Monitoring the Firewall Services Module
The preceding example states that syslog messages that match the criteria specified will be sent to the
output destination. The specified criteria for syslog messages to be included in the list are:
•
•

A syslog message is logged if it satisfies any of these conditions. If a syslog message satisfies more than
one of the conditions, the message is logged only once.

Configuring the Logging Queue
The FWSM has a fixed number of blocks in memory that can be allocated for buffering syslog messages
while they are waiting to be sent to the configured output destination. The number of blocks required
depends on the length of the syslog message queue and the number of syslog servers specified.
To specify the number of syslog messages the FWSM can hold in its queue before sending them to the
configured output destination, enter the following command:
hostname(config)# logging queue message_count
where the message_count variable specifies the number of syslog messages that can remain in the syslog
message queue while awaiting processing. The default is 512 syslog messages. A setting of 0 (zero)
indicates unlimited syslog messages, that is, the queue size is limited only by block memory availability.
To view the queue and queue statistics, enter the following command:
hostname(config)# show logging queue
Including the Date and Time in Syslog Messages
To specify that syslog messages should include the date and time that the syslog messages was generated,
enter the following command:
hostname(config)# logging timestamp
