prometheus
An Erlang client library for the Prometheus monitoring system, providing metrics collection and exposition.
What is prometheus?
Prometheus.erl is a native Erlang client library for the Prometheus.io monitoring system and time series database. It enables Erlang and Elixir applications to expose internal metrics in the Prometheus format, facilitating observability and performance monitoring. The library supports all core Prometheus metric types and integrates with various Erlang/OTP components and popular web frameworks.
Erlang and Elixir developers building applications that require observability and performance monitoring, particularly those already using or planning to use the Prometheus ecosystem for metrics collection and visualization.
Developers choose Prometheus.erl because it provides a clean, idiomatic Erlang API that follows Prometheus instrumentation best practices while maintaining full compatibility with the broader Prometheus ecosystem. It offers built-in collectors for the Erlang VM and ready-to-use integrations with popular frameworks like Cowboy, Phoenix, and Ecto, reducing the effort needed to instrument applications.
