docker pull prom/prometheus准备配置文件prometheus.yml${host1}、${host2}为变量例如可以替换为localhost:8080scrape_configs:
# 可随意指定
- job_name: spring# 多久采集一次数据scrape_interval: 15s# 采集时的超时时间scrape_timeout: 10s# 采集的路径metrics_path: /actuator/prometheus# 采集服务的地址设置成Springboot应用所在服务器的具体地址static_configs:- targets: [${host1},${host2}]启动--log.leveldebug日志以debug输出--storage.tsdb.retention.time3d数据保留3天--config.file/etc/prometheus/prometheus.yml容器里面的默认路径docker run -d -p 9090:9090 -v /root/docker-images/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml --name prometheus prom/prometheus:latest --log.leveldebug --storage.tsdb.retention.time3d --config.file/etc/prometheus/prometheus.yml或者启动脚本docker run -d -p 9090:9090 -v /root/docker-images/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml --name prometheus prom/prometheus:latest --config.file/etc/prometheus/prometheus.yml启动成功后访问地址http://${ip}:9090/页面展示3.2 Grafana安装拉去镜像docker pull grafana/grafana运行示例docker run -d -p 3000:3000 grafana/grafana访问地址http://localhost:3000账号admin密码admin页面展示3.3 Grafana配置Prometheus数据源1Date Sources-- 选择 Prometheus配置 Name 和 URL注意Name必须为首字母大写Prometheus不能全写成小写的prometheus。因为Prometheus和Grafana都是docker安装所以url需要写外网地址。2新建 DashboardCreate Dashboard配置title、description配置Data Source选择指标保存3.4 模板套用Grafana提供了许多优秀的模板可以网页https://grafana.com/grafana/dashboards 查找。导入模板id复制模板id导入导入后可以看到监控效果了
