You should put this middleware at the top of your middleware stack to get the most visibility.

The middleware provides the following dogstatsd metrics:

• http.1xx - counter of 1xx responses
• http.2xx - counter of 2xx responses
• http.3xx - counter of 3xx responses
• http.4xx - counter of 4xx responses
• http.5xx - counter of 5xx responses
• http.count - counter for total requests
• http.exception - counter for exceptions raised
• http.duration - histogram of request duration

Options is a map of:

• loggable? A predicate that filters a request from being measured. By default, this is (component healthcheck-request?)
• sample-rate A float between 0 and 1. Sets the rate of requests to sample.
• tags vector of additional tags to add to the metrics
