Does Grafana update fast enough for visualizing data from sensors on robots? (in particular for tracking positional information or response information if tuning/monitoring PIDs etc.)?

Director of UX here. This year we rewrote a lot of the data flow plumbing in grafana to allow streaming with the very goal to enable sensor and other high frequency use cases. More to come soon

How much of those improvements is in current versions of Grafana? I've tried building some dashboards in Chronograf for some data I work with, but there's a lot of sensors that update very quickly so the graphs basically killed the browser tab. If Grafana is better at handling that sort of use case I'll definitely check it out.

Very cool, anywhere I can read up more on this?

Grafana was pretty fast, but the total system latency can add up to about 1 second or so (wifi at least, cellular is longer).

We did not use grafana for debugging instantaneous, fast events, but it was fantastic for things like monitoring temperature, current modes, and running statistics.
