Zipkin publisher

In order to use the library add the dependency to your project.clj

;; Leiningen project
[com.brunobonacci/mulog-zipkin "x.x.x"]

;; deps.edn format
{:deps { com.brunobonacci/mulog-zipkin {:mvn/version "x.x.x"}}}

Current version:

The events must be serializeable in JSON format (see How to JSON encode custom Java classes for more info.)

The available configuration options:

{:type :zipkin

 ;; Zipkin endpoint (REQUIRED)
 :url  "http://localhost:9411/"


 ;; the maximum number of events which can be sent in a single
 ;; batch request to Zipkin
 :max-items     5000

 ;; Interval in milliseconds between publish requests.
 ;; μ/log will try to send the records to Zipkin
 ;; with the interval specified.
 :publish-delay 5000

 ;; a function to apply to the sequence of events before publishing.
 ;; This transformation function can be used to filter, tranform,
 ;; anonymise events before they are published to a external system.
 ;; by defatult there is no transformation.  (since v0.1.8)
 :transform identity
 }

How to use it:

(μ/start-publisher!
  {:type :zipkin
   :url  "http://localhost:9411/"})

Here is an example of how the traces look like:

NOTE: Zipkin requires an application name for the traces, use set-global-context to define one, like:

  ;; set global context
  (μ/set-global-context!
    {:app-name "my-app", :version "0.1.0", :env "local"})

see example here.
