生成配置文件

可执行文件在/usr/bin/telegraf,配置文件在/etc/telegraf目录下，也可直接配置生成

• 查看帮助

telegraf --help

• 生成配置文件

telegraf config > telegraf-mysql.conf   #比如在当前目录下生成mysql相关的配置文件

• 生成指定输入和输出插件的配置文件

telegraf --input-filter <pluginname>[:<pluginname>] --output-filter <outputname>[:<outputname>] config > telegraf.conf

eg:生成带CPU、memory、disk diskio、net和influxdb插件带配置文件telegraf.conf,指定输出到influxdb和opentsdb

telegraf --input-filter cpu:mem:disk:diskio:net --output-filter influxdb:opentsdb config > telegraf.conf

　也可使用默认到配置文件

telegraf --input-filter cpu:mem:http_listener --output-filter influxdb config 

• telegraf支持读取多个配置文件，可将多个配置文件放置在/etc/telegraf/telegraf.d目录下

测试配置是否成功

示例

# 测试 /etc/telegraf/telegraf.conf 配置文件中输入 cpu 配置是否正确
telegraf  -config /etc/telegraf/telegraf.conf -input-filter cpu -test
# 测试 /etc/telegraf/telegraf.conf 输出 influxdb 配置是否正确
telegraf  -config /etc/telegraf/telegraf.conf -output-filter influxdb -test
# 测试 /etc/telegraf/telegraf.d/mysql.conf 输入 cpu 和 输出 influxdb 配置是否正确
telegraf  -config /etc/telegraf/telegraf.d/mysql.conf -input-filter cpu  -output-filter influxdb -test
配置正确的话，会输出当前时间戳的配置指标和值；

配置错误的话，会显示错误信息；
