About FortiVoice Gateway logging
FortiVoice Gateway can log multiple events. See FortiVoice Gateway log types.
You can select which severity level an activity or event must meet in order to be recorded in the logs. For more information, see Log message severity levels.
A FortiVoice Gateway can save log messages to its hard disk.

FortiVoice Gateway log types
FortiVoice Gateway can record system, voice, and fax log messages. You can view these logs from the Monitor > Log.

- Administration
- Configuration
- DHCP
- DNS
- HA
- Monitor
- System
- Voicemail
|
Avoid recording highly frequent log types such as voice logs to the local hard disk for an extended period of time. Excessive logging frequency can cause undue wear on the hard disk and may cause premature failure. |
Log message severity levels
Each log message contains a field that indicates the severity level of the log message, such as warning.
Log severity levels
|
Level |
Description |

| 2 - Critical | Indicates functionality is affected. |
| 3 - Error | Indicates an error condition exists and functionality could be affected. |
| 4 - Warning | Indicates functionality could be affected. |
| 5 - Notification | Provides information about normal events. |

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 a 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.
