5.2. Enabling logging

Event logging is enabled by setting one of the attributes shown in Table 5.1 on the appropriate object(s) in the configuration, which depends on what event(s) you are interested in. The attribute value specifies the name of the log target to send the event message to. The events that cause a log entry will naturally depend on the object on which you enable logging. Some objects have additional attributes such as log-error for unusual events, and log-debug for extra detail.

Table 5.1. Logging attributes

AttributeEvent types
logThis is normal events. Note that if log-error is not set then this includes errors.
log-errorThis is when things happen that should not. It could be something as simple as bad login on telnet. Note that if log-error is not set but log is set then errors are logged to the log target by default.
log-debugThis is extra detail and is normally only used when diagnosing a problem. Debug logging can be a lot of information, for example, in some cases whole packets are logged (e.g. PPP). It is generally best only to use debug logging when needed.
