SPORE UI Backend Logging

The SPORE UI backend now includes a configurable logging system to reduce log noise while maintaining important information.

Log Levels

The logging system supports different levels:

INFO: Important operational messages (default)
DEBUG: Detailed debugging information (only shown when enabled)
WARN: Warning messages
ERROR: Error messages

Controlling Log Levels

Environment Variables

Set the LOG_LEVEL environment variable to control logging:

# Show only INFO, WARN, and ERROR messages (default)
LOG_LEVEL=info

# Show all messages including DEBUG
LOG_LEVEL=debug

Development Mode

In development mode (NODE_ENV=development), DEBUG messages are automatically enabled:

NODE_ENV=development npm start

What Was Changed

The following verbose logging has been moved to DEBUG level:

Heartbeat Messages: Regular heartbeat logs from nodes
WebSocket Broadcasts: Routine cluster update broadcasts
Proxy Calls: Individual API proxy request details
Cluster Updates: Member list change notifications
Discovery Events: Routine node discovery messages

Important Messages Still Shown

These messages remain at INFO level for operational visibility:

Node discovery (new nodes)
Node status changes (inactive/stale)
Failover events
Server startup/shutdown
Error conditions

Example Usage

# Production with minimal logging
LOG_LEVEL=info npm start

# Development with full debugging
LOG_LEVEL=debug npm start

# Or use development mode
NODE_ENV=development npm start

This reduces log noise significantly while preserving important operational information.
