简单介绍.Net性能测试框架Crank的使用方法

导读 这篇文章介绍了.Net性能测试框架Crank的使用方法。对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧

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。可参考Bombardier Job实现。

安装Crank

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\

创建Crank配置文件

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Crank-Agent

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'
启动Crank

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])

结果输出

这里省略压测期间的日志输出,直接列出结果。
