FortiProxy priority levels

Each log entry contains a Level (level) field that indicates the estimated severity of the event that caused the log entry, such as level=warning, and therefore how high a priority it is likely to be. Level (level) associations with the descriptions below are not always uniform. They also may not correspond with your own definitions of how severe each event is. If you require notification when a specific event occurs, either configure SNMP traps or alert email by administrator-defined Severity Level (severity_level) or ID (logid), not by Level (level).

Level (0 is highest)	Name	Description
0	Emergency	The system is unusable or not responding.
1	Alert	Immediate action required. Used in security logs.
2	Critical	Functionality is affected.
3	Error	An error exists and functionality could be affected.
4	Warning	Functionality could be affected.
5	Notification	Information about normal events.
6	Information	General information about system operations. Used in event logs to record configuration changes.

For each location where the FortiProxy device can store log files (disk, memory, Syslog, or FortiAnalyzer), you can define a severity threshold. The FortiProxy unit stores all log messages equal to or exceeding the log severity level selected. For example, if you select Error, the FortiProxy unit will store log messages whose log severity level is Error, Critical, Alert, and Emergency.
