HJ3-24.7 性能监控体系实战

配置 Prometheus

• Prometheus 是一款开源系统监控和警报工具。使用 Go 语言开发，有各种 exporter 用来收集服务器性能数据。
• 我们通过Promethues 来监控压测时服务端的性能。

部署 Prometheus

• 配置文件：https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus.yml
• 运行：

  docker run -d --name prometheus --network grafana -p 9090:9090 -v ${PWD}/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus:v2.16.0 --config.file=/etc/prometheus/prometheus.yml
  

./node_exporter --help
./node_exporter --web.listen-address=":9102"
nohup ./node_exporter --web.listen-address=":9102" &
cat nohup.out

vim prometheus.yml
- job_name:'CentOS 192.168.31.61'
  static_configs:
  - targets:['192.168.31.61:9102']

docker restart prometheus
