开始使用

使用一个 webservice 组件来开始，将下面的声明保存到 show-vegeta.yaml，并运行 vela up -f show-vegeta.yaml 来启动。

  1. apiVersion: core.oam.dev/v1beta1
  2. kind: Application
  3. metadata:
  4.   name: new-vegeta
  5.   namespace: vegeta
  6. spec:
  7.   components:

  15.           port: 80
  16.           protocol: TCP
  17.           ports: 80
  18.       traits:
  19.         - type: vegeta
  20.           properties:
  21.             dorequest: 'GET http://show-vegeta:80'
  22.             parallelism: 1
  23.             backofflimit: 10

  1. vela ls app -n vegeta

  • 如果你想获取一个更友好的输出，使用下面这两个工具： jaggr 和 jplot 来查看数据。
  1. kubectl logs new-vegeta--1-qrh67  -n vegeta -f | jaggr @count=rps hist\[100,200,300,400,500\]:code p25,p50,p95:latency sum:bytes_in sum:bytes_out | jplot rps+code.hist.100+code.hist.200+code.hist.300+code.hist.400+code.hist.500 latency.p95+latency.p50+latency.p25 bytes_in.sum+bytes_out.sum
