InfluxDB : Install Telegraf2023/07/06 |
|
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:~# curl -fsSL https://repos.influxdata.com/influxdata-archive_compat.key -o /etc/apt/keyrings/influxdata-archive_compat.key root@dlp:~# echo "deb [signed-by=/etc/apt/keyrings/influxdata-archive_compat.key] https://repos.influxdata.com/debian stable main" | tee /etc/apt/sources.list.d/influxdata.list root@dlp:~# apt update 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. |
