The Event Log and History Files
Introduction
The system event log records various system activities and events such as uploads and downloads etc.
Events are logged in the database as long as the number of events does not exceed the value “nem.eventlogmanager.logRotation.threshold” specified in the file
/opt/nem/voyager/etc/eventlogmanager-system.properties
The default value for “max_nof_events” is 100’000.
The events stored in the database can be viewed via the NEM Desktop menu “System – Event List”.
The current system event log file has the name
• nem-system-event.log,
and is located in the same directory as the alarm log file, i.e. /opt/nem/var/log.
Further event logs are available with the files
• nem-security-event.log
• nem-bp-eventchannel.log
• nem-bp-eventlogmanager-security.log
• nem-bp-eventlogmanager-system.log
Event log settings for security events and for the NEMSEC database are in the properties files
/opt/nem/voyager/etc/eventlogmanager-security.properties
and
/opt/nem/voyager/etc/eventlogmanager-ensure-sec-db.properties
respectively.
Log, trace and *.txt files are rotated to prevent filling up disk space. For more information refer to the product description “FOXMAN‑UN Logging Feature” [1KHW029166], section “Log, Trace and *.txt File Rotation Definitions”.
Please note:
When restoring a database, the events stored in the backup database are restored as well. This will hence reset the event counter. If the number of events stored in the database is smaller than the maximum allowed, this will lead to creation of empty daily event history files until the maximum number of events stored in the database is reached again.
For more details on logging and on forwarding events to a syslog server refer to the product description “FOXMAN‑UN Logging Feature” [1KHW029166].
