Looks like it should be okay to run from a Pi - seems to be plenty of people talking about it for other IoT projects. The logger I’m using is this one - [RELEASE] InfluxDB Logger. I run mine out of Docker on my NAS which makes it a bit simpler for upgrades & maintenance but has it’s own downsides too (Think you can Docker from Pi as well).
You don’t need to worry about Telegraph (will see it mentioned in some of the other internet posts) to gether the data, the above SA will log straight into the DB.
Grafana was okay but has a bit of a learning curve - I ended up installing Chronograf to help explore the datasets when learning what queries I wanted.
