Rate Limit
The Rate Limit pane lets you specify the number of syslog messages that the firewall can send. You can
specify a rate limit for message logging levels or limit the rate of a specific message. The rate level is
applied to the severity level or to the message ID, not to a destination. Therefore, rate limits affect the
volume of messages being sent to all configured destinations. To access this pane, choose Configuration
> Device Management > Logging > Rate Limit.
