Log Destinations
Both event logs and accounting logs use a common mechanism for referencing a log destination.
routerssupport the following log destinations:
• Console on page 300
• Session on page 300
• Memory Logs on page 300
• Log Files on page 301
• SNMP Trap Group on page 303
• Syslog on page 303
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 event log is removed. Event logs configured with a session destination are not
stored in the configuration file. 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.
