metrics

Abstracts over ten different collectors including StatsD, Prometheus, and InfluxDB, allowing developers to switch backends without code changes, as highlighted in the README's supported backends list.

Provides consistent methods like increment(), decrement(), timing(), and measure() across all backends, making instrumentation straightforward and reducing learning curve.

Ships with a ready-to-use Symfony Bundle for easy configuration and service injection, demonstrated in the README with YAML configuration examples.

Includes a flush() method for backends that aggregate metrics, enabling efficient batch sending to reduce network overhead, as noted in the API section.
