Collection Services data files: QAPMBUS

Support for a particular bus as well as what metrics are supported for that bus is dependent on the type of bus, how that bus connects to the system, and if assigned to the partition.

Historically, records were produced for all PCI buses even though data was instrumented only for bus usage within the collecting partition. For that situation now, data is captured only for those buses that have had activity within the collecting partition.

For newer technologies, the hardware may provide additional instrumentation. Hardware metrics represent bus usage by all partitions. Consequently, the collecting partition must be authorized to obtain this data (reference the "Allow performance information collection" option within the HMC partition configuration). If the collecting partition is authorized, buses that support hardware metrics are reported independent of partition assignments.

Field Name	Description	Attribute
INTNUM	Interval number: The nth sample database interval based on the start time specified in the Create Performance Data (CRTPFRDTA) command.	PD (5,0)
DTETIM	Interval date (yymmdd) and time (hhmmss): The date and time of the sample interval.	C (12)
INTSEC	Elapsed interval seconds: The number of seconds since the last sample interval.	PD (7,0)
BUIOPB	System bus number. Bus numbering begins with one. Before V4R5, bus numbering began at zero.	PD (5,0)
BUOPSR	Number of OPSTARTs received: RRCB in server storage.	PD (11,0)
BUSGLR	Signals received.	PD (11,0)
BUOPSS	Number of OPSTARTs sent.	PD (11,0)
BUSGLS	Signals sent.	PD (11,0)
BURSTQ	Restart queues sent.	PD (11,0)
BUBNAR	Occurrences of BNA received.	PD (11,0)
BUTPKT	Total packets (sent or received).	PD (11,0)
BUKBYO	Kilobytes DMAed out.	PD (11,0)
BUKBYI	Kilobytes DMAed in.	PD (11,0)
BUNOSR	Normal flow OPSTARTs received.	PD (11,0)
BUNRDR	Reserved.	PD (11,0)
BUORQS	OPSTART requests sent.	PD (11,0)
BUTIMO	Reserved.	PD (11,0)
BUBNAS	Reserved.	PD (11,0)
BUQSAS	Queue space available sent.	PD (11,0)
BUTYPE	Bus type. Supported values include: 'S' = SPD Bus (no longer supported) 'P' = PCI bus 'V' = Virtual bus	C (1)
BUCAT	Bus category. This field indicates if this bus record has some special characteristics, which may require a special interpretation of its performance data. Each bit in this field has an independent meaning: X'00' = no special category applies X'01' = this bus is attached to an I/O hub X'02'= This record represents a switch. The data reported is the sum of all buses under the switch. The bus number reported is the first bus under the switch.	BINCHAR (1)
BUHUB	Hub number. If this bus is associated with an I/O hub, this is the number of that hub. Note: an I/O hub may be imbedded in the backplane	B (9,0)
BUMAXRATE	Maximum byte rate. When available from hardware, this is the estimated maximum rate that data may be both sent and received in bytes per second through the hardware port.	B (18,0)
BUCBSND	Command bytes sent. When available from hardware, this is the number of command bytes sent through the hardware port.	B (18,0)
BUDBSND	Data bytes sent. When available from hardware, this is the number of data bytes sent through the hardware port.	B (18,0)
BUCBRCV	Command bytes received. When available from hardware, this is the number of command bytes received through the hardware port.	B (18,0)
BUDBRCV	Data bytes received. When available from hardware, this is the number of data bytes received through the hardware port.	B (18,0)
