Measure Reference Manual

INTR-BUSY-TIME
Time that the CPU spent executing interrupt handlers. Most interrupts are caused by the processing
of messages and I/O operations. The appropriate system description manual describes each type
of interrupt.
For TNS/E systems, this is the total time spend executing system Interrupt Processes (IPs) and system
Auxiliary Processes (APs).
Counter type: Busy.
IPU
(ZMS Style only) For NSMA systems in Measure J01 and later PVUs, IPU-specific counters. This
field is divided into three subfields:
Counter TypeDescriptionSubfield
BusyTime during which this IPU was busy.IPU-BUSY-TIME
IncrementingNumber of dispatches for this IPU.IPU-DISPATCHES
QueueTime (in microseconds) that processes spent on the ready
list. Same as CPU-QTIME but for an IPU.
IPU-QTIME
LINK-LARGE-MSGS
Number of messages transferred to a CPU that exceeded the readlinkcache message size.
Counter type: Incrementing.
LINK-PREPUSH-MSGS
Number of messages transferred to another CPU using the prepush protocol.
Counter type: Incrementing.
LINK-READLINK-MSGS
Number of messages transferred to another CPU not using the prepush protocol but within the
readlinkcache message size.
Counter type: Incrementing.
LOCKED-PAGES-END
(ZMS Style only) In Measure H06/J04 and later PVUs, the number of page frames that were locked
in main memory at the end of the measurement interval. The value is an aggregate value for all
processes running in the CPU.
This counter is valid and displayed by MEASCOM in ZMS style when the CPU subsystem version
(ZMSCPU.HDR.SUBSYSTEM-VERSION), supplied by NonStop OS, is three or greater; otherwise
the counter contains a zero value and is not displayed by MEASCOM.
Counter type: Snapshot.
LOCKED-PAGES-QTIME
(ZMS Style only) Reserved for future use.
LOCKED-PAGES-START
(ZMS Style only) In Measure H06/J04 and later PVUs, the number of page frames that were locked
in main memory at the start of the measurement interval. The value is an aggregate value for all
processes running in the CPU.
