Azure Functions (Python) の HTTP トリガーを New Relic Agent で監視する方法

Last updated at 2026-07-09Posted at 2026-07-09

概要

Azure Functions における Python の HTTP トリガー処理を、New Relic Agent 経由で New Relic 上で監視する方法を紹介します。

New Relic の下記のドキュメントにて紹介されている手順を参考にしています。

Linux instrumentation | New Relic Documentation

手順

1. New Relic にて接続情報を取得

`NEW_RELIC_LICENSE_KEY`環境変数に設定するキーを取得

New Relic のページにアクセスし、右上の自分のアカウント -> API Keysを選択します。

Create a keyを選択します。

Key typeにIngest - Licenseを選択後、Nameに任意の名称を入力し、Create a keyを選択します。

表示されたキーの値を控えます。

2. Azure Functions にデプロイ

ローカル環境にて Azure Functions の開発環境の準備

requirements.txt の準備

azure-functions
newrelic

関数の処理のコードを function_app.py に記述

New Relic の初期化と登録を実施しています。

処理内容は現在時刻を表示するシンプルなものです。

コードの詳細はこちらを選択

import os
import logging
import time
from datetime import datetime, timezone

import azure.functions as func
import newrelic.agent

# New Relic エージェント初期化
newrelic.agent.initialize()

# New Relic アプリケーションを登録
APP_NAME = os.environ.get("NEW_RELIC_APP_NAME")
NR_APP = newrelic.agent.register_application(name=APP_NAME)

# Azure Functions アプリケーションインスタンス
app = func.FunctionApp()

# トリガータイプに応じた共通処理を実行する関数
def run_test(trigger_type: str) -> str:
    # 現在時刻（UTC）を ISO 8601 形式で取得
    now_utc = datetime.now(timezone.utc).isoformat()

    # トリガー開始をログに記録
    logging.info("%s trigger started. current_time_utc=%s", trigger_type, now_utc)

    # New Relic にトリガータイプをカスタム属性として送信
    newrelic.agent.add_custom_attribute("trigger.type", trigger_type)

    # 処理をシミュレートするための遅延 (2秒)
    time.sleep(2)

    # 完了時刻（UTC）を ISO 8601 形式で取得
    finished_at = datetime.now(timezone.utc).isoformat()
    # トリガー完了をログに記録
    logging.info("%s trigger finished. current_time_utc=%s", trigger_type, finished_at)

    return finished_at


# HTTP トリガー: New Relic 動作確認用エンドポイント
@app.function_name(name="http_newrelic_test")
@app.route(
    route="newrelic-test",
    methods=["GET"],
    auth_level=func.AuthLevel.FUNCTION,
)
def http_newrelic_test(req: func.HttpRequest) -> func.HttpResponse:
    # 共通処理を実行し、完了時刻を取得
    finished_at = run_test("http")

    # レスポンスを返す
    return func.HttpResponse(
        body=f"OK. finished_at_utc={finished_at}",
        status_code=200,
    )

Azure Function App に環境変数を設定

下記の環境変数を追加します。

NEW_RELIC_LICENSE_KEY: New Relic から取得した API キーをセット
NEW_RELIC_APP_NAME: New Relic 上で表示する Azure Functions アプリ名

Azure Function App にコードをデプロイ

3. Azure Function App の関数の実行と計測

Azure ポータルにてデプロイした関数を表示

デプロイしたhttp_newrelic_test関数を選択します。

テスト/実行を選択します。

HTTP メソッドにてGETを選択し、実行を選択します。

正常終了することを確認します。

New Relic にてデータを確認

New Relic にて APM & Services -> NEW_RELIC_APP_NAME環境変数に指定した名称を選択します。

データが連携されていることを確認します。

Transactions にて実行した関数であるhttp_newrelic_testを確認できます。
