### prometheus+cadvisor监控docker容器 ###

##### 首先在docker宿主机上安装cadvisor #####

docker通过cadvisor监控 在宿主机上使用如下命令 可以直接通过ip+port 进入cadvisor的web界面查看

docker run -d -it -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 --privileged=true --name=cadvisor  --net=host  -v "/etc/localtime:/etc/localtime" --restart=always  google/cadvisor:v0.33.0

##### 在宿主机上安装node\_exporter #####

useradd prometheus
    NODE_PATH='/srv/prometheus/node_exporter/'
    cd /usr/local/src/
    mkdir -p ${NODE_PATH}
    wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz 
    tar -xvf node_exporter-0.18.1.linux-amd64.tar.gz
    cp node_exporter-0.18.1.linux-amd64/node_exporter ${NODE_PATH}
    chown -R prometheus.prometheus ${NODE_PATH}
    
    cat > /lib/systemd/system/node_exporter.service <<EOF [Unit] Description=node_exporter Documentation=https://prometheus.io/ After=network.target [Service] Type=simple User=prometheus ExecStart=/srv/prometheus/node_exporter/node_exporter Restart=on-failure [Install] WantedBy=multi-user.target EOF
    
    systemctl daemon-reload
    systemctl enable node_exporter.service
    systemctl start node_exporter.service
    systemctl status node_exporter.service
    
    netstat -plntu |grep 9100

##### 备份并修改原先的prometheus 添加一个新的job\_name #####

- job_name: 'docker'
        static_configs:
        - targets: ['192.168.10.97:8080', '192.168.10.97:9100']  ## 目标主机

##### 重启prometheus #####

systemctl  restart prometheus
    systemctl  status prometheus

##### 在grafana里导入模版10566 #####

导入之后 大致如下所示 部分参数需要自己手动调。红框框里的是宿主机信息 其实可以去掉，放到专门监控宿主机的模版里。

部分监控项需要调整 截图提供一些参考
