# go-pprof-tool

golang pprof性能分析监控工具使用

# Usages

提供两种方式

+ http接口访问

+ 采集到文件

## http接口访问

```

import (

	"github.com/handsomestWei/go-pprof-tool/pprof"

)

// 暴露端口提供http接口访问

pprof.RunAtAddrAndPort("addr:port")

```

采集信息页面

```

http://addr:port/debug/pprof/

```

下载采集文件

```

go tool pprof http://addr:port/debug/pprof/profile?seconds=30

```

## 采集到文件

```

import (

	"github.com/handsomestWei/go-pprof-tool/pprof"

)

// 指定采集文件输出目录，和采集持续时间

pprof.Dump2FileDuration("./cpu.prof", 10*time.Second)

```

打开采集文件

```

go tool pprof [filePath]

```

## 采集文件解析

```

go tool pprof [filePath] [command]

```

### top命令

关注sum%列：给定函数累积使用cpu总比例

### list命令

定位到可能有问题的代码段

```

list [function name]

例：list BlockDefault

```

### web命令

[需要安装工具](http://www.graphviz.org/download/)

生成调用链

### exit命令

退出
