Configuring Virtual Context Syslog Logging
History Level
This option specifies the maximum level
for system log messages sent as traps to
an SNMP network management station.
Choose the desired level for sending system log
messages as traps to an SNMP network management
station.
This option is disabled by default.
Note For more information about configuring
SNMP, see the “Configuring SNMP
Notifications” section on page 4-25.
Monitor Level
This option specifies the maximum level
for system log messages sent to a remote
connection using Secure Shell (SSH) or
Telnet on the ACE appliance.
Select the desired level for sending system log
messages to a remote connection using SSH or Telnet
on the ACE appliance.
This option is disabled by default.
Note You must enable remote access on the ACE
appliance and establish a remote connection
using the SSH or Telnet protocol from a PC for
this option to work.
Persistence Level This option specifies the maximum level
for system log messages sent to Flash
memory.
Select the desired level for sending system log
messages to Flash memory.
This option is disabled by default.
Note We recommend that you use a lower severity
level, such as 3, since logging at a high rate to
Flash memory on the ACE appliance might
impact performance.
Trap Level This option specifies the maximum level
for system log messages sent to a syslog
server.
Select the desired level for sending system log
messages to a syslog server.
This option is disabled by default.
Queue Size This option specifies the size of the buffer
for storing syslog messages received
from other processes within the ACE
appliance while they await processing.
When the queue exceeds the specified
value, the excess messages are discarded.
Enter the desired queue size.
Valid entries are from 0 to 8192 messages.
The default is 100 messages.
Enable Timestamp This option indicates whether syslog
messages should include the date and
time that the message was generated.
Check the check box to enable timestamps on syslog
messages or clear the check box to disable timestamps
on syslog messages.
This option is disabled by default.
Enable Standby This option indicates whether logging is
enabled on the failover standby ACE
appliance. When enabled:
• This feature causes twice the
message traffic on the syslog server.
• The standby ACE appliance syslog
messages remain synchronized if
failover occurs.
Check the check box to enable logging on the failover
standby ACE appliance or clear the check box to
disable logging on the failover standby ACE
appliance.
