// First, in more complex programs, global state is often quite problematic.
// That's the reason why the metrics constructors in the prometheus package do
// not interact with the global prometheus.DefaultRegisterer on their own. You
// are free to use the Register or MustRegister functions to register them with
// the global prometheus.DefaultRegisterer, but you could as well choose a local
// Registerer (usually created with prometheus.NewRegistry, but there are other
// scenarios, e.g. testing).
//
// The second issue is that registration may fail, e.g. if a metric inconsistent
// with the newly to be registered one is already registered. But how to signal
// and handle a panic in the automatic registration with the default registry?
// The only way is panicking. While panicking on invalid input provided by the
// programmer is certainly fine, things are a bit more subtle in this case: You
// might just add another package to the program, and that package (in its init
// function) happens to register a metric with the same name as your code. Now,
// all of a sudden, either your code or the code of the newly imported package
// panics, depending on initialization order, without any opportunity to handle
// the case gracefully. Even worse is a scenario where registration happens
// later during the runtime (e.g. upon loading some kind of plugin), where the
// panic could be triggered long after the code has been deployed to
// production. A possibility to panic should be explicitly called out by the
// Must… idiom, cf. prometheus.MustRegister. But adding a separate set of
// constructors in the prometheus package called MustRegisterNewCounterVec or
// similar would be quite unwieldy. Adding an extra MustRegister method to each
// metric, returning the registered metric, would result in nice code for those
// using the method, but would pollute every single metric interface for
// everybody avoiding the global registry.
//
// To address both issues, the problematic auto-registering and possibly
// panicking constructors are all in this package with a clear warning
// ahead. And whoever cares about avoiding global state and possibly panicking
// function calls can simply ignore the existence of the promauto package
// altogether.
//
// A final note: There is a similar case in the net/http package of the standard
// library. It has DefaultServeMux as a global instance of ServeMux, and the
// Handle function acts on it, panicking if a handler for the same pattern has
// already been registered. However, one might argue that the whole HTTP routing
// is usually set up closely together in the same package or file, while
// Prometheus metrics tend to be spread widely over the codebase, increasing the
// chance of surprising registration failures. Furthermore, the use of global
// state in net/http has been criticized widely, and some avoid it altogether.

# Prometheus Ruby client model
Data model artifacts for the [Prometheus Ruby client][1].
## Installation
gem install prometheus-client-model
## Usage
Build the artifacts from the protobuf specification:
make build
While this Gem's main purpose is to define the Prometheus data types for the
[client][1], it's possible to use it without the client to decode a stream of
delimited protobuf messages:
```ruby
require 'open-uri'
require 'prometheus/client/model'
CONTENT_TYPE = 'application/vnd.google.protobuf; proto=io.prometheus.client.MetricFamily; encoding=delimited'
stream = open('http://localhost:9090/metrics', 'Accept' => CONTENT_TYPE).read
while family = Prometheus::Client::MetricFamily.read_delimited(stream)
puts family
end
```
