later.
38.4 Log Setting Screens
The Log Setting screens control log messages and alerts. A log message stores the
information for viewing (for example, in the View Log tab) or regular e-mailing later, and an
alert is e-mailed immediately. Usually, alerts are used for events that require more serious
attention, such as system errors and attacks.
The ZyWALL provides a system log and supports e-mail profiles and remote syslog servers.
The system log is available on the
View Log tab, the e-mail profiles are used to mail log
messages to the specified destinations, and the other four logs are stored on specified syslog
servers.
The Log Setting tab also controls what information is saved in each log. For the system log,
you can also specify which log messages are e-mailed, where they are e-mailed, and how often
they are e-mailed.
For alerts, the Log Settings tab controls which events generate alerts and where alerts are e-
mailed.
