Functions to build clj-http middlewares that report timing metrics.
Functions to build clj-http middlewares that report timing metrics.
build-wrap-metricsclj
(build-wrap-metrics title-fn)(build-wrap-metrics registry title-fn)Creates a clj-http middleware that reports timing metrics.
NOTE: The middleware produced currently only supports synchronous operations.
title-fn is a function that accepts a request and returns a title. The title
may be a dot-delimited string (e.g., a.b.c) or a sequence of strings (e.g.,
["a" "b" "c"].
registry is an optional parameter that is a
com.codahale.metrics.MetricRegistry. If one is not provided, the
metrics.core/default-registry will be used.
Creates a clj-http middleware that reports timing metrics. NOTE: The middleware produced currently only supports synchronous operations. `title-fn` is a function that accepts a request and returns a title. The title may be a dot-delimited string (e.g., `a.b.c`) or a sequence of strings (e.g., `["a" "b" "c"]`. `registry` is an optional parameter that is a `com.codahale.metrics.MetricRegistry`. If one is not provided, the `metrics.core/default-registry` will be used.
prefixed-title-fnclj
(prefixed-title-fn title-fn prefix)Creates a new title-fn that applies the prefix to the output of title-fn.
Creates a new title-fn that applies the prefix to the output of title-fn.
title-from-urlclj
(title-from-url {:keys [url]})Generates a metric title in sequential form from the provided URL.
This function is designed to operate on a clj-http request and can be used as
a title-fn for build-wrap-metrics.
The produced title will be in the following form contain the reversed hostname
followed by the path, in sequential form. For example, the URL
http://subdomain.example.com/some/path would be transformed into the
following title:
["com" "example" "subdomain" "some" "path"]
Generates a metric title in sequential form from the provided URL. This function is designed to operate on a clj-http request and can be used as a `title-fn` for [[build-wrap-metrics]]. The produced title will be in the following form contain the reversed hostname followed by the path, in sequential form. For example, the URL `http://subdomain.example.com/some/path` would be transformed into the following title: `["com" "example" "subdomain" "some" "path"]`
