容器化部署prometheus后再监控docker容器_prometheus监控容器应用-优快云博客

一、主机部署Prometheus、cadvisor、grafana、node-exporter

1、部署cadvisor收集节点容器信息
docker run -v /:/rootfs:ro -v /var/run:/var/run/:rw -v /sys:/sys:ro -v /var/lib/docker:/var/lib/docker:ro -p 8080:8080 --detach=true --name=cadvisor  google/cadvisor
2、部署node-EXporter,收集硬件和系统信息
docker run -d -p 9100:9100 -v /proc:/host/proc -v /sys:/host/sys -v /:/rootfs prom/node-exporter --path.procfs /host/proc --path.sysfs /host/sys --collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)"
3、部署prometheus-server服务
先启动一个prometheus服务，目的是复制他的配置文件，修改配置文件，prometheus挂载这个文件
mkdir /prometheus
docker run -d --name test -P prom/prometheus
docker cp test:/etc/prometheus/prometheus.yml /prometheus
#编辑prometheus配置文件
#以下添加的ip都将会被监控起来
global:
  scrape_interval:    15s
  evaluation_interval: 15s

scrape_configs:
- job_name: prometheus
  static_configs:
  - targets: ['10.10.80.167:9090','10.10.80.167:8080']
    labels:
      instance: centos7

- job_name: localhost
  static_configs:
  - targets: ['10.10.80.167:9100']
    labels:
      instance: centos7

- job_name: jumpserver
  static_configs:
  - targets: ['10.10.200.15:9100','10.10.200.15:8080']
    labels:
      instance: jumpserver

重新运行prometheus服务

收集cAdvisor和nodexporter的信息到prometheus
docker rm -f test
docker run -d --name prometheus --net host -p 9090:9090 -v /prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus


4、部署grafana
mkdir /grafana
chmod 777 -R /grafana
docker run -d -p 3000:3000 --name grafana -v /grafana:/var/lib/grafana -e "GF_SECURITY_ADMIN_PASSWORD=123.com" grafana/grafana

访问测试，默认账号密码：admin，admin

添加数据源

填入prometheus地址，保存退出

2、被监控主机上部署node-exporter，cadvisor

#从监控主机上将node-exporter镜像，cadvisor镜像导出，然后在客户端上导入。(也可以直接按上述命令下载)
客户端IP地址：10.10.200.245  10.10.200.246   10.10.200.15
/usr/local/bin/docker load -i cadvisor.tar.gz
/usr/local/bin/docker load -i node.tar.gz
导入镜像后，启动容器
/usr/local/bin/docker run -d -p 9100:9100 -v /proc:/host/proc -v /sys:/host/sys -v /:/rootfs prom/node-exporter --path.procfs /host/proc --path.sysfs /host/sys --collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)"

/usr/local/bin/docker run -v /:/rootfs:ro -v /var/run:/var/run/:rw -v /sys:/sys:ro -v /var/lib/docker:/var/lib/docker:ro -p 8080:8080 --detach=true --name=cadvisor 
google/cadvisor

容器启动正常后，回到prometheus服务端，修改配置文件
[root@localhost ~]# vim /opt/prometheus/prometheus.yml
global:
  scrape_interval:    15s
  evaluation_interval: 15s

scrape_configs:
- job_name: prometheus
  static_configs:
  - targets: ['10.10.80.167:9090','10.10.80.167:8080']
    labels:
      instance: centos7

- job_name: localhost
  static_configs:
  - targets: ['10.10.80.167:9100']
    labels:
      instance: centos7
- job_name: jumpserver
  static_configs:
  - targets: ['10.10.200.15:9100','10.10.200.15:8080']
    labels:
      instance: jumpserver
- job_name: FileZ-245
  static_configs:
  - targets: ['10.10.200.245:9100','10.10.200.245:8080']
    labels:
      instance: FileZ-245
- job_name: FileZ-246
  static_configs:
  - targets: ['10.10.200.246:9100','10.10.200.246:8080']
    labels:
      instance: FileZ-246
