IJ51652: EVENT GUI_PMCOLLECTOR_CONNECTION_FAILED DUE TO INVALID COLLECTOR NODE IDENTIFIER

APAR status

• Closed as program error.

Error description

• Configuring perfmon --collectors with a non-cluster node name
  (e.g. the hostname which is different to the admin or daemon
  name) will fail mmsysmon noderoles detection and cause perfmon
  query port down and the GUI node will raise
  gui_pmcollector_connection_failed event.
  

Local fix

Problem summary

• Configuring perfmon --collectors with a non-cluster node name
  (e.g. the hostname which is different to the admin or daemon
  name) will fail mmsysmon noderoles detection and cause perfmon
  query port down and the GUI node will raise
  gui_pmcollector_connection_failed event.

  Benefits of the solution:
  The mmperfmon config option --collectors no longer supports
  arbitrary node names, even if they can be resolved.Only valid
  cluster node identifiers are allowed. This prevents
  unintentional missconfiguration of the Performance Monitoring
  Tool.
  
  Work Around:
  None
  
  Problem trigger:
  Use of mmperfmon config option --collectors with an invalid
  cluster node identifier.
  
  Symptom:
  Event gui_pmcollector_connection_failed on GUI node.
  
  Platforms affected:
  Linux Only
  
  Functional Area affected:
  Performance Monitoring Tool, GUI, mmhealth thresholds,
  GrafanaBridge
  
  Customer Impact:
  High Importance
  

Temporary fix
