IT31024: DEGRADED DATA COLLECTION STATUS.

APAR status

• Closed as program error.

Error description

• Storage Insights data collection status is shown as
  degraded.
  Performance monitor job logs show the following kind
  of messaging:
  
  Performance data could not be collected for
  device <device_name> (0000000000000000). The current samples
  are skipped. (HWNPM4304E The request for performance data could
  not be retrieved from the queue by the data collector, probably
  this one is down or encountered problems connecting to the
  server.)
  
  
  Internally, the
  traceDataCollectorManager_errors_x.log files will show the
  following exception:
  
  [CollThread7]
  [CollectorTaskManager.waitOnTask] [ERROR] Request for processID
  xxxxxxx was not retrieved by collector before queue timeout 60
