OpenStack services use standard logging levels such as TRACE, DEBUG, INFO, AUDIT, WARNING, ERROR, and CRITICAL. The log messages appear in the logs only if they are more severe than the particular log level. The log files are saved to the respective sub-directory at /var/log directory.
OpenTracing is enabled on the Extreme Fabric Automation application to provide end-to-end traceability. The EFA logs are available as part of SupportSave.
