Metrics

Server middleware to record metrics for the http4s server.

This middleware will record: - Number of active requests - Time duration to send the response headers - Time duration to send the whole response body - Time duration of errors and other abnormal terminations

This middleware can be extended to support any metrics ecosystem by implementing the MetricsOps type
