Prometheus monitoring for shiny applications, plumber APIs, and other R web services.
I have put this package together in order to 1) grasp a better understanding of Prometheus metrics and 2) have some direct control over the source code of software I deploy for clients. I have written and re-written this three times before discovering openmetrics, an R package that provides the same functionalities. I have taken much inspiration from it.
Prometheus is the titan god of fire.
There are other packages out there that will let you serve Prometheus metrics.
