CTERA products generate log messages upon various events. The log messages are divided by severity levels.
| Level | Required Response |
|---|---|
| Emergency | System is unusable. |
| Alert | Action must be taken immediately. |
| Critical | Critical condition. A situation such as storage nearing full capacity has occurred. Action should be taken as soon as possible. |
| Error | Error condition. Action must be taken as soon as possible. |
| Warning | Warning messages. An indication that an error may occur if action is not taken. |
| Notice | Normal but significant condition. |
| Info | Informational message. |
| Debug | Debug-level messages, useful for debugging and troubleshooting. |
Within each severity level, the log messages are divided in to topics. These topics enable you to understand the source of the message. For example, messages dealing with signing-in are included in the access topic.
Log messages are divided in to one of the following topics, added to the end of each log entry:
- access
- accounting
- allTopics
- antivirus
- audit
- backup
- cloudsync
- files
- sync
- system
