A lightweight Elixir wrapper for exometer that simplifies metric definition and automatic subscription to reporters.
Elixometer is a lightweight Elixir wrapper around the exometer Erlang library that simplifies metric instrumentation. It automatically subscribes defined metrics to the configured reporter based on the environment, reducing boilerplate and configuration overhead. The library supports various metric types including timers, histograms, gauges, counters, and spirals with straightforward update functions.
Elixir developers building applications that require performance monitoring and metric collection, particularly those who want to integrate with existing exometer reporters like StatsD or OpenTSDB without dealing with exometer's complexity.
Developers choose Elixometer because it abstracts the complexities of exometer with automatic metric subscription, minimal configuration, and developer-friendly features like function timing annotations. It provides overload protection through pobox integration and supports custom formatters and bulk reporting for efficient metric handling.

Reduces boilerplate by automatically subscribing metrics to configured reporters based on the environment, as shown in the configuration examples that prepend prefixes and environment names.
Simplifies metric updates with straightforward functions for counters, timers, etc., and supports @timed annotations for automatic key generation in function timing.
Allows custom formatters for metric naming and bulk reporting for efficient handling, enabling tailored integration with various reporters like StatsD or OpenTSDB.
Integrates with pobox to buffer messages and prevent system overload, with configurable max_messages limits to manage high metric volumes safely.
Relies on exometer, which has poor and difficult-to-find documentation for custom reporters, as admitted in the README, adding setup complexity.
Requires coordinating multiple config files for exometer and elixometer, including reporter settings and subscription options, which can be error-prone.
Tied to exometer's supported metric types and reporters, which may lack modern features or active development compared to newer libraries like Prometheus clients.
