Trace facility

The IBM Spectrum Scale™ system includes many different trace points to facilitate rapid problem determination of failures.

IBM Spectrum Scale tracing is based on the kernel trace facility on AIX®, embedded GPFS™ trace subsystem on Linux, and the Windows ETL subsystem on Windows. The level of detail that is gathered by the trace facility is controlled by setting the trace levels using the mmtracectl command.

The mmtracectl command sets up and enables tracing using default settings for various common problem situations. Using this command improves the probability of gathering accurate and reliable problem determination information. For more information, see the mmtracectl command.
