英文:
Go pprof: Got Error unrecognized profile format
问题
我正在使用Go revel框架（我的Go版本是1.6.2）开发一个Web程序。我在内存使用方面遇到了问题。Revel占用的内存每天几乎增加了几百MB。因此，我想对程序进行调优。然后我学习了如何使用go pprof，并按照github.com/revel/modules/tree/master/pprof中所说使用了revel pprof。但是，当我尝试使用以下命令获取内存分析时：
go tool pprof http://sit:9000/debug/pprof/heap.
它报错说无法识别的分析格式。你可以看到下面的截图。

我已经为这个问题苦苦挣扎了几个小时。非常感谢你提供的任何帮助！提前谢谢！

So I want to tune the program. Then I learn to use the go pprof and use the revel pprof as said in github.com/revel/modules/tree/master/pprof. But while I'm trying to get the memory profile with following command
> go tool pprof http://sit:9000/debug/pprof/heap.
It got error unrecognized profile format. You can see as following snapshot.

I've struggled on this issue for hours. Any help is appreciated! Thank you in advance!

很可能是因为你的调试配置文件是空的。
你需要使用SetBlockProfileRate函数来指定应用程序的分析频率。
https://golang.org/pkg/runtime/#SetBlockProfileRate
只需在你的main文件中导入runtime包，并调用runtime.SetBlockProfileRate函数。
或者，你可以使用这个包，它会为你处理一些默认设置：https://github.com/pkg/profile
英文:
It's most likely because your debug profile is empty.
You need to specify how often to profile the app using SetBlockProfileRate
https://golang.org/pkg/runtime/#SetBlockProfileRate
Just import the runtime package in your main file and call the runtime.SetBlockProfileRate function.
Alternatively, you can use this package, which handles it for you, with some defaults: https://github.com/pkg/profile
