Generating RRD-Style graphs with Prometheus data

[Andrew K]

Hello,

I'm looking at generating graphs similar to mbix here: http://www.mbix.ca/statistics/

These images must be static (jpg/png) for day, week, month, year. They also must have "Current", "Average", and "Maximum" points from the graph.

I know something like Grafana can be used to create graphs, but I really want to keep this as simple as possible and running Grafana seems a bit overkill for what I want.

I've seen that promplot (https://github.com/qvl/promplot) can do almost what I want, but it seems pretty rudimentary and hasn't been maintained for nearly 3 years.

Does anyone know a good method/tool/library to accomplish this?

Thanks!
