APAR status

  • Closed as program error.

Error description

  • The z/VSE SNMP Monitoring Agent returns incorrect CPU-time
    values when the system is running with CPU balancing active.
    Whenever the CPU balancing algorithm starts or stops CPUs the
    CPU-time value reported by the SNMP Monitoring Agent is
    incorrect.
    

Local fix

  • Deactivate CPU Balancing.

    The z/VSE SNMP Monitoring Agent returns incorrect CPU-time
    values when the system is running with CPU balancing active.
    Whenever the CPU balancing algorithm starts or stops CPUs the
    CPU-time value reported by the SNMP Monitoring Agent is
    incorrect.
    

Problem conclusion

  • The CPU plugin has been updated to correctly add up the CPU-time
    used for all CPUs, when CPU balancing is active.
