How do I find a telegraf plugin for a dashboard?

I’m not sure if I am in the correct area so apologies if I am not.

I have been learning about Grafana, InfluxDB and Telegraf. I’ve been watching some videos and setting up Telegraf to collect data which then pushes it to Influx and then i can see it all in my Grafana graphs

My question is where do I find the “telegraf” plugin configuration code for a Graph when its not listed?

For example, say I wanted to implement this dashboard;

I know how to import the JSON file into Grafana, but how do I work out what the telegraf conf is to put on the machine that will be used to collect/output the data?

Thanks!
