InfluxDB : Install Telegraf2022/11/16 |
|
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 from the InfluxDB official repository. |
|
[root@dlp ~]# dnf -y install telegraf
|
| [2] | Configure Telegraf. As an example, configure it to get CPU related metrics on the system and send them to InfluxDB. |
