## 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。

||

## 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
|
||
}
|
||
}
|
||
}'
|
||
```
