## 定义

`udp-logger` 是用于将日志数据发送到UDP服务的插件。

以实现将日志数据以JSON格式发送到监控工具或其它UDP服务的能力。

此插件提供了将批处理数据批量推送到外部UDP服务器的功能。如果您没有收到日志数据，请放心一些时间，它会在我们的批处理处理器中的计时器功能到期后自动发送日志

有关Apache APISIX中Batch-Processor的更多信息，请参考。
[Batch-Processor](../../batch-processor.md)

## 如何开启

1. 下面例子展示了如何为指定路由开启 `udp-logger` 插件的。

```shell
curl http://127.0.0.1:9080/apisix/admin/routes/5 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
      "plugins": {
            "udp-logger": {
                 "host": "127.0.0.1",
                 "port": 3000,
                 "batch_max_size": 1,
                 "name": "udp logger"
            }
       },
      "upstream": {
           "type": "roundrobin",
           "nodes": {
               "127.0.0.1:1980": 1
           }
      },
      "uri": "/hello"
}'
```

## 测试插件

* 成功的情况:

```shell
$ curl -i http://127.0.0.1:9080/hello
HTTP/1.1 200 OK
...
hello, world
```

## 禁用插件

想要禁用“udp-logger”插件，是非常简单的，将对应的插件配置从json配置删除，就会立即生效，不需要重新启动服务：

```shell
$ curl http://127.0.0.1:2379/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d value='
{
    "methods": ["GET"],
    "uri": "/hello",
    "plugins": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    }
}'
```
