Note: When measuring the time consumed for DNS lookups, only lookups on external servers are considered. Cache lookups are disregarded. Detailed Performance Shows how the time consumed on average for processing a request throughout all cycles evolved during the selected interval Note: This performance information is only measured and displayed for web traffic that uses HTTP and HTTPS connections. The processing of a request throughout all cycles (request, response, and embedded object cycles) is considered to be one transaction. Average processing time is shown for complete transactions, but also for particular data transfers going on during a transaction: • First Byte Received from Client until First Byte Sent to Client – Shows the average processing time consumed between receiving the first byte from a client on the appliance and sending the first byte to this client within a transaction • Last Byte Received from Client until Last Byte Sent to Client – Shows the average processing time consumed between receiving the last byte received from a client on the appliance on and sending the last byte to this client within a transaction • First Byte Sent to Server until First Byte Received from Sever – Shows the average processing time consumed between sending the first byte from the appliance to a web server and receiving the first byte from this server within a transaction • Last Byte Sent to Server until Last Byte Received from Server – Shows the average processing time consumed between sending the last byte from the appliance to a web server and receiving the last byte from this server within a transaction
Logging Monitoring Logging 8 Appliance behavior can be recorded in log files. This section describes the available log file types, explains their handling, and gives an example of configuring a log file to record found viruses. Log file types There are several types of log files on the appliance. They differ in the type of data that is recorded and in the way the recording is done. Log files that record the same kind of data are stored in a folder, which is called a log. System log files Some log files are maintained by the appliance system, which includes the operating system and several system-related services. For these log files, data is recorded by system functions. You can view these files on the user interface, but not edit or delete them. Note: When system log files are unreadable, they are not shown on the user interface. The files are also rotated in regular intervals by the system. There is no option for configuring this rotation. Module log files Another type of log file is maintained by particular modules of the appliance, such as the proxy or anti-malware module. Data for these log files is recorded by module functions. You can view these files on the user interface, but not edit or delete them. Rotation, deletion, and pushing of these files is handled by the Log File Manager, which you can configure settings for. The files are stored in subfolders that are located on the appliance under /opt/mwg/log. All files in these folders are handled by the Log File Manager, except those that have mwgResInfo as a part of their names. The folders with the following names are also not handled by the Log File Manager: cores, feedbacks, tcpdump, migration, system, ruleengine_tracing, connection_tracing, message_tracing. Logs for module log files include the following: • Audit log — Stores log files that record changes to the appliance configuration • Debug log — Stores log files that record debugging information • Migration log — Stores log files that record migration activities • MWG errors logs — Stores log files that record errors occurring in modules of the appliance There are separate errors logs for the core and coordinator subsystems, the Anti-Malware module, the user interface, and the system configuration daemon. • Update log — Stores log files that record updates of modules and files on the appliance Rule-based log files There are also log files that record data based on rules. The recording is executed by events that are triggered when these rules apply. For example, a rule triggers an event when an object that a user requested is infected by a virus. The triggered event writes an entry with information on the user, the infected object, date and time of the request, and so on, to the log file. You can edit the rules for this type of log files in the same way as any other rules. The following rule-based log files are provided on the appliance by default: • Access log — Stores log files that record requests and related information, including date and time, user name, requested object, infection of an object, blocking of an object McAfee Web Gateway 7.1.5 Product Guide 277
