Cisco Cisco Web Security Appliance S170 사용자 가이드

You can use log files to monitor web traffic. To configure the appliance to create log files, you create log 
subscriptions. A log subscription is an appliance configuration that associates a log file type with a name, 
logging level, and other parameters, such as size and destination information. You can subscribe to a 
variety of log file types. For more information about log subscriptions, see 

.

In typical appliance monitoring, the appliance administrator usually reads the following log files:

Access log. Records all Web Proxy filtering and scanning activity. For more information about the 
access log, see 

.

Traffic Monitor log. Records all L4 Traffic Monitor activity. For more information about the traffic 
monitor log, see 

.

The appliance also creates other log file types, such as the system log file. You might want to read other 
log files to troubleshoot appliance errors. For a list of each type, see 

The appliance provides several options for customizing the type of information recorded in the access 
log. For more information, see 

The log file type indicates what information is recorded in the generated log, such as web traffic or 
system data. By default, the Web Security appliance has log subscriptions for most log file types already 
created. However, there are some log file types that specific to troubleshooting the Web Proxy. Those 
logs are not created by default. For more information on those log file types, see
