Intro

A client library for the Gelf protocol with a fully compliant and correct implementation (chunking works).

It has an appender implemented for timbre, nothing prevents it from being used in any other logging framework.

Usage

  [com.narkisr/gelfino-client "0.8.1"]

Raw client use:

(connect)

(send-> "0.0.0.0" {:short_message "i am a unicorn" :message "i am a unicorn" :level 4})

; A chunked message
(send-> "localhost" 
  {:short_message "i am a unicorn" :message (apply str (take 400000 (repeat "I am a unicorn")))})

Using timbre appender:

(use '[gelfino.timbre :only (gelf-appender)])
(use '[taoensso.timbre :only (set-config! set-level!)])

(set-config! [:appenders :gelf] gelf-appender)
(set-config! [:shared-appender-config :gelf] {:host "graylog2/kibana"})

See api docs.

Transaction id (tid)

Gelfino client has the ability to set a logicl transction accross spanning components and threads:

  (set-tid id 
    ; all logs with current thread will have :_tid id value    
   )

All that is required in order to see the linear log flow of such a transaction is add _tid field to your search query.
