IV87239: UNIX OS AGENT DOES NOT COMPUTE CORRECTLY THE QUEUE DEPTH AND SIZE

APAR status

• Closed as Permanent restriction.

Error description

• Unix OS Agent - UX - does not compute correctly the queue depth
  and size metrics for UNXPRINTQ attribute group.
  Affected Platforms / Versions: All platforms and all releases
  Diagnostics:
  The UX agent issues the following command to gather print queue
  data:
  LANG=C /bin/enq -isAW 2>/dev/null
  .
  To debug issues with what appear to be invalid metrics for
  UNIXPRINTQ
  attributes when comparing to external "enq" or "lpstat"
  commands, gather
  following RAS1 tracing and refresh workspace to drive data
  collection:
  .
  In the "ux.ini" file set:
  KBB_RAS1=ERROR (UNIT: KRA ALL) (UNIT: KUX12 ALL) (UNIT: lpstat
  ALL)
  .
  Get export of the TEP workspace showing invalid data, as well as
  gathering
  "enq" command from same timeframe as UX agent tracing
  externally:
  LANG=C /bin/enq -isAW 2>/tmp/printqueue.out
  .
  Identify the printer / queue that appears to have invalid data
  by comparing the
  external "enq" command output vs. what is displayed in TEP
  workspace.
  .
  In the RAS1 logging for the UX agent, review the tracing for
  this printer / queue:
