Prometheus Client HTTP Endpoint

The PromClient exposes an HTTP endpoint, usually at <HOSTNAME>:3001/metrics. By navigating to this URL, you can view and retrieve the metrics data that PromClient is collecting and processing. This data is formatted for Prometheus, but it's also human-readable to a degree, allowing for direct inspection. This endpoint is key for integrating with Prometheus, which will regularly scrape this data for monitoring and analysis.
