InfluxDB : Install Telegraf2022/10/28 |
|
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/v1.24/plugins/
|
|
| [1] | Install Telegraf. |
|
root@dlp:~# apt -y install telegraf
|
| [2] | Configure Telegraf. As an example, configure it to get CPU related metrics on the system and send them to InfluxDB. |
