Performance monitoring limitations

The following section lists the limitations of the performance monitoring tool:

  • Performance monitoring is not supported on the following operating systems:
    • x86_64/sles11
    • ppc64le/Ubuntu14.04
    • ppc64/aix
  • The interface for NFS of the performance monitoring tool does not work on SLES 11 nodes.
  • Start of change The performance monitoring tool does not support systems with mixed endianness. For example, big-endian nodes (s390x) and little-endian nodes (x86_64 or ppc64le) are not supported in the same cluster.End of change
Important: When you are using the performance monitoring tool, ensure that the clocks of all the nodes in the cluster are synchronized. It is recommended to configure the Network Time Protocol (NTP) on all nodes.
