clj-http-metrics

A clj-http middleware that reports timing metrics.

NOTE: The middleware currently only supports synchronous operations.

Usage

The following example uses the default Codahale metric registry and specifies that the metric titles should be based upon the request URL and apply a prefix.

The metric title for the URL http://subdomain.example.com/some/path is my-prefix.com.example.subdomain.some.path in the following setup. Timing metrics will appear under that title.

(require '[clj-http.client :as client])
(require '[clj-http.middleware.metrics :as m])

(def wrap-metrics
  (m/build-wrap-metrics (m/prefixed-title-fn m/title-from-url "my-prefix"))

(client/with-additional-middleware [#'wrap-metrics]
  (client/get ...))
