InfluxDB System Dashboard vs Telegraf InfluxDB Plugin

I thought it would be nice there was a dashboard to see what influxdb is doing, via the _internal database of my InfluxDB instance. I was wondering why this doesn’t come canned. Researching it, I noticed that there is apparently a precanned template that works with a telegraf input plugin (telegraf/plugins/inputs/influxdb at master · influxdata/telegraf · GitHub).

I am curious to understand what the benefit of using Telegraf for this is. Does it provide different data than the _internal database?

There are some internal metrics.
I’ll upload on Grafana a Dashboard that could be used in order to monitor InfluxDB.
On my case helped a lot this plugin.
