Docker容器Telegraf+InfluxDB+Grafana实例实现Linux系统监控
Docker环境中实现Telegraf+InfluxDB+Grafana实现Linux系统监控功能。Telegraf是一个收集指标并将其写入InfluxDB或其他输出的代理。
目录
Linux监控环境安装
获取Telegraf镜像
运行InfluxDB容器
运行Telegraf容器
运行Grafana容器
Grafana管理和配置
配置InfluxDB数据源
配置Telegraf InfluxDB 面板
JSON Model数据配置复用
Linux监控环境安装
Docker安装这里不做讲解。
获取Telegraf镜像
https://hub.docker.com/_/telegraf
获取镜像可以不用单独操作，运行容器时如本地没有此镜像会在运行容器时自动下载。
$ docker pull telegraf运行InfluxDB容器
$ docker run -d --name influxdb -p 8083:8083 -p 8086:8086 influxdbInfluxDB 数据源地址：http://${host|container_ip}:8086/
运行Telegraf容器
$ docker run --net=container:influxdb telegraf注：需要先运行InfluxDB容器，之后会自动创建InfluxDB 示例数据库telegraf。
运行Grafana容器
https://hub.docker.com/r/grafana/grafana
$ docker run -d --name=grafana -p 3000:3000 grafana/grafanaGrafana管理端地址是:http://${host|container_ip}:3000/ 用户名密码默认均为：admin
Grafana管理和配置
打开Grafana的管理界面输入用户密码，对后续进行操作。
配置InfluxDB数据源
左侧配置管理：
设置选择数据库类型为InfluxDB并设置数据源和密码：
可以在保存的时候进行连接可用性验证：
配置完成后配置主界面会有这样一个实例:
配置Telegraf InfluxDB 面板
找到左侧添加的Dashboard:
然后通过Add Query来添加查询面板：
以CPU为例：
展示一个Telegraf的系统监控所有指标面板：
JSON Model数据配置复用
Telegraf系统监控JSON（新容器复制粘贴JSON可以快速实现面板重建）：
