Docker Compose 部署监控系统 Prometheus + Grafana + Node Exporter + Cadvisor
原创Docker Compose 部署监控系统 Prometheus + Grafana + Node Exporter + Cadvisor
原创
前言
Prometheus + Grafana + Node Exporter + Cadvisor是一款开源的服务器系统状态监控平台系统,用于管理和存储各服务器的实时信息数据,方便监控和排查服务器故障.博主经过一段时间的安装,配置,测试也基本满足了个人以及中小企业团队对于日志管理的需求.整合了相对详细的部署和配置教程分享给大家.
本教程使用docker-compose整合部署,参考 stefanprodan/dockprom.
项目流程
服务端:部署Prometheus + Grafana到主监控服务器
客户端:部署Node Exporter + Cadvisor到需要被监控的服务器
常规流程
客户端通过Node Exporter采集系统状态信息,Cadvisor采集docker容器信息,并开放端口,由服务端Prometheus进行抓取,并由Grafana提供前端展示.
服务器部署 Prometheus + Grafana
拉取代码
git clone -b master https://github.com/stefanprodan/dockprom prom创建 cadday 密码
docker run --rm caddy caddy hash-password --plaintext 'youtpasswd'
# 获取 hash 密码
JDJhJDE0JHJmeldKeDB0NjJnY0tjQk5wZXVYaC50QjdSbi9aVlVZeFYyV012UkI2Ydocker-compose.yml
volumes:
创建数据目录
cd prom
mkdir prometheus_data grafana_data
# 创建数据目录修改docker-compose.yml中顶级卷配置到指定目录用于存储数据
volumes:
prometheus_data:
driver: local
driver_opts:
type: 'none'
o: 'bind'
device: '/root/prom/prometheus_data'
grafana_data:
driver: local
driver_opts:
type: 'none'
o: 'bind'
device: '/root/prom/grafana_data'配置 grafana 密码
yourpasswd修改为你的grafana登陆密码
environment:
- GF_SECURITY_ADMIN_USER=${ADMIN_USER:-admin}
- GF_SECURITY_ADMIN_PASSWORD=${ADMIN_PASSWORD:-yourpasswd}
- GF_USERS_ALLOW_SIGN_UP=false配置 caddy 密码
修改上文生成的caddy hash密码
environment:
- ADMIN_USER=${ADMIN_USER:-admin}
- ADMIN_PASSWORD=${ADMIN_PASSWORD:-admin}
- ADMIN_PASSWORD_HASH=${ADMIN_PASSWORD_HASH:-JDJhJDE0JHJmeldKeDB0NjJnY0tjQk5wZXVYaC50QjdSbi9aVlVZeFYyV012UkI2Y配置 prometheus.yml
使用 file_sd_configs 配置独立配置文件路径,方便随时修改配置而不需要重启容器,并且方便批量分类管理.
创建独立配置目录
在./prometheus创建jobs目录,创建独立配置文件:
- nodeexporter.yml
- cadvisor.yml
- prometheus.yml
- pushgateway.yml
独立配置文件
参考示例./prometheus/jobs/nodeexporter.yml
- targets:
- "127.127.127.127:9100"
labels:
hostname: Server
- targets:
- "127.127.127.128:9100"
labels:
hostname: Server1
- targets:
- "127.127.127.129:9100"
labels:
hostname: Server2参考示例./prometheus/jobs/cadvisor.yml
- targets:
- "127.127.127.127:8080"
labels:
hostname: Server
- targets:
- "127.127.127.128:8080"
labels:
hostname: Server1
- targets:
- "127.127.127.129:8080"
labels:
hostname: Server2配置 prometheus.yml
参考修改独立配置文件路径./prometheus/prometheus.yml
scrape_configs:
- job_name: 'nodeexporter'
file_sd_configs:
- files:
- "/etc/prometheus/jobs/nodeexporter.yml"
refresh_interval: 5s
- job_name: 'cadvisor'
file_sd_configs:
- files:
- "/etc/prometheus/jobs/cadvisor.yml"
refresh_interval: 5s
- job_name: 'prometheus'
file_sd_configs:
- files:
- "/etc/prometheus/jobs/prometheus.yml"
refresh_interval: 5s
- job_name: 'pushgateway'
file_sd_configs:
- files:
- "/etc/prometheus/jobs/pushgateway.yml"
refresh_interval: 5s客户端配置
docker-compose.yml
防火墙需开放以下相关端口,注意 nodeexporter 使用 network_mode: host 否则流量监控可能不准.
version: '3.2'
services:
nodeexporter:
image: prom/node-exporter:v1.1.2
container_name: nodeexporter
volumes:
- /proc:/host/proc:ro
- /sys:/host/sys:ro
- /:/rootfs:ro
# ports:
# - 9100:9100
environment:
TZ: Asia/Shanghai
command:
- '--path.procfs=/host/proc'
- '--path.rootfs=/rootfs'
- '--path.sysfs=/host/sys'
- '--collector.filesystem.ignored-mount-points=^/(sys|proc|dev|host|etc)($$|/)'
