duckula.monitoring

A fully functioning monitoring component for Duckula.

• Reports metrics to Statsd via Stature
• Reports exceptions to Rollbar via Caliban

Only useful if you're using Duckula :wink:

Options

• name: (optional) name of the monitoring stack, usually will be the name of your service, used only for lifecylce logs
• exclude-pattern: (optional) a Regex to filter out metrics that you don't want to report on, e.g health-check routes, it will also switch logs to DEBUG only level. Note that exceptions thrown will always be tracked and reported!

Usage

(def system
  {;; see Caliban docs for more info
   :exception-tracker (caliban.tracker/create {:token "rollbar-token"
                                               :environment "production"})
   ;; see Stature docs for more info
   :statsd (stature.metrics/create {:host "localhost" :port 8125 :prefix "duckula-test"})
   ;; put it all together
   :monitoring (component/using
                (duckula.monitoring/create {:name "my-api" :exclude-pattern #".+health-check.+"})
                [:statsd :exception-tracker])
   ;; sets up the web request handler
  ;; ring-compatible web server component must be provided by you
  :ring-handler (component/using
                  (duckula.handler/create handler-config)
                  [:monitoring ; defined above
                   :db :publisher :elasticsearch])
   ;; ----
   ;; rest of your dependencies and the component system
   :publisher (bunnicula.publisher/create rmq-config)
   :db (...)
