Log message severity levels
Each log message contains a field that indicates the severity level of the log message, such as
warning.
Table 8: Log severity levels
Levels
0 - Emergency
1 - Alert
2 - Critical
3 - Error
4 - Warning
5 - Notification
6 - Information
6 - Debug
For each location where the FortiVoice Gateway can store log files, you can define the severity
threshold of the log messages to be stored there.
Avoid recording log messages using low severity thresholds such as Information or
Notification to the local hard disk for an extended period of time. A low log severity threshold
is one possible cause of frequent logging. Excessive logging frequency can cause undue wear
on the hard disk and may cause premature failure.
The FortiVoice Gateway stores all log messages equal to or exceeding the severity level you
select. For example, if you select Error, the FortiVoice Gateway stores log messages whose
severity level is Error, Critical, Alert, or Emergency.
Configuring logging
The Log Settings submenu lets you:
• set the severity level
• configure which types of log messages to record
This section includes the following topics:
•
Configuring logging to the hard disk
•
Choosing which events to log
Configuring logging to the hard disk
You can store log messages locally on the hard disk of the FortiVoice Gateway.
To ensure that the local hard disk has sufficient disk space to store new log messages and that
it does not overwrite existing logs, you should regularly download backup copies of the oldest
log files to your management computer or other storage, and then delete them from the
FortiVoice Gateway.
You can view and download these logs from the Log submenu of the Monitor tab. For more
