Log Level & Telemetry Configuration Page

Create an Angular page for configuring logging levels and OpenTelemetry tracing using the existing log and telemetry infrastructure.

Backend Endpoints Needed

GET    /admin/log/config          — Current log configuration (level, format)
PUT    /admin/log/config          — Update log configuration
GET    /admin/log/tail?lines=N    — Tail recent log entries
GET    /admin/telemetry/config    — Current telemetry configuration
PUT    /admin/telemetry/config    — Update telemetry configuration
GET    /admin/telemetry/spans     — Recent trace spans (if captured)

UI Requirements

Log Configuration

• Log Level: Dropdown (TRACE, DEBUG, INFO, WARN, ERROR, OFF)
• Per-Module Levels: Table to set different levels per module
• Log Format: JSON or plain text
• Output: stdout, file, or both

Live Log Viewer

• Tail: Real-time log tail feed (via WebSocket or polling)
• Filter: By level, module, or search text
• Highlight: Color-coded log levels
• Pause/Resume: Freeze the feed to inspect
• Copy: Copy log entries to clipboard

Telemetry Configuration

• Tracing: Enable/disable OpenTelemetry tracing
• Sampling Rate: Percentage of requests to trace
• Export Endpoint: OTLP endpoint URL
• Service Name: Service identifier for traces

Acceptance Criteria

• Log level dropdown changes are reflected
• Per-module log level configuration works
• Log tail shows recent entries
• Log entries are color-coded by level
• Telemetry config can be viewed and updated
• Error states for API failures
