Error description

• APAR Type:            Field
  Approver Initials:    GDC
  Severity:             2
  Reported Release:     621
  Compid:               5724C040W
  ABSTRACT:             Windows OS Agent returns strange huge
                        values for some attribute groups.
  .
  PROBLEM DESCRIPTION:
  
  The following attributes may overflow returning
  2147483647, when perfmon does not return the correct data:
  .
  NT_Process Attribute Group
  .
  - IO Data Bytes per Sec
  - IO Data Operations per Sec
  - IO Other Bytes per Sec
  - IO Other Operations per Sec
  - IO Read Bytes per Sec
  - IO Read Operations per Sec
  - IO Write Bytes per Sec
  - IO Write Operations per Sec
  .
  NT_LOGICAL_DISK Attribute Group
  .
  - pctdskrdtm - %_Disk_Read_Time - counter: % Disk Read Time
  - pctdsktime - %_Disk_Time - counter: % Disk Time
  - pctdskwrtm - %_Disk_Write_Time - counter: % Disk Write Time
  - dskpctfrsp - Avg_Disk_ms/Read - counter: Avg. Disk sec/Read
  - dskbtssec - Disk_Bytes/Sec - counter: Disk Bytes/sec
  - dskquelen - Disk_Queue_Length - counter: Current Disk Queue
  Length
  - dskrdbtsec - Disk_Read_Bytes/Sec - counter: Disk Read
  Bytes/sec
  - dskrdsec - Disk_Reads/Sec - counter: Disk Reads/sec
  - dsktrnssec - Disk_Transfers/Sec - counter: Disk Transfers/sec
  - dskwrtsec - Disk_Writes/Sec - counter: Disk Writes/sec
  - dskwrtbyts -  Disk_Write_Bytes/Sec - counter: Disk Write
  Bytes/sec
  - freemgbtes - Free_Megabytes - counter: Free Megabytes
  - pcfree - %_Free - counter: % Free Space
  - avgqlen -  Avg_Disk_Queue_Length - counter: Avg. Disk Queue
  Length
  - avgrdqlen - Avg_Disk_Read_Queue_Length - counter: Avg. Disk
  Read Queue Length
  - avgwrqlen - Avg_Disk_Write_Queue_Length - counter: Avg. Disk
  Write Queue Length
  - dskbtssec8 - Disk_Bytes/Sec_64 - counter: Disk Bytes/sec
  - dskrdbtse8 - Disk_Read_Bytes/Sec_64 - counter: Disk Read
  Bytes/sec
  - dskwrtbyt8 - Disk_Write_Bytes/Sec_64 - counter: Disk Write
  Bytes/sec
  .
  .
  The following two attributes do not have a corresponding
  counter:
  .
  totalsize & pcused
  .
  pcused is calculated based on pcfree, and could therefore
  provide wrong data as well.
  .
  When the above values are not correct, Microsoft perfmon tool
  returns a blank value for the corresponding counters.
  .
  RECREATE INSTRUCTIONS:
  Random

Problem conclusion

• The following attributes display value "unavailable" (-1)
  instead of returning
  2147483647, when perfmon does not return the correct data for
  the following data:

  .
  - IO Data Bytes per Sec
  - IO Data Operations per Sec
  - IO Other Bytes per Sec
  - IO Other Operations per Sec
  - IO Read Bytes per Sec
  - IO Read Operations per Sec
  - IO Write Bytes per Sec
