物理机上运行

软件说明

  • 操作系统：CentOS Linux release 7.9.2009 (Core)
  • telegraf：telegraf-1.23.3_linux_amd64.tar.gz

使用说明

解压 telegraf-1.23.3_linux_amd64.tar.gz

tar zxvf telegraf-1.23.3_linux_amd64.tar.gz

测试模式启动执行

/usr/bin/telegraf --config etc/telegraf/telegraf.conf --test --input-filter cpu:mem

执行以指令可以采集到 cpu 指标和内存

输出到 influxdb

安装 influxdb 1.8

拉取 influxdb 1.8

docker pull influxdb:1.8

启动 influxdb 1.8

docker run -d -p 8083:8083 -p 8086:8086 --name influxdb-test  influxdb:1.8

使用 influxdb studio 连接 influxdb ，点击地址下载 influxdb studio https://github.com/CymaticLabs/InfluxDBStudio/releases/tag/v0.2.0-beta.1 启动客户端连接。

修改 telegraf 配置

vim etc/telegraf/telegraf.conf

定位到[outputs.influxdb], 把 urls 和 database 参数注释去掉，如下：

启动 telegraf

该指令只收集cpu和内存的相关指标，出现如下内容, 10s为间隔进行采集。

./usr/bin/telegraf --config etc/telegraf/telegraf.conf --input-filter cpu:mem

出现以下日志说明已经进入采集；
