NAME

6       Search::Elasticsearch::Role::CxnPool::Sniff - A CxnPool role for
7       connecting to a local cluster with a dynamic node list
8

VERSION

10       version 6.81
11

CONFIGURATION

13   "sniff_interval"
14       How often should we perform a sniff in order to detect whether new
15       nodes have been added to the cluster.  Defaults to `300` seconds.
16
17   "sniff_max_content_length"
18       Whether we should set the max_content_length dynamically while
19       sniffing. Defaults to true unless a fixed "max_content_length" was
20       specified.
21

METHODS

23   "schedule_check()"
24           $cxn_pool->schedule_check
25
26       Schedules a sniff before the next request is processed.
27
28   "parse_sniff()"
29           $bool = $cxn_pool->parse_sniff(\%nodes);
30
31       Parses the response from a sniff request and extracts the hostname/ip
32       of all listed nodes, filtered through "should_accept_node()". If any
33       live nodes are found, they are passed to "set_cxns()" in
34       Search::Elasticsearch::Role::CxnPool.  The max_content_length is also
35       detected if "sniff_max_content_length" is true.
36
37   "should_accept_node()"
38           $host = $cxn_pool->should_accept_node($host,$node_id,\%node_data)
39
40       This method serves as a hook which can be overridden by the user.  When
41       a sniff is performed, this method is called with the "host" (eg
42       "192.168.5.100:9200"), the "node_id" (the ID assigned to the node by
43       Elasticsearch) and the "node_data" which contains the information about
44       the node that Elasticsearch has returned, eg:
45
46           {
47               "transport_address" => "inet[192.168.5.100/192.168.5.100:9300]",
48               "http" : {
49                  "publish_address"    => "inet[/192.168.5.100:9200]",
50                  "max_content_length" => "100mb",
51                  "bound_address"      => "inet[/0:0:0:0:0:0:0:0:9200]",
52                  "max_content_length_in_bytes" : 104857600
53               },
54               "version"       => "0.90.4",
55               "name"          => "Silver Sable",
56               "hostname"      => "search1.domain.com",
57               "http_address"  => "inet[/192.168.5.100:9200]"
58           }
59
60       If the node should be accepted (ie used to serve data), then it should
61       return the "host" value to use.  By default, nodes are always accepted.
