Chapter 4 Configuring Virtual Contexts
Configuring Virtual Context Syslog Logging
The severity level that you specify indicates that you want syslog messages at that level and the more
severe levels. For example, if you specify Error, syslog displays Error, Critical, Alert, and Emergency
messages.
Note If you set all syslog levels to Debug, some commands like switchover are not processed
successfully. These commands are issued via the CLI and ACE Appliance Device Manager
cannot parse the returned prompt if Debug level is enabled. Instead, a timeout message is
displayed.
If you set syslog levels to Debug and then issue a command that results in a timeout message,
click Refresh to view the result of the operation.
Note Setting all syslog levels to Debug during normal operation can degrade overall performance.
Table 4-5 Virtual Context Syslog Configuration Attributes
Field Description Action
Enable Syslog This option indicates whether syslog
logging should be enabled or disabled.
Check the check box to enable syslog logging or clear
the check box to disable syslog logging.
Facility The syslog daemon uses the specified
syslog facility to determine how to
process the messages it receives. Syslog
servers file or direct messages based on
the facility number in the message.
For more information on the syslog
daemon and facility levels, refer to your
syslog daemon documentation.
Enter the facility appropriate for your network.
Valid entries are 16 (LOCAL0) through 23 (LOCAL7).
The default for an ACE appliance is 20 (LOCAL4).
Buffered Level This option enables system logging to a
local buffer and limits the messages sent
to the buffer based on severity.
Choose the desired level for sending system log
messages to a local buffer.
This option is disabled by default.
Console Level This option specifies the maximum level
for system log messages sent to the
console.
Select the desired level for sending system log
messages to the console.
This option is disabled by default.
Note Logging into the console can degrade system
performance. Therefore, we recommend that
you log messages to the console only when you
are testing or debugging problems. Do not use
this option when the network is busy, as it can
reduce ACE appliance performance.
