Fortio负载测试库

Fortio

Fortio（Φορτίο）最初是Istio的负载测试工具，现在逐渐发展成为自己的项目。

Fortio也被Meshery等公司使用

Fortio以指定的每秒查询（qps）运行，记录执行时间的直方图并计算百分位数（例如p99，即99%的请求的响应时间小于该数字（以秒为单位，国际单位制））。它可以运行一个设定的持续时间、固定数量的调用，或者直到中断（以恒定的目标QPS，或者每个连接/线程的最大速度/负载）。

fortio这个名字来自希腊语φορτίο，意思是负荷/负荷。

Fortio是一个快速、小型（3Mb docker映像，最小依赖性）、可重用、可嵌入的go库以及命令行工具和服务器进程，服务器包括一个简单的web UI和结果的图形化表示（既有单个延迟图，也有多个结果比较最小值、最大值、平均值、qps和百分位图）。

Fortio还包括一组服务器端特性（类似于httpbin），以帮助调试和测试：请求回显（包括报头）、添加具有概率分布的延迟或错误代码、tcp代理、GRPC echo/health以及http等等。。。

Fortio相当成熟，非常稳定，没有已知的主要错误（如果你想贡献的话，还有很多可能的改进！），当发现错误时，它们会很快得到修复，因此经过1年的开发和42个增量版本，我们在2018年6月达到了1.0。

Installation

go get fortio.org/fortiofortio

或者使用docker，例如：

docker run -p 8080:8080 -p 8079:8079 fortio/fortio server & # For the server
docker run fortio/fortio load http://www.google.com/ # For a test run

或者从releases assets页面下载一个二进制发行版，例如：

curl -L https://github.com/fortio/fortio/releases/download/v1.6.8/fortio-linux_x64-1.6.8.tgz \
 | sudo tar -C / -xvzpf -
# or the debian package
wget https://github.com/fortio/fortio/releases/download/v1.6.8/fortio_1.6.8-1_amd64.deb
dpkg -i fortio_1.6.8-1_amd64.deb
# or the rpm
rpm -i https://github.com/fortio/fortio/releases/download/v1.6.8/fortio-1.6.8-1.x86_64.rpm

在MacOS上，您还可以使用自制软件安装Fortio：

brew install fortio

fortio server

Φορτίο 1.6.8 usage:
        fortio command [flags] target
where command is one of: load (load testing), server (starts grpc ping and
http echo/ui/redirect/proxy servers), grpcping (grpc client), report (report
only UI server), redirect (redirect only server), or curl (single URL debug).
where target is a url (http load tests) or host:port (grpc health test).
flags are:
  -H header
        Additional header(s)
  -L    Follow redirects (implies -std-client) - do not use for load test
  -P value

  -config path
        Config directory path to watch for changes of dynamic flags (empty for

  -data-dir Directory
        Directory where JSON results are stored/read (default ".")
  -echo-debug-path string

  -grpc
        Use GRPC (health check by default, add -ping for ping) for load testing

示例：打开2个额外的侦听端口，并将8888和8889（ipv6）上接收到的所有请求转发到8080（常规http服务器）

$ fortio server -P "8888 [::1]:8080" -P "[::1]:8889 [::1]:8080" 
Fortio 1.6.8 grpc 'ping' server listening on [::]:8079
Fortio 1.6.8 https redirector server listening on [::]:8081
Fortio 1.6.8 echo server listening on [::]:8080
Data directory is /home/dl
UI started - visit:
http://localhost:8080/fortio/
(or any host/ip reachable on this server)
Fortio 1.6.8 proxy for [::1]:8080 server listening on [::]:8888
Fortio 1.6.8 proxy for [::1]:8080 server listening on [::1]:8889

服务器URL和功能

server

curl -d abcdef http://localhost:8080/abcdef

还有GRPC health和ping服务器，以及http->https重定向器。

Implementation details

Fortio是用Go语言编写的，在stats.go中包含一个可伸缩的半日志柱状图，periodic.go中包含一个周期性的运行引擎，专门用于http和grpc。http/包包括一个非常高性能的专用http1.1客户端。你可能会发现fortio的记录器也很有用。
