+# OpenTelemetry Custom Metrics Architecture
+
+## 概要
+
+GROWIのOpenTelemetryカスタムメトリクスは、以下の3つのカテゴリに分類して実装されています：
+
+1. **Resource Attributes** - システム起動時に設定される静的情報
+2. **Config Metrics** - 設定変更により動的に変わる可能性があるメタデータ
+3. **Custom Metrics** - 時間と共に変化する業務メトリクス
+
+## アーキテクチャ
+
+### Resource Attributes
+
+静的なシステム情報をOpenTelemetryのResource Attributesとして設定します。Resource Attributesは2段階で設定されます：
+
+1. **起動時設定**: OS情報など、データベースアクセスが不要な静的情報
+2. **データベース初期化後設定**: アプリケーション情報など、データベースアクセスが必要な情報
+
+#### 実装場所
+```
+src/features/opentelemetry/server/custom-resource-attributes/
+├── os-resource-attributes.ts        # OS情報 (起動時設定)
+└── application-resource-attributes.ts  # アプリケーション固定情報 (DB初期化後設定)
+```
+
+#### OS情報 (`os-resource-attributes.ts`) - 起動時設定
+- `os.type` - OS種別 (Linux, Windows等)
+- `os.platform` - プラットフォーム (linux, darwin等)
+- `os.arch` - アーキテクチャ (x64, arm64等)
+- `os.totalmem` - 総メモリ量
+
+#### アプリケーション固定情報 (`application-resource-attributes.ts`) - DB初期化後設定
+- `growi.service.type` - サービスタイプ
+- `growi.deployment.type` - デプロイメントタイプ
+- `growi.attachment.type` - ファイルアップロードタイプ
+- `growi.installedAt` - インストール日時
+- `growi.installedAt.by_oldest_user` - 最古ユーザー作成日時
+
+### Config Metrics
+
+設定変更により動的に変わる可能性があるメタデータ実装します。値は常に1で、情報はラベルに格納されます。
+
+#### 実装場所
+```
+src/features/opentelemetry/server/custom-metrics/application-metrics.ts
+```
+
+#### 収集される情報
+- `service_instance_id` - サービスインスタンス識別子
+- `site_url` - サイトURL
+- `wiki_type` - Wiki種別 (open/closed)
+- `external_auth_types` - 有効な外部認証プロバイダー
+
+#### メトリクス例
+```
+growi_info{service_instance_id="abc123",site_url="https://wiki.example.com",wiki_type="open",external_auth_types="github,google"} 1
+```
+
+### Custom Metrics
+
+時間と共に変化する業務メトリクスを実装します。数値として監視・アラートの対象となるメトリクスです。
+
+#### 実装場所
+```
+src/features/opentelemetry/server/custom-metrics/
+├── application-metrics.ts  # Config Metrics (既存)
+└── user-counts-metrics.ts  # ユーザー数メトリクス (新規作成)
+```
+
+#### ユーザー数メトリクス (`user-counts-metrics.ts`)
+- `growi.users.total` - 総ユーザー数
+- `growi.users.active` - アクティブユーザー数
+
+## 収集間隔・設定タイミング
+
+### Resource Attributes
+- **OS情報**: アプリケーション起動時に1回のみ設定
+- **アプリケーション情報**: データベース初期化後に1回のみ設定
+
+### Metrics
+- **Config Metrics**: 60秒間隔で収集 (デフォルト)
+- **Custom Metrics**: 60秒間隔で収集 (デフォルト)
+
+### 2段階設定の理由
+
+Resource Attributesが2段階で設定される理由：
+
+1. **循環依存の回避**: アプリケーション情報の取得にはgrowiInfoServiceが必要だが、OpenTelemetry初期化時点では利用できない
+2. **データベース依存**: インストール日時やサービス設定などはデータベースから取得する必要がある
+3. **起動時間の最適化**: データベース接続を待たずにOpenTelemetryの基本機能を開始できる
+
+## 設定の変更
+
+メトリクス収集間隔は `PeriodicExportingMetricReader` の `exportIntervalMillis` で変更可能です：
+
+```typescript
+metricReader: new PeriodicExportingMetricReader({
+  exporter: new OTLPMetricExporter(),
+  exportIntervalMillis: 30000, // 30秒間隔
+}),
+```
+
+## 使用例
+
+### Prometheusでのクエリ例
+
+```promql
+# 総ユーザー数の推移
+growi_users_total
+
+# Wiki種別でグループ化した情報
+growi_info{wiki_type="open"}
+
+# 外部認証を使用しているインスタンス
+growi_info{external_auth_types!=""}
+```
+
+### Grafanaでの可視化例
+
+- ユーザー数の時系列グラフ
+- Wiki種別の分布円グラフ
+- 外部認証プロバイダーの利用状況

+# OpenTelemetry Custom Metrics Implementation Guide
+
+## 改修実装状況
+
+### ✅ 完了した実装
+
+#### 1. Resource Attributes
+- **OS情報**: `src/features/opentelemetry/server/custom-resource-attributes/os-resource-attributes.ts`
+  - OS種別、プラットフォーム、アーキテクチャ、総メモリ量
+  - 起動時に設定
+- **アプリケーション固定情報**: `src/features/opentelemetry/server/custom-resource-attributes/application-resource-attributes.ts`
+  - サービス・デプロイメントタイプ、添付ファイルタイプ、インストール情報
+  - データベース初期化後に設定
+
+#### 2. Config Metrics
+- **実装場所**: `src/features/opentelemetry/server/custom-metrics/application-metrics.ts`
+- **メトリクス**: `growi.configs` (値は常に1、情報はラベルに格納)
+- **収集情報**: サービスインスタンスID、サイトURL、Wiki種別、外部認証タイプ
+
+#### 3. Custom Metrics
+- **実装場所**: `src/features/opentelemetry/server/custom-metrics/user-counts-metrics.ts`
+- **メトリクス**: 
+  - `growi.users.total` - 総ユーザー数
+  - `growi.users.active` - アクティブユーザー数
+
+#### 4. 統合作業
+- **node-sdk-configuration.ts**: OS情報のResource Attributes統合済み
+- **node-sdk.ts**: データベース初期化後のアプリケーション情報設定統合済み
+- **メトリクス初期化**: Config MetricsとCustom Metricsの初期化統合済み
+
+### 📋 実装済みの統合
+
+#### Resource Attributesの2段階設定
+
+**1段階目 (起動時)**: `generateNodeSDKConfiguration`
+```typescript
+// OS情報のみでResourceを作成
+const osAttributes = getOsResourceAttributes();
+resource = resourceFromAttributes({
+  [ATTR_SERVICE_NAME]: 'growi',
+  [ATTR_SERVICE_VERSION]: version,
+  ...osAttributes,
+});
+```
+
+**2段階目 (DB初期化後)**: `setupAdditionalResourceAttributes`
+```typescript
+// アプリケーション情報とサービスインスタンスIDを追加
+const appAttributes = await getApplicationResourceAttributes();
+if (serviceInstanceId != null) {
+  appAttributes[ATTR_SERVICE_INSTANCE_ID] = serviceInstanceId;
+}
+const updatedResource = await generateAdditionalResourceAttributes(appAttributes);
+setResource(sdkInstance, updatedResource);
+```
+
+#### メトリクス収集の統合
+```typescript
+// generateNodeSDKConfiguration内で初期化
+addApplicationMetrics();
+addUserCountsMetrics();
+```
+

+
+## 設計のポイント
+
+1. **2段階Resource設定**: データベース依存の情報は初期化後に設定して循環依存を回避
+2. **循環依存の回避**: 動的importを使用してgrowiInfoServiceを読み込み
+3. **エラーハンドリング**: 各メトリクス収集でtry-catchを実装
+4. **型安全性**: Optional chainingを使用してundefinedを適切に処理
+5. **ログ出力**: デバッグ用のログを各段階で出力
+6. **起動時間の最適化**: データベース接続を待たずにOpenTelemetryの基本機能を開始

+### Unstable SemConv
+
+<!-- Dev Note: ^^ This '#unstable-semconv' anchor is being used in jsdoc links in the code. -->
+
+Because the "incubating" entry-point may include breaking changes in minor versions, it is recommended that instrumentation libraries **not** import `@opentelemetry/semantic-conventions/incubating` in runtime code, but instead **copy relevant definitions into their own code base**. (This is the same [recommendation](https://opentelemetry.io/docs/specs/semconv/non-normative/code-generation/#stability-and-versioning) as for other languages.)
+
+For example, create a "src/semconv.ts" (or "lib/semconv.js" if implementing in JavaScript) file that copies from [experimental_attributes.ts](./src/experimental_attributes.ts) or [experimental_metrics.ts](./src/experimental_metrics.ts):
+
+```ts
+// src/semconv.ts
+export const ATTR_DB_NAMESPACE = 'db.namespace';
+export const ATTR_DB_OPERATION_NAME = 'db.operation.name';
+```
+
+```ts
+// src/instrumentation.ts
+import {
+  ATTR_SERVER_PORT,
+  ATTR_SERVER_ADDRESS,
+} from '@opentelemetry/semantic-conventions';
+import {
+  ATTR_DB_NAMESPACE,
+  ATTR_DB_OPERATION_NAME,
+} from './semconv';
+
+span.setAttributes({
+  [ATTR_DB_NAMESPACE]: ...,
+  [ATTR_DB_OPERATION_NAME]: ...,
+  [ATTR_SERVER_PORT]: ...,
+  [ATTR_SERVER_ADDRESS]: ...,
+})
+```
+
+Occasionally, one should review changes to `@opentelemetry/semantic-conventions` to see if any used unstable conventions have changed or been stabilized. However, an update to a newer minor version of the package will never be breaking.
