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
| Attribute | Event types |
log | This is normal events. Note that if log-error is not set then this includes errors. |
log-error | This 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-debug | This 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. |
