Measure Reference Manual

WRITE-BUSY-TIME
(Legacy Style only) Time spent writing to the disk. This counter measures the time from the instruction
that starts the write operation to the interrupt that ends the operation. This counter includes the time
spent writing data and positioning the disk heads to write the data.
Counter type: Busy.
Usage Notes for All OPDISK Entities
• OPDISK does not measure optical disk volumes that have had no activity even if the REPORT
ZERO-REPORTS attribute is set to INCLUDE.
• SUBSYSTEM-VERSION for ZMSODISK records are reported as zero.
• OPDISK reports include fields that are calculated from OPDISK counters. These fields are not
defined in the OPDISK DDL record:
DEVICE-AST
(ZMS Style only) The average time that each request spends waiting or being processed
by DP2. DEVICE-QBUSY-TIME is divided by the sum of READS and WRITES.
Counter type: Service time.
OSSCPU
The OSSCPU entity provides information about the Open System Services elements that operate
in each processor of a system, including:
• POSIX extended segment (PXS)
• OSS file system cache
• File manager
• Pipe pool
• Pipe server
• Local Server 2 (LS2) for AF_UNIX Sockets
OSSCPU entities can only be used on systems running Measure G10 and later PVUs.
