# Event Log

ScreenOS provides an Event Log for monitoring system events on the security device. You can use the Event Log to view system events and gather information about hardware or software problems. The Event Log categorizes system events by severity level.

### The Event log Severity Levels Are as Follows:

### Alarm Level

EMERGENCY: Identifies critical attacks such as SYN attacks, Tear Drop attacks, and Ping of Death attacks. For more information on these types of attacks, see Screen Options.

ALERT: Identifies problems such as multiple user authentication failures and other attacks not included in the emergency category. For more information on various types of attacks, see Screen Options.

CRITICAL: Identifies events such as URL blocks, traffic alarms, high availability (HA) status changes, and global communications.

### Event Level

ERROR: Generates messages for admin name and password changes.

WARNING: Generates messages for admin logins and logouts, failures to log in and log out, and user authentication failures, successes, and timeouts.

NOTIFICATION: Generates messages for link status changes, load balancing server status changes, and traffic logs.

INFORMATION: Generates any kind of message not specified in other categories.

DEBUGGING: Generates all debugging messages. (See "Debug" commands in the ScreenOS CLI Reference Guide.)

The event log displays the following information for each event:

Date/Time: Indicates the date and time of the system event.

Level: Indicates the severity level of the system event.

Description: Describes the system events or changes and, if applicable, the source of the events.

You can save the Event log to your local hard drive or to a directory on your local area network for later viewing and analysis.
