+# Management API - Logged Events Reference
+
+This document provides a comprehensive list of all logged events in the Management API service. Events are organized by source file and log level to help with monitoring, debugging, and understanding the API's behavior.
+
+The Management API uses Go's standard `log/slog` library for structured logging. Each event includes contextual information such as instance ID, user ID, and relevant resource identifiers.
+
+## Log Levels
+
+- **Info**: Informational messages about normal operations
+- **Warn**: Warning messages about potentially problematic situations
+- **Error**: Error messages indicating failures that need attention
+- **Debug**: Detailed debugging information (usually for development)
+

+## Summary
+
+This document lists **350 unique log events** across **9 source files** in the Management API service. The events are categorized into:
+
+- **Info Events**: Normal operational events (primary focus for monitoring workflow)
+- **Warn Events**: Warnings about potentially problematic situations (authentication failures, validation errors)
+- **Error Events**: Errors requiring attention (database failures, parsing errors)
+- **Debug Events**: Detailed debugging information (typically for development)
+
+### Usage
+
+When monitoring or debugging the Management API:
+
+1. **Info events** help track normal operations and user activities
+2. **Warn events** indicate potential security issues or invalid requests
+3. **Error events** require investigation and potential fixes
+4. **Debug events** provide additional context during troubleshooting
+
+### Contextual Information
+
+Most log events include contextual attributes such as:
+- `instanceID`: The instance being accessed
+- `userID` or `Subject`: The user performing the action
+- `studyKey`: The study being operated on
+- `error`: Error details when operations fail
+- Resource-specific identifiers (participantID, surveyKey, etc.)
+
+This structured logging enables effective filtering and analysis in log aggregation systems.
