Sending Event Messages To Log Targets - Extreme Networks ExtremeWare XOS Guide Manual

— Matching parameters (for example, only messages with source IP addresses in the 10.1.2.0/24
subnet)
— Severity level (for example, only messages of severity critical, error, or warning)
• Change the format of event messages (for example, display the date as "12-May-2003" or
"2003-05-12")
• Display log messages in real-time, and filter the messages that are displayed, both on the console
and from telnet sessions
• Display stored log messages from the memory buffer or NVRAM
• Upload event logs stored in memory buffer or NVRAM to a TFTP server
• Display counts of event occurrences, even those not included in filter
• Display debug information, using a consistent configuration method

Sending Event Messages to Log Targets

Five types of targets can receive log messages:
• Console display
• Current session (telnet or console display)
• Memory buffer (can contain 200-20,000 messages)
• NVRAM (messages remain after reboot)
• Syslog host
The first four types of targets exist by default, but before enabling any syslog host, the host's
information needs to be added to the switch using the
Networks EPICenter can be a syslog target.
By default, the memory buffer and NVRAM targets are already enabled and receive messages. To start
sending messages to the targets, use the following command:
enable log target [console | memory-buffer | nvram | session | syslog [all |
ipaddress] [local0 ... local7]]]
After it has been enabled, the target receives the messages it is configured for. See "Target
Configuration" later in this chapter for information on viewing the current configuration of a target. The
memory buffer can only contain the configured number of messages, so the oldest message is lost when
a new message arrives, and the buffer is full.
Use the following command to stop sending messages to the target:
disable log target [console | memory-buffer | nvram | session | syslog [all |
<ipaddress> ] [local0 ... local7]]]
NOTE
Refer to your UNIX documentation for more information about the syslog host facility.
