Clojure wrapper for New Relic

Add this to your Leiningen project.clj :dependencies:

[yleisradio/new-reliquary "1.0.0"]

Jar is available in Clojars.

Basic NewRelic transaction tracing utilities located in new-reliquary.core

(defn with-newrelic-transaction
  ([category transaction-name custom-params callback] ...)
  ([category transaction-name callback]               ...)
  ([callback]                                         ...))

Creates a transaction with optional transaction name and custom params. If transaction name is not passed, then set-transaction-name should be used inside the transaction.

Sets name to the transaction. Must be used if transaction is created with with-newrelic-transaction callback. See https://newrelic.github.io/java-agent-api/javadoc/com/newrelic/api/agent/NewRelic.html#setTransactionName(java.lang.String,%20java.lang.String)

See https://newrelic.github.io/java-agent-api/javadoc/com/newrelic/api/agent/NewRelic.html#noticeError(java.lang.String)

See https://newrelic.github.io/java-agent-api/javadoc/com/newrelic/api/agent/NewRelic.html#ignoreTransaction()

Adds new custom parameter to the transaction. Must be called inside the transaction. See: https://newrelic.github.io/java-agent-api/javadoc/com/newrelic/api/agent/NewRelic.html#addCustomParameter(java.lang.String,%20java.lang.String)

(:require [new-reliquary.core :as newrelic])

(defn update-facebook-likes [] ...)

(newrelic/with-newrelic-transaction
    "My custom category"
    "Facebook data updating"
    {:user "jk" :huge-clojure-fan true}
    update-facebook-likes)
    
(newrelic/with-newrelic-transaction 
  (fn [] (newrelic/set-transaction-name "backend" "poller") ...)

Middleware to start NewRelic web transaction. Located in new-reliquary.ring

If you want to add query parameters as new relic custom params, make sure that request contains hash map :query-params (not in the default ring setup). This can be achieved easily by using ring.middleware.params/wrap-params.

(ns new-reliquary-example.main
  (:require [new-reliquary.ring :refer [wrap-newrelic-transaction]]
            [ring.middleware.params :refer [wrap-params]]))

(defn request-handler [request] {:body "Hello world"})
(def app (-> request-handler
            (wrap-newrelic-transaction)
            (wrap-params)))
