Collection Services data files: QAPMDISKRB
This database file includes disk file response bucket entries and contains one record for each device resource name. It is intended to be used in conjunction with the QAPMDISK file.
This file reports separate response bucket entries for read operations and for write operations. The response times and service times are reported in microseconds. The associated disk response time boundaries (in microseconds) are reported in the QAPMCONF file in GKEY fields G1-GA.
| 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) |
| DSDRN | Device resource name. Typically, there is one disk (device) resource per disk unit except for a multipath disk unit that has multiple disk resources associated with it. | C (10) |
| DSRBKCTR1 | Disk read operations in disk response time bucket 1. Number of read operations since last sample, the response time of which was less than the first disk response time boundary. | B (9, 0) |
| DSRBKRTR1 | Disk response time in disk read response time bucket 1. Combined response time of all disk read operations since last sample, the response time of which was less than the first disk response time boundary (microseconds). | B (18, 0) |
| DSRBKSTR1 | Disk service time in disk read response time bucket 1. Combined service time of all disk read operations since last sample, the response time of which was less than the first disk response time boundary (microseconds). | B (18, 0) |
DSRBKCTRnn
DSRBKRTRnn DSRBKSTRnn |
Disk read operations, disk response time and disk service time are repeated for a total of 11 counter sets per record. | |
| DSRBKCTW1 | Disk write operations in disk response time bucket 1. Number of disk write operations since last sample, the response time of which was less than the first disk response time boundary. | B (9, 0) |
| DSRBKRTW1 | Disk response time in disk write response time bucket 1. Combined response time of all disk write operations since last sample, the response time of which was less than the first disk response time boundary (microseconds). | B (18, 0) |
| DSRBKSTW1 | Disk service time in disk write response time bucket 1. Combined service time of all disk write operations since last sample, the response time of which was less than the first disk response time boundary (in microseconds). | B (18, 0) |
DSRBKCTWnn
DSRBKRTWnn DSRBKSTWnn |
Disk write operations, disk response time and disk service time are repeated for a total of 11 counter sets per record. |
