System Event Log Manager
System events are configured via the file /opt/nem/voyager/etc/eventlogmanager-system.properties.
The file provides the following configuration options:
# System Event Manager configuration
#
# nem.eventlogmanager.backends.syslog.enabled=true
# nem.eventlogmanager.logRotation.enabled=true
# nem.eventlogmanager.logRotation.threshold=100000
# nem.eventlogmanager.logRotation.purgePercent=20
# nem.eventlogmanager.logRotation.purgeFile.path=var/log
# nem.eventlogmanager.logRotation.purgeFile.namePrefix=events
# nem.eventlogmanager.logRotation.purgeFile.nameExtension=eventDump.log
System Event Log Manager applies a log rotation policy to the database entries. When the number of events in the database exceeds pre-defined threshold (by default, 10000 entries), the oldest 20% of events are saved to a file(s) in the /opt/nem/var/log directory. The saved events are distributed to the files in such way that events from each day are grouped in a separate file.
