Log Levels¶
Table 2 describes the log levels provided by Manager. The priorities of log levels are FATAL, ERROR, WARN, INFO, and DEBUG in descending order. Logs whose levels are higher than or equal to the specified level are printed. The number of printed logs decreases as the specified log level increases.
Level | Description |
|---|---|
FATAL | Logs of this level record fatal error information about the current event processing that may result in a system crash. |
ERROR | Logs of this level record error information about the current event processing, which indicates that system running is abnormal. |
WARN | Abnormal information about the current event processing. These abnormalities will not result in system faults. |
INFO | Normal running status information about the system and events. |
DEBUG | Logs of this level record the system information and system debugging information. |
