DBService Log Overview¶
Log Description¶
Log path: The default storage path of DBService log files is /var/log/Bigdata/dbservice.
GaussDB: /var/log/Bigdata/dbservice/DB (GaussDB run log directory), /var/log/Bigdata/dbservice/scriptlog/gaussdbinstall.log (GaussDB installation log), and /var/log/gaussdbuninstall.log (GaussDB uninstallation log).
HA: /var/log/Bigdata/dbservice/ha/runlog (HA run log directory) and /var/log/Bigdata/dbservice/ha/scriptlog (HA script log directory)
DBServer: /var/log/Bigdata/dbservice/healthCheck (Directory of service and process health check logs)
/var/log/Bigdata/dbservice/scriptlog (run log directory), /var/log/Bigdata/audit/dbservice/ (audit log directory)
Log archive rule: The automatic DBService log compression function is enabled. By default, when the size of logs exceeds 1 MB, logs are automatically compressed into a log file named in the following format: <Original log file name>-[No.].gz. A maximum of 20 latest compressed files are reserved.
Note
Log archive rules cannot be modified.
