Collection services data files: QAPMBUSINT
This file contains data for internal system buses.
The metrics supported are dependent on the instrumentation within the hardware chips. Support for a particular bus is dependent on both the type of bus as well as the chip family.
There may be one or more records each interval for a reported bus. The number of records as well as the metrics supported are dependent on both bus type and chip type.
These metrics are
instrumented in the hardware and represent bus usage by all partitions.
The
collecting partition must be authorized to obtain this data (reference
the "Allow performance information collection" option within the HMC
partition configuration).
| 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) |
| DATETIME | Interval date and time. The date and time of the sample interval. | Timestamp |
| INTSEC | Elapsed interval seconds. The number of seconds since the last sample interval. | PD (7, 0) |
| BUNBR | Bus number. The hardware assigned number associated
with the bus or hub. |
B (9, 0) |
| BUTYPE | Bus type. Supported bus types are:
