Identifying the type of configuration in use
If the performance monitoring infrastructure was installed previously, you might need to identify the type of configuration the system is currently using.
If the sensor configuration is managed automatically, the configuration is stored within IBM Spectrum Scale™. If it is managed automatically, it can be viewed with the mmperfmon config show command. The set of nodes where this configuration is enabled can be identified through the mmlscluster command. Those nodes where performance monitoring metrics collection is enabled are marked with the perfmon designation as shown in the following sample:
