Log Destinations
Both event logs and accounting logs use a common mechanism for referencing a log destination.
routers support the following log destinations:
•
•
•
•
•
•
Only a single log destination can be associated with an event log or with an accounting log. An
event log can be associated with multiple event sources, but it can only have a single log
destination.
A file destination is the only type of log destination that can be configured for an accounting log.
Console
Sending events to a console destination means the message will be sent to the system console The
console device can be used as an event log destination.
Session
A session destination is a temporary log destination which directs entries to the active telnet or
SSH session for the duration of the session. When the session is terminated, for example, when the
user logs out, the "to session" configuration is removed. Event logs configured with a session
destination are stored in the configuration file but the "to session" part is not stored. Event logs can
direct log entries to the session destination.

Memory Logs

A memory log is a circular buffer. When the log is full, the oldest entry in the log is replaced with
the new entry. When a memory log is created, the specific number of entries it can hold can be
specified, otherwise it will assume a default size. An event log can send entries to a memory log
destination.
