The author talks about Graphite and Prometheus as instrumentation systems but they're for collecting data. What do people recommend as a linkable library for collecting metrics in the service process? (before it is collected). A quick google gave me 'go-metrics' and 'dropwizard metrics' but the code I'm working on will require linking with a native C library.

The author is a Go developer; if you are too, a good starting point is to use expvar and then whatever tool your collector provides for collecting expvars. Besides being in the standard library, there's the advantage of there being lots of tools that speak expvar.

Thanks for that. 'expvar' looks like a great hidden gem for go development. Unfortunately most of our services aren't written in Go so we might have to write our own if there isn't a handy library we could write bindings for.
