Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

An important feature of the Cisco IronPort Email Security appliance is its logging capabilities. AsyncOS 
can generate many types of logs, recording varying types of information. Log files contain the records 
of regular activity and errors from various components of the system. This information can be valuable 
when monitoring your Cisco IronPort appliance as well as when troubleshooting or checking 
performance.

Logs are a compact, efficient method of gathering critical information about the email operations of 
AsyncOS. These logs record information regarding activity on your Cisco IronPort appliance. The 
information will vary depending upon the log you view, for example, Bounce logs or Delivery logs.

Most logs are recorded in plain text (ASCII) format; however, delivery logs are formatted in binary for 
resource efficiency. The ASCII text information is readable in any text editor.

Cisco offers an off-box centralized reporting and tracking tool for logs from multiple Cisco IronPort 
appliances. See your Cisco IronPort representative for more information.

A log subscription associates a log type with a name, logging level, and other constraints such as size 
and destination information; multiple subscriptions for the same log type are permitted.
