1.环境

192.168.244.128 Prometheus 监控服务器 192.168.244.129 docker 服务（被监控端） 注：都是centos7.5系统

2.下载安装包

（需要的安装包都可以下载） wget

服务端（监控server）

3.安装prometheus 部署到/usr/local/目录 promethus不用编译安装，解压目录中有配置文件与启动文件 tar -zxvf prometheus-2.3.2.linux-amd64.tar.gz -C /usr/local/ cd /usr/local/ && mv prometheus-2.3.2.linux-amd64/ prometheus 验证 [root local]# cd prometheus/ [root prometheus]# ./prometheus --version prometheus, version 2.3.2 (branch: HEAD, revision: 71af5e29e815795e9dd14742ee7725682fa14b7b) build user: root@5258e0bd9cc1 build date: 20180712-14:02:52 go version: go1.10.3

备份配置文件并配置

cp prometheus.yml prometheus.yml-bak

my global config

global:

scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute. evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.

scrape_timeout is set to the global default (10s).

Alertmanager configuration

alerting:

alertmanagers:

• static_configs:
  • targets:

    - alertmanager:9093

Load rules once and periodically evaluate them according to the global 'evaluation_interval'.

rule_files:

- "first_rules.yml"

- "second_rules.yml"

A scrape configuration containing exactly one endpoint to scrape:

Here it's Prometheus itself.

scrape_configs:

The job name is added as a label job=<job_name> to any timeseries scraped from this config.

• job_name: 'prometheus'

  metrics_path defaults to '/metrics'

  scheme defaults to 'http'.

  static_configs:

  • targets: ['192.168.244.128:9090','192.168.244.129:8080']

添加需要监控的服务器IP和端口

启动（后台启动）

./prometheus --config.file=prometheus.yml & 然后我们可以访问 通过点击下拉栏选取指标，点击”Excute” 我们能够看到Prometheus的性能指标。 点击”status”可以查看相关状态。

4.node_exporter安装

wget 解压并安装 tar xf node_exporter-0.16.0.linux-amd64.tar.gz C /usr/local/ cd /usr/local/ && mv mv node_exporter-0.16.0 node_exporter cd node_exporter/ && ./node_exporter &

返回一大堆指标

5.grafana安装

wget sudo yum localinstall grafana-5.2.3-1.x86_64.rpm 服务端图像呈现组件安装 yum install fontconfig freetype* urw-fonts -y 开启系统默认启动 systemctl enable grafana-server 启动服务 systemctl start grafana-server 查看服务是否正常启动 systemctl status grafana-server [root ~]# systemctl status grafana-server ● grafana-server.service - Grafana instance Loaded: loaded (/usr/lib/systemd/system/grafana-server.service; enabled; vendor preset: disabled) Active: active (running) since 四 2018-08-30 16:18:55 CST; 3h 23min ago Docs: Main PID: 10535 (grafana-server) CGroup: /system.slice/grafana-server.service └─10535 /usr/sbin/grafana-server --config=/etc/grafana/grafana.ini --pidfile=/var/run/grafana/grafana-server.pid ... 访问grafana, 默认用户名密码:admin/admin

客户端（被监控）

6.安装cAdvisor 来收集容器信息 所有节点运行以下命令来安装cAdvisor docker run \ --volume=/:/rootfs:ro \ --volume=/var/run:/var/run:rw \ --volume=/sys:/sys:ro \ --volume=/var/lib/docker/:/var/lib/docker:ro \ --publish=8080:8080 \ --detach=true \ --name=cadvisor \ --net=host \ -v "/etc/localtime:/etc/localtime" \ google/cadvisor:latest

为grafana添加Prometheus数据源
