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。
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。
