Create A Dashboard For Linux System Metrics
Video Lecture
Description
Now that we have a System dashboard visible in InfluxDB, we can also re-produce this same dashboard in Grafana.
In this video, I demonstrate the process of doing that.
The full dashboard json that you can import into Grafana is below.

Grafana 9 and Ubuntu 22.04 Notes
There are no considerable differences to be aware of as shown and discussed in the video.
Telegraf v1.24.1
I have tested Telegraf v1.24.1. There are no significant differences to be aware of other than some presentation differences in the InfluxDB UI.
