Work with nested fields in logstash elasticsearch filter

hello!

i want to enrich my data with the elastic filter .

i tried to keep de host.hostname fields of metricbeat without success with this:

elasticsearch {
    hosts => "https://xxxx:9200"
    index => "metricbeat"
    query => "[host][hostname]:%{server}"
    fields => { "[host][hostname]" => "server" }
    user => "yyyyy"
    password => "xxxxx"
    ca_file => 'xxxx/elasticsearch-ca.pem'
}

i tried it with host.hostname, host, hostname, [host.hostname], etc...

how does this filter works with nested fields?

thanks in advanced!

Untested. But try this.

    query => "host.hostname:%{[server]}"
    fields => { "host.hostname" => "server" }

This is based off previous filter I wrote.

filter {
  elasticsearch {
    hosts => ["localhost:9200"]
    index => "lookup"
    query => "_id:%{[kibana.saved_object.type]}\:%{[kibana.saved_object.id]}"
    fields => { "visualization.title" => "kibana.saved_object.title" }
    enable_sort => false
  }    
}
