This chapter describes the commands used for configuring logging.
Logging Overview
Two types of log messages exist in the SafeGuard device: trace messages and syslog
messages.
■ Trace messages provide developers with debugging information for the product
in the field. This information is primarily used by the system engineers and TAC
to diagnose problems.
■ Syslog messages inform the user of normal operational events.
Each message in the system has a type, severity level, and source component. The
severity levels are shown in the table that follows:
Ta ble 3 2 describes security levels and their severity.
Each component in the system is identified by a string name. Each component can have
independent threshold levels for both trace and syslog messages.
