Final answer:
The syslog severity levels range from 0-7, with 0 representing emergencies and 7 representing debugging. Each level corresponds to a different severity of log messages.
Step-by-step explanation:
The Syslog protocol is a standard protocol used by computer systems to send and receive log messages. It defines eight severity levels, represented by the numbers 0-7. These severity levels are used to prioritize and categorize log messages.
- Emergencies: Represented by level 0, these are the most severe and urgent messages that require immediate attention.
- Alerts: Level 1 messages indicate a condition that requires immediate action.
- Critical: Level 2 messages indicate critical conditions that may cause the system or application to become unavailable.
- Errors: Level 3 messages represent error conditions that are less severe than critical conditions but still require attention.
- Warnings: Level 4 messages indicate potential issues or conditions that might lead to errors if not addressed.
- Notifications: Level 5 messages provide information about normal system behavior.
- Informational: Level 6 messages provide general information about the system.
- Debugging: Level 7 messages are used for debugging and troubleshooting purposes.
