Hello, Prometheus!

This is a very basic usage example of the library, and probably useless, but includes everything you need to know for getting started.

TPrometheusRegistry maintains a store of values in memory, and coordinates everything, from exposing the storage to freeing memory when needed.

You can create instances of TPrometheusCounter, TPrometheusGauge and TPrometheusHistogram directly from the Registry.

How to build this example

A working installation of Free Pascal compiler, 3.0.0 or newer, is the only requirement.

For convenience, there is a GNU Make’s Makefile that automates the building:

# Compile the example
$ make

# Run it
$ ./helloworld

Please take a look to the Makefile to see how you can link your program to this library.
