reporter: event, errors and metric reporting component

The reporter component makes it easy to wire-in support for the following in your components:

• Event reporting to riemann
• Metric reporting with metrics with support for JMX, Riemann and Console output
• Error captures to sentry
• Expose prometheus metrics via HTTP
• Send metrics to PushGateway

Reporter provides a component in order to be declared as a dependency in other components.

Configuring

Reporter exposes a schema if you wish to validate config, simply pull-in schema.core and either use spootnik.reporter/config-schema as an argument to schema.core/validate or use the handy function spootnik.reporter/config-validator.

Using

Start the component with

(spootnik.reporter/initialize! reporter-config)

Once started, the spootnik.reporter/reporter variable will contain your component. You can then use the following signatures:

(defprotocol RiemannSink
  (send! [this e]))

(defprotocol SentrySink
  (capture! [this e]))

(defprotocol PushGatewaySink
  (gauge! [this e])
  (counter! [this e]))

(defprotocol MetricHolder
  (instrument! [this prefix])
  (build! [this type alias] [this type alias f])
  (inc! [this alias] [this alias v])
  (dec! [this alias] [this alias v])
  (mark! [this alias])
  (update! [this alias v])
  (time-fn! [this alias f])
  (start! [this alias])
  (stop! [this alias]))

The spootnik.reporter namespace contains helper functions to interact with the reporter instance.
