NAME
Elasticsearch::Role::CxnPool::Sniff - A CxnPool role for connecting to a local cluster with a dynamic node list
VERSION
version 1.05
CONFIGURATION
sniff_interval
How often should we perform a sniff in order to detect whether new nodes have been added to the cluster. Defaults to `300` seconds.
sniff_max_content_length
Whether we should set the max_content_length dynamically while sniffing. Defaults to true unless a fixed max_content_length
was specified.
METHODS
schedule_check()
$cxn_pool->schedule_check
Schedules a sniff before the next request is processed.
parse_sniff()
$bool = $cxn_pool->parse_sniff(\%nodes);
Parses the response from a sniff request and extracts the hostname/ip of all listed nodes, filtered through "should_accept_node()". If any live nodes are found, they are passed to "set_cxns()" in Elasticsearch::Role::CxnPool. The max_content_length is also detected if "sniff_max_content_length" is true.
should_accept_node()
$host = $cxn_pool->should_accept_node($host,$node_id,\%node_data)
This method serves as a hook which can be overridden by the user. When a sniff is performed, this method is called with the host
(eg 192.168.5.100:9200
), the node_id
(the ID assigned to the node by Elasticsearch) and the node_data
which contains the information about the node that Elasticsearch has returned, eg:
{
"transport_address" => "inet[192.168.5.100/192.168.5.100:9300]",
"http" : {
"publish_address" => "inet[/192.168.5.100:9200]",
"max_content_length" => "100mb",
"bound_address" => "inet[/0:0:0:0:0:0:0:0:9200]",
"max_content_length_in_bytes" : 104857600
},
"version" => "0.90.4",
"name" => "Silver Sable",
"hostname" => "search1.domain.com",
"http_address" => "inet[/192.168.5.100:9200]"
}
If the node should be accepted (ie used to serve data), then it should return the host
value to use. By default, nodes are always accepted.
