Crank 是微软新出的一个性能测试框架,集成了多种基准测试工具,如bombardier、wrk等。
Crank通过统一的配置,可以转换成不同基准测试工具命令进行测试。
运行如下两个命令分别安装Crank
的cli(Controller)
和Agent
。
dotnet tool update Microsoft.Crank.Controller --version "0.2.0-*" --global dotnet tool update Microsoft.Crank.Agent--version "0.2.0-*" --global
需要.Net SDK 5.0环境
安装完成后执行命令crank
,会打印出如下可以配置的参数和介绍,或者github查看相关参数介绍。
PS C:\Users\Stack\Desktop> crank Crank Benchmarks Controller The Crank controller orchestrates benchmark jobs on Crank agents. Usage: Crank [command] [options] Options: -?|-h|--help Show help information -c|--config Configuration file or url -s|--scenario Scenario to execute -j|--job Name of job to define --profile Profile name --script Execute a named script available in the configuration files. Can be used multiple times. -j|--json Saves the results as json in the specified file. --csv Saves the results as csv in the specified file. --compare An optional filename to compare the results to. Can be used multiple times. --variable Variable --sql Connection string of the SQL Server Database to store results in --table Table name of the SQL Database to store results in --session A logical identifier to group related jobs. --description A string describing the job. -p|--property Some custom key/value that will be added to the results, .e.g. --property arch=arm --property os=linux
执行crank-agent
,启动基准测试所需的代理服务。github查看相关参数介绍。
PS C:\Users\Stack\Desktop> crank-agent Hosting environment: Production Content root path: C:\Users\Stack\.dotnet\tools\.store\microsoft.crank.agent\0.2.0-alpha.21567.1\microsoft.crank.agent\0.2.0-alpha.21567.1\tools\net5.0\any\ Now listening on: http://[::]:5010
配置文件参考官方hello.benchmarks.yml示例
示例文件中引入了bombardier.yml
,由于大环境对githubusercontent.com域名不太友好,可以考虑将bombardier.yml
下载到本地,imports
引入本地路径或者直接将文件内容加入到新建的配置文件。
imports: -https://raw.githubusercontent.com/dotnet/crank/main/src/Microsoft.Crank.Jobs.Bombardier/bombardier.yml
生产中使用推荐imports文件的方式,crank配置文件中做少量配置就可以完成基准测试,并且可以引入不同的Microsoft.Crank.Jobs.XXX/XXX.yml,基于不同的基准测试工具进行测试。
其他测试工具配置文件都在https://github.com/dotnet/crank/blob/main/src/Microsoft.Crank.XXX下。

启动agent
后执行crank
,会有一个如下安装sdk的动作
[09:29:05.261] Runtime: 6.0.0 (Current) [09:29:05.262] SDK: 6.0.100 (Current) [09:29:05.263] ASP.NET: 6.0.0 (Current) [09:29:05.265] Creating custom global.json [09:29:05.266] Desktop: 6.0.0 (Current) [09:29:05.266] Installing SDK '6.0.100' ...
所以启动agent
时多指定一个dotnethome
参数,避免重复安装sdk。
crank-agent --dotnethome 'C:\Program Files\dotnet'
crank --config .\demo.benchmarks.yml --scenario crank_demo --profile local
--scenario crank_demo
: 指定定义的测试场景
--profile local
:设置输出结果到本地,即控制台输出
可以通过参数指定结果输出到本地json文件(--output results.json )或者数据库(--sql [connection-string] --table [table-name])
这里省略压测期间的日志输出,直接列出结果。
