HealthChecks
============
``metrics-clojure-health`` will allow you to define and run healthcheck.
Install
-------
``metrics-clojure-health`` is provided as a separate package from ``metrics.core``.
To install add the following to your ``project.clj``:
.. parsed-literal::
[metrics-clojure-health "|release|"]
Example
-------
An example using the default HealthCheckRegistry, (which is different
from the default-registry).::
(require '[metrics.health.core :as health])
(defhealthcheck "second-check" (fn [] (let [now (.getSeconds (java.util.Date.))]
(if (< now 30)
(health/healthy "%d is less than 30!" now)
(health/unhealthy "%d is more than 30!" now)))))
(health/check second-check)
#_ => #<Result Result{isHealthy=true, message=3 is less than 30!}>
(health/check-all)
#_ => {:healthy [#<UnmodifiableEntry foo=Result{isHealthy=true, message=6 is less than 30!}>]}
