InfluxDB : Install Telegraf2024/08/26 |
|
Install Telegraf which can collect or send various metrics. Telegraf supports many Input /Output plugins, refer to the official site below. ⇒ https://docs.influxdata.com/telegraf/v1.27/plugins/ |
|
| [1] | Install Telegraf. |
|
root@dlp:~ # pkg install -y telegraf
|
| [2] | Configure Telegraf. As an example, configure it to get CPU related metrics on the system and send them to InfluxDB. |
