About FortiVoice logging

FortiVoice units can log multiple events. See FortiVoice 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 unit can save log messages to its hard disk or a remote location, such as a Syslog server or a FortiAnalyzer unit. For more information, see Configuring logging. It can also use log messages as the basis for reports. For more information, see Configuring call center report profiles and generating reports.

FortiVoice log types

FortiVoice units can record the following types of log messages. The Event log also contains several subtypes. You can view these logs from Monitor > Log.

Log types

Log type	Subtype	Description
System	Configuration change Admin activity System activity HA DHCP Monitor Voice mail DNS	Includes system and administration events, such as downloading a backup copy of the configuration. Also includes voicemail, FortiVoice unit monitoring, and DNS events.
Generic	SMTP Activity	Includes SMTP server events.
Voice		Includes phone call events.
Fax		Includes fax events.
DTMF		Includes DTMF (Dual Tone Multi-Frequency) events.
Hotel		Includes hotel management events, such as guest check-in and check-out.
Call center	IVR	Includes call center IVR events.
	AGT	Includes call center agent events.

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

Levels	Description
0 - Emergency	Indicates the system has become unusable.
1 - Alert	Indicates immediate action is required.
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.
6 - Information	Provides general information about system operations.
6 - Debug	Provides information useful to debug a problem.

For each location where the FortiVoice unit 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 unit stores all log messages equal to or exceeding the severity level you select. For example, if you select Error, the FortiVoice unit stores log messages whose severity level is Error, Critical, Alert, or Emergency.
