# Heartbeat Daemon Multi-Threshold Configuration Example
# ==============================================================================
# This file demonstrates the new multi-threshold configuration feature that allows
# different threshold settings for different hosts/clients.
#
# Features:
#   - Define multiple named threshold configurations
#   - Map specific hosts to specific threshold configurations
#   - Set a default configuration for unmapped hosts
#   - Backward compatible with single threshold configuration
# ==============================================================================

# Global threshold settings
threshold_renotify_interval: 3600  # Re-notify every hour for ongoing alerts (seconds)

# Optional: Set default threshold config (defaults to "default" if not specified)
default_threshold_config: "default"

# ----------------------------------------------------------------------------
# Multiple Named Threshold Configurations
# ----------------------------------------------------------------------------
# Define multiple threshold configurations with different sensitivity levels
threshold_configs:
  
  # Default configuration - moderate thresholds for most servers
