如何使用 Logstash 从 Elasticsearch 获取数据并将其放入 Graphite？

Question

我有 logstash.conf 文件，我从 MySQL 数据库中获取数据。但现在我必须从 Elasticsearch 获取数据并将其放入 Graphite。有我的代码logstash.conf:

input {
     jdbc {
            type => "some type"
            jdbc_driver_library => "sqljdbc42.jar"
            jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
            jdbc_connection_string => "jdbc:sqlserver://host:port;databaseName=db name"
            jdbc_user =>  "username"
            jdbc_password => "***"
            jdbc_default_timezone => "Asia/Almaty"
            statement_filepath => "sqlscript.sql"
            schedule => "*/30 * * * *"
     }
}

output {

    stdout { codec => json }

    if [type] == "some type"  {

     graphite {
        host => "some host"
        port => port
        metrics => [some.metric", "%{cnt}"]
     }

    }
}

Answer 1

您需要做的就是将 logstash.conf 中的输入配置更改为：

elasticsearch {
  hosts => "localhost"
  query => '{ "query": { "match_all": {} }, "sort": [ "_doc" ] }'
}

Just use elasticsearch input for logstash.
