## 为啥写这个工具
当我在做后端开发或者写 [go-zero](https://github.com/zeromicro/go-zero) 的时候，经常会需要监控网络连接，分析请求内容。比如：
1. 分析 gRPC 连接何时连接、何时重连
2. 分析 MySQL 连接池，当前多少连接，连接的生命周期是什么策略
3. 也可以用来观察和分析任何 TCP 连接
## 安装
```shell
$ GOPROXY=https://goproxy.cn/,direct go install github.com/kevwan/tproxy@latest
```
或者使用 docker 镜像：
```shell
$ docker run --rm -it -p : -p : kevinwan/tproxy:v1 tproxy -l 0.0.0.0 -p -r host.docker.internal:
```
arm64 系统:
```shell
$ docker run --rm -it -p : -p : kevinwan/tproxy:v1-arm64 tproxy -l 0.0.0.0 -p -r host.docker.internal:
```
Windows:
```shell
$ scoop install tproxy
```
## 用法
```shell
$ tproxy --help
Usage of tproxy:
-d duration
the delay to relay packets
-down int
Downward speed limit(bytes/second)
-l string
Local address to listen on (default "localhost")
-p int
Local port to listen on, default to pick a random port
-q Quiet mode, only prints connection open/close and stats, default false
-r string
Remote address (host:port) to connect
-s Enable statistics
-t string
The type of protocol, currently support http2, grpc, redis and mongodb
-up int
Upward speed limit(bytes/second)
```
## 示例
### 分析 gRPC 连接
```shell
$ tproxy -p 8088 -r localhost:8081 -t grpc -d 100ms
```
- 侦听在 localhost 和 8088 端口
- 重定向请求到 `localhost:8081`
- 识别数据包格式为 gRPC
- 数据包延迟100毫秒
### 分析 MySQL 连接
```shell
$ tproxy -p 3307 -r localhost:3306
```
### 查看网络状况（重传率和RTT）
```shell
$ tproxy -p 3307 -r remotehost:3306 -s -q
```
### 查看连接池（总连接数、最大并发连接数、最长生命周期等）
```shell
$ tproxy -p 3307 -r :3306 -s -q
```
