Hue Log Overview
Log Description
Log paths: The default paths of Hue logs are /var/log/Bigdata/hue (for storing run logs) and /var/log/Bigdata/audit/hue (for storing audit logs).
Log archive rules: The automatic compression and archiving function of the Hue logs is enabled. By default, when the size of a log file (access.log, error.log, runcpserver.log, or hue-audits.log) exceeds 5 MB, logs are automatically compressed. A maximum of 20 latest compressed files are reserved. The number of compressed files and compression threshold can be configured.

Log Level
Table 2 describes the log levels supported by Hue.
Levels of logs are ERROR, WARN, INFO, and DEBUG from the highest to the lowest priority. Run logs of equal or higher levels are recorded. The higher the specified log level, the fewer the logs recorded.
Level |
Description |
---|---|
ERROR |
Logs of this level record error information about system running. |
WARN |
Logs of this level record exception information about the current event processing. |
INFO |
Logs of this level record normal running status information about the system and events. |
DEBUG |
Logs of this level record the system information and system debugging information. |
To modify log levels, perform the following operations:
- Go to the All Configurations page of the Hue service by referring to Modifying Cluster Service Configuration Parameters.
