APAR status

  • Closed as program error.

Error description

  • When the Hybrid gateway is used in an ITM environment to bridge
    data from itmv6 to APM v8, excessive cpu in the IBM Tivoli
    Portal's ewas will occur when sending data from ITM6 to APMv8.
    

Local fix

  • None. Internal defect 216549 was opened to address this
    performance problem. This apar will reference that internal
    defect.
    

Problem summary

  • When the Hybrid Gateway feature of APM 8.x is used to connect an
     APM 8.x system to ITM, the CPU utilization of the Tivoli
    Enterprise Portal Server can spike, possibly affecting the
    throughput of other ITM workloads associated flowing through the
     Tivoli Enterprise Portal Server.
    
    
    This CPU utilization problem can sometimes be observed when the
    Hybrid Gateway is used to retrieve agent metric information from
    agents at different version levels.
    

Problem conclusion

  • The APAR fix optimizes the algorithm used by the Tivoli
    Monitoring Dashboard Data Provider component supporting metric
    requests to agents at different version levels.
    
    The fix for this APAR is contained in the following maintenance
    packages:
    
      | fix pack | 6.3.0-TIV-ITM-FP0007
    

Temporary fix

  • The only workaround that would not require this APAR fix to be
    applied would be to ensure that all of the Tivoli Monitoring
    agents being polled by the Hybrid Gateway are at the same
    version level within their respective application family.
