入门篇我们已经成功运行hello.benchmarks.yml并输出测试结果,本篇我们就hello.benchmarks.yml、以及运行的shell脚本详细解读下其中的含义
在hello.benchmarks.yml中我们定义了一个新的job: server,并指定了仓库信息 ( 远程仓库 ):
repository:https://github.com/doddgu/crank.git # 仓库源
branchOrCommit:sample # 分支
project: samples/hello/hello.csproj # 项目
并通过import导入了bombardier.yml,其中定义了另外一个job: bombardier,并指定了仓库信息 ( 远程仓库 ):
repository: https://github.com/doddgu/crank.git
branchOrCommit: sample
project: src/Microsoft.Crank.Jobs.Bombardier/Microsoft.Crank.Jobs.Bombardier.csproj
sourceKey: bombardier # 服务器使用它来重用相同的源文件夹。
noBuild: true # 定义 SourceKey时,指示是否仍应进行构建
在hello.benchmarks.yml中我们定义了场景: hello,并为此场景指定了两个任务:
在bombardier.yml中
在hello.benchmarks.yml中为load定义了局部变量serverPort、path
在hello.benchmarks.yml中我们
在bombardier.yml中与variables同级的配置: arguments,此参数是在启动job后传递的参数,其中定义的全局参数、局部参数信息也都是为构建完整的参数做准备,bombardier真实的参数信息是:
-c {{connections}} -w {{warmup}} -d {{duration}} -n {{requests}} --insecure -l {% if rate != 0 %} --rate {{ rate }} {% endif %} {% if transport %} --{{ transport}} {% endif %} {{headers[presetHeaders]}} {% for h in customHeaders %}{% assign s = h | split : ':' %}--header \"{{ s[0] }}: {{ s[1] | strip }}\" {% endfor %} {% if serverUri == blank or serverUri == empty %} {{serverScheme}}://{{serverAddress}}:{{serverPort}}{{path}} {% else %} {{serverUri}}:{{serverPort}}{{path}} {% endif %} {% if bodyFile != blank and bodyFile != empty %} -f {{bodyFile}} {% endif %} {% if verb != blank and verb != empty %} -m {{verb}} {% endif %}
改造hello.benchmarks.yml,不考虑重用,最原始的代码如下
variables:
headers:
none: ''
plaintext: '--header "Accept: text/plain,text/html;q=0.9,application/xhtml+xml;q=0.9,application/xml;q=0.8,*/*;q=0.7" --header "Connection: keep-alive"'
html: '--header "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8" --header "Connection: keep-alive"'
json: '--header "Accept: application/json,text/html;q=0.9,application/xhtml+xml;q=0.9,application/xml;q=0.8,*/*;q=0.7" --header "Connection: keep-alive"'
connectionclose: '--header "Connection: close"'
presetHeaders: none
jobs:

arguments: "-c {{connections}} -w {{warmup}} -d {{duration}} -n {{requests}} --insecure -l {% if rate != 0 %} --rate {{ rate }} {% endif %} {% if transport %} --{{ transport}} {% endif %} {{headers[presetHeaders]}} {% for h in customHeaders %}{% assign s = h | split : ':' %}--header \"{{ s[0] }}: {{ s[1] | strip }}\" {% endfor %} {% if serverUri == blank or serverUri == empty %} {{serverScheme}}://{{serverAddress}}:{{serverPort}}{{path}} {% else %} {{serverUri}}:{{serverPort}}{{path}} {% endif %} {% if bodyFile != blank and bodyFile != empty %} -f {{bodyFile}} {% endif %} {% if verb != blank and verb != empty %} -m {{verb}} {% endif %}"
onConfigure:
# - job.timeout = Number(job.variables.duration) + Number(job.variables.warmup) + 10;

之前我们通过shell执行:
crank --config hello.benchmarks.yml --scenario hello --profile local --load.framework net5.0 --application.framework net5.0
改造hello.benchmarks.yml,因为移除了profile,所以执行: crank --config hello.yml --scenario hello --load.framework net5.0 --application.framework net5.0 即可
为什么启动crank时要增加--application.framework net5.0?
为什么启动crank时不指定framework时默认是netcore3.1呢?
scenarios节点下application以及load两个节点名称可以更换吗?只能有两个节点?
通过上面的学习,我们也已经完全的了解了各配置的作用,但对bombardier.yml与开源项目bombardier存在什么样的联系还不清楚,以及为什么叫做bombardier.yml而不是其他名字,并且是如何实现性能指标的输出,接下来就会讲到bombardier.yml与开源项目bombardier的关系,以及wrk.yml与wrk的关系
