Logstash 不要在我的储藏室里炒菜

配置文件：

# input are the kafka messages
input
{
    kafka
    {
        topic_id => 'test2'
    }
}

# Try to match sensor info
filter
{
    json { source => "message"}
}

# StatsD and stdout output
output
{
    stdout
    {
        codec => line
        {
            format => "%{[testmessage][0][key]}"
        }
    }

    stdout { codec=>rubydebug }

    statsd
    {
        host => "localhost"
        port => 8125
        increment => ["test.%{[testmessage][0][key]}"]
    }
}

输入卡夫卡消息：

{"testmessage":[{"key":"key-1234"}]}

输出：

key-1234
{
    "testmessage" => [
        [0] {
            "key" => "key-1234"
        }
    ],
       "@version" => "1",
     "@timestamp" => "2015-11-09T20:11:52.374Z"
}

为什么statsd不能在我的logstash中工作。看看谷歌的很多例子，不知道为什么。欢迎提出任何建议。谢谢。

我找到了原因，logstash output statsd默认使用UDP。但是我的statsd服务器设置为使用TCP
