NAME

       Search::Elasticsearch::Client::1_0::Direct::Nodes - A client for running node-level
       requests

VERSION

       version 6.81

DESCRIPTION

       This module provides methods to make node-level requests, such as retrieving node info and
       stats.

       It does Search::Elasticsearch::Role::Client::Direct.

METHODS

   "info()"
           $response = $e->nodes->info(
               node_id => $node_id | \@node_ids       # optional
               metric  => $metric  | \@metrics        # optional
           );

       The "info()" method returns static information about the nodes in the cluster, such as the
       configured maximum number of file handles, the maximum configured heap size or the
       threadpool settings.

       Allowed metrics are:
           "http",
           "jvm",
           "network",
           "os",
           "plugin",
           "process",
           "settings",
           "thread_pool",
           "transport"

       Query string parameters:
           "flat_settings",
           "human"

       See the node_info docs
       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-info.html>
       for more information.

   "stats()"
           $response = $e->nodes->stats(
               node_id      => $node_id    | \@node_ids       # optional
               metric       => $metric     | \@metrics        # optional
               index_metric => $ind_metric | \@ind_metrics    # optional
           );

       The "stats()" method returns statistics about the nodes in the cluster, such as the number
       of currently open file handles, the current heap memory usage or the current number of
       threads in use.

       Stats can be returned for all nodes, or limited to particular nodes with the "node_id"
       parameter. By default all metrics are returned, but these can be limited to those
       specified in the "metric" parameter.

       Allowed metrics are:
           "_all",
           "breaker",
           "fs",
           "http",
           "indices",
           "jvm",
           "network",
           "os",
           "process",
           "thread_pool",
           "transport"

       If the "indices" metric (or "_all") is specified, then indices_stats information is
       returned on a per-node basis. Which indices stats are returned can be controlled with the
       "index_metric" parameter:

           $response = $e->cluster->node_stats(
               node_id       => 'node_1',
               metric        => ['indices','fs']
               index_metric  => ['docs','fielddata']
           );

       Allowed index metrics are:
           "_all",
           "completion"
           "docs",
           "fielddata",
           "filter_cache",
           "flush",
           "get",
           "id_cache",
           "indexing",
           "merge",
           "percolate",
           "query_cache",
           "refresh",
           "search",
           "segments",
           "store",
           "warmer"

       Query string parameters:
           "completion_fields",
           "fielddata_fields",
           "fields",
           "groups",
           "human",
           "level",
           "types"

       See the node_stats docs
       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-stats.html>
       for more information.

   "hot_threads()"
           $response = $e->nodes->hot_threads(
               node_id => $node_id | \@node_ids       # optional
           )

       The "hot_threads()" method is a useful tool for diagnosing busy nodes. It takes a snapshot
       of which threads are consuming the most CPU.

       Query string parameters:
           "ignore_idle_threads",
           "interval",
           "snapshots",
           "threads",
           "type"

       See the hot_threads docs
       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-hot-
       threads.html> for more information.

   "shutdown()"
           $e->nodes->shutdown(
               node_id => $node_id | \@node_ids    # optional
           );

       The "shutdown()" method is used to shutdown one or more nodes, or the whole cluster.

       Query string parameters:
           "delay",
           "exit"

       See the shutdown docs
       <http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-
       shutdown.html> for more information.
