前言

在前面的小节中,We explain in detail how to build oneHTTPInterface performance real-time monitoring test platform,使用Grafana+Influxdb+Jmeter的组合实现,In this section we continue the content of the previous section,Use another set of combinations,Grafana+Prometheus+Jmeter的方式实现,原理基本是一致的,只是配置稍有不同.好了,话不多说,我们开始.

正文

• Prometheus安装

• 创建Prometheus容器

• 命令：docker run -d --name prometheus-dsp --restart=always -p 9091:9090 -e "TZ=Asia/Shanghai" prom/prometheus

• 

  访问 Prometheus

• 使用http://ip+port

• 

   注意：If the following error occurs when creating a container,The external access port needs to be replaced,The premise is that the container that fails to be created needs to be deleted.

• 

• prometheus.yml配置文件中添加jmeter监控地址

  命令：docker exec -it prometheus-dsp sh

  使用vi编辑器修改prometheus.yml的配置文件,添加jmeter的配置监控,此处使用的ipThe address is usjmeter所在服务器的IP地址,端口为固定的9270端口,然后重启容器,我们的prometheusThe database server is set up,The configured monitoring address can be used subsequently,通过jmeter写入测试数据.

• 

  

• Grafana配置

How to create it was described in the previous chapterGrafana容器,This chapter will not introduce it！请参考（一）Build a real-time performance monitoring test platform（Grafana+Influxdb+Jmeter）本节中grafana的相关部分.

• 配置Prometheus数据源
•     
• 配置PrometheusMonitor monitoring templates
• 访问：Dashboards | Grafana Labs,Get monitoring templates 
•  下载Json文件和CopyID都行,这次就CopyID
•     

  deploy here,整个Grafana+Prometheus+JmeterThe configuration of the monitoring platform is complete

• 配置Jmeter插件

•  下载Prometheus的Jmeter插件
  下载地址：https://github.com/johrstrom/jmeter-prometheus-plugin/releases,这里我们下载0.5.2版本的.

• 

• 将下载的jar包jmeter-prometheus-plugin-0.5.2.jar放置在Jmeter目录的\apache-jmeter-5.0\lib\ext目录下

• 

• 启动Jmeter

• The previous chapter introduced how to configure pressure measurementJmeter

• 请参考：（一）Build a real-time performance monitoring test platform（Grafana+Influxdb+Jmeter）

• 注意：appears in the listenerPrometheus Listener说明插件安装成功,Reboot if not neededJmeter

• 添加一个Prometheus监听器

• 

  

• 点击jmeter开始测试按钮,访问http://localhost:9270/metrics地址
  如果出现如下内容,说明我们的jmeterData is ready to be collected,PrometheusIt is through this interface that our test data is collected,我们PrometheusThe configured monitoring address is here,It is used in the previous configurationIP地址,因为localhost只能本地访问.

• 

•  查看Prometheus,See if there is data written
• 进入Prometheus查看Status内TargetsMonitor whether the operation is successful,If there is a failure, it is very likelyprometheus.ymlThe internal address is not configured correctly

•  

• 查看Grafana监控面板 

• 结语

  ok,到这里,性能实时监控平台搭建（Grafana+Prometheus+Jmeter）及演示就完成了,我们下期见...
