"
93           "docs",
94           "fielddata",
95           "filter_cache",
96           "flush",
97           "get",
98           "id_cache",
99           "indexing",
100           "merge",
101           "percolate",
102           "query_cache",
103           "refresh",
104           "search",
105           "segments",
106           "store",
107           "warmer"
108
109       Query string parameters:
110           "completion_fields",
111           "error_trace",
112           "fielddata_fields",
113           "fields",
114           "groups",
115           "human",
116           "level",
117           "types"
118
119       See the stats docs
120       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
121       nodes-stats.html> for more information.
122
123   "hot_threads()"
124           $response = $e->nodes->hot_threads(
125               node_id => $node_id | \@node_ids       # optional
126           )
127
128       The "hot_threads()" method is a useful tool for diagnosing busy nodes.
129       It takes a snapshot of which threads are consuming the most CPU.
130
131       Query string parameters:
132           "error_trace",
133           "human",
134           "ignore_idle_threads",
135           "interval",
136           "snapshots",
137           "threads",
138           "timeout",
139           "type"
140
141       See the hot_threads docs
142       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
143       nodes-hot-threads.html> for more information.
144
145   "usage()"
146           $response = $e->nodes->usage(
147               node_id => $node_id | \@node_ids       # optional
148               metric  => $metric  | \@metrics        # optional
149           )
150
151       The "usage()" API retrieve sinformation on the usage of features for
152       each node.
153
154       Query string parameters:
155           "error_trace",
156           "human",
157           "timeout"
158
159       See the nodes_usage docs
160       <https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-
161       nodes-usage.html> for more information.
