Description

Setting the following logging category to "debug" will open up some new logging information.

log4j.category.OpenEJB.server.discovery = debug

Or more specifically as:

log4j.category.OpenEJB.server.discovery.multipoint = debug
log4j.category.OpenEJB.server.discovery.multicast = debug

The nature of the debug output is to display all configuration information at startup:

DEBUG - Using default 'heart_rate=500'
DEBUG - Using default 'max_missed_heartbeats=10'
DEBUG - Using default 'max_reconnect_delay=30000'
DEBUG - Using default 'reconnect_delay=5000'
DEBUG - Using default 'exponential_backoff=0'
DEBUG - Using default 'max_reconnect_attempts=10'
INFO - Created Tracker

{group='default', groupPrefix='default:', heartRate=500, maxMissedHeartbeats=10, reconnectDelay=5000, maxReconnectDelay=30000, maxReconnectAttempts=10, exponentialBackoff=0, useExponentialBackOff=false, registeredServices=0, discoveredServices=0}

As well as any events at runtime:

DEBUG - Expired Service

{uri=green://localhost:0, broadcastString='default:green://localhost:0'}

Timeout

{lastSeen=-5005, threshold=5000}

DEBUG - Added Service

{uri=green://localhost:0}

DEBUG - Removed Service

{uri=green://localhost:0}
