# VMPooler Configuration Example with Dead-Letter Queue, Auto-Purge, and Health Checks

# Redis Configuration
:redis:
  server: 'localhost'
  port: 6379
  data_ttl: 168  # hours - how long to keep VM metadata in Redis
  
  # Dead-Letter Queue (DLQ) Configuration
  dlq_enabled: true
  dlq_ttl: 168  # hours (7 days) - how long to keep DLQ entries
  dlq_max_entries: 10000  # maximum entries per DLQ queue before trimming

# Application Configuration
:config:
  # ... other existing config ...
  
  # Dead-Letter Queue (DLQ) - Optional, defaults shown
  dlq_enabled: false  # Set to true to enable DLQ
  dlq_ttl: 168  # hours (7 days)
  dlq_max_entries: 10000  # per DLQ queue
  
  # Auto-Purge Stale Queue Entries
  purge_enabled: false  # Set to true to enable auto-purge
  purge_interval: 3600  # seconds (1 hour) - how often to run purge cycle
  purge_dry_run: false  # Set to true to log what would be purged without actually purging
  
  # Auto-Purge Age Thresholds (in seconds)
  max_pending_age: 7200  # 2 hours - VMs stuck in pending
  max_ready_age: 86400  # 24 hours - VMs idle in ready queue
  max_completed_age: 3600  # 1 hour - VMs in completed queue
  max_orphaned_age: 86400  # 24 hours - orphaned VM metadata
  max_request_age: 86400  # 24 hours - stale on-demand requests
  
  # Health Checks
  health_check_enabled: false  # Set to true to enable health checks
  health_check_interval: 300  # seconds (5 minutes) - how often to run health checks
  
  # Health Check Thresholds
  health_thresholds:
    pending_queue_max: 100  # Warning threshold for pending queue size
    ready_queue_max: 500  # Warning threshold for ready queue size
    dlq_max_warning: 100  # Warning threshold for DLQ size
    dlq_max_critical: 1000  # Critical threshold for DLQ size
    stuck_vm_age_threshold: 7200  # 2 hours - age at which VM is considered "stuck"
    stuck_vm_max_warning: 10  # Warning threshold for stuck VM count
    stuck_vm_max_critical: 50  # Critical threshold for stuck VM count

# Pool Configuration
:pools:
  - name: 'centos-7-x86_64'
    size: 5
    provider: 'vsphere'
    # ... other pool settings ...

# Provider Configuration
:providers:
  :vsphere:
    server: 'vcenter.example.com'
    username: 'vmpooler'
    password: 'secret'
    # ... other provider settings ...

# Example: Production Configuration
# For production use, you might want:
# :config:
#   dlq_enabled: true
#   dlq_ttl: 168  # Keep failed VMs for a week
#   
#   purge_enabled: true
#   purge_interval: 1800  # Run every 30 minutes
#   purge_dry_run: false
#   max_pending_age: 3600  # Purge pending VMs after 1 hour
#   max_ready_age: 172800  # Purge ready VMs after 2 days
#   
#   health_check_enabled: true
#   health_check_interval: 300  # Check every 5 minutes

# Example: Development Configuration
# For development/testing, you might want:
# :config:
#   dlq_enabled: true
#   dlq_ttl: 24  # Keep failed VMs for a day
#   
#   purge_enabled: true
#   purge_interval: 600  # Run every 10 minutes
#   purge_dry_run: true  # Test mode - log but don't actually purge
#   max_pending_age: 1800  # More aggressive - 30 minutes
#   
#   health_check_enabled: true
#   health_check_interval: 60  # Check every minute
