OpenTelemetryのzero-code計装を試している〜その5。PHP

tech

zero-code計装シリーズも終盤、PHPでのzero-code計装をやってみる。

kmuto.hatenablog.com kmuto.hatenablog.com kmuto.hatenablog.com kmuto.hatenablog.com

いつものように雑なWebサーバーを立てる。まぁフレームワーク前提だよねということで、ユーザーも多そうなLaravel。大昔にSymphonyしか触わったことがないので初見。

DBはPostgreSQLにしてみる。

apt-get install composer php-pear php8.2-dev php-pgsql

Laravelのプロジェクト作成。デフォルトはsqlite3を使うみたいで、マイグレーション失敗のWARNINGが出た。

composer create-project laravel/laravel hello-world-app
cd hello-world-app

DB設定のために.envファイルを編集する（ローカル用でパスワードなどが雑）。

DB_CONNECTION=pgsql
DB_HOST=127.0.0.1
DB_PORT=5432
DB_DATABASE=laravel_hello_world
DB_USERNAME=laravel
DB_PASSWORD=laravel

PostgreSQLのほうでも対応するDBを準備しておく。

CREATE DATABASE laravel_hello_world;
CREATE USER laravel WITH PASSWORD 'laravel';
GRANT ALL PRIVILEGES ON DATABASE laravel_hello_world TO laravel;
\c laravel_hello_world
GRANT USAGE, CREATE ON SCHEMA public TO laravel;

SCHEMAはこう設定しないとLaravelで作れなかったので。よくはわかっていない。

マイグレーションを実行。

php artisan migrate

ルーティングファイルroutes/web.phpにHello Worldと、例外発生、ステータスコード500返答を仕込む。

<?php

use Illuminate\Support\Facades\Route;

Route::get('/', function () {
    return 'Hello World';
});

Route::get('/error', function () {
    1 / 0;
});

Route::get('/500', function () {
    abort(500, 'Internal Server Error');
});

例外起こすのが連載通してどんどん雑になってきているけど、0除算（静的評価されるとこれダメなんだよねぇ）。

とりあえず起動して期待どおりかテストする。デフォルトは8000ポートで起動する。

php artisan serve

curlから叩いてみると

$ curl http://localhost:8000
Hello World
$ curl http://localhost:8000/error
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

OpenTelemetry Collectorをいつものように用意し、実行しておく。

receivers:
  otlp:
    protocols:
      http:

exporters:
  debug:
    verbosity: detailed

service:
  pipelines:
    metrics:
      receivers: [otlp]
      exporters: [debug]
    logs:
      receivers: [otlp]
      exporters: [debug]
    traces:
      receivers: [otlp]
      exporters: [debug]

PHPのzero-code計装はやや複雑な印象。まずOpenTelemetry Extensionをビルドする必要がある。RPMとAPKはパッケージがあるが、それ以外のOSではpeclかpickleを使う。これもしかしてWindowsだと動かないってやつかも。

とりあえずpeclでやってみる。

sudo pecl install opentelemetry

opentelemetry.soファイルができてインストールされるので、有効化されるよう/etc/php/8.2/cli/conf.d/99-opentelemetry.iniを作る。

[opentelemetry]
extension=opentelemetry.so

これはベースができただけなので、対象に計装するにはSDKやライブラリに対応する計装パッケージを追加する必要があるようだ。今回は以下のようにした。

composer require open-telemetry/sdk open-telemetry/opentelemetry-auto-laravel open-telemetry/exporter-otlp

exporter-otlpが必要なのがちょっと罠だった。リストを見るとSymphonyやSlimのほか、WordPressなども。

Do you trust "tbachert/spi" to execute code and wish to enable it now? (writes "allow-plugins" to composer.json) [y,n,d,?]

はnでいいんだろうか。

ではzero-code計装で実行。OTEL_PHP_AUTOLOAD_ENABLED=trueで有効化されるので、わかりやすい。

OTEL_PHP_AUTOLOAD_ENABLED=true OTEL_SERVICE_NAME=php-zerocode php artisan serve

curlを叩いて、トレースを送る。

単なるリクエストではあるがORM経由でDBクエリのスパンも送られており、だいぶそれっぽいのが書き出されていて楽しげな雰囲気がある。0除算例外を起こしたところはエラーイベントも出力されていた。

せっかくなので、Mackerelでもどう見えるのか送ってみよう。

OpenTelemetry Collectorの設定を変更。
