Syntax to Run PEEK
D[YNAMIC]
must be used in combination with samples. The first sample displays
information about a processor’s activity since the processor was loaded. If you
specify DYNAMIC, successive samples display only the activity that occurs
during each sample interval.
Specify DYNAMIC instead of INIT when you want to monitor processor activity
for a relatively short time period (15 minutes or less). DYNAMIC preserves the
measured maximums that are listed in each PEEK report.
HELP
displays a syntax summary of all PEEK options.
INIT (Super group (255,*) only)
resets the values for pool elements that are stored by PEEK. When you specify
INIT, PEEK resets all pool maximums to equal the values in the CURRENT
columns in the PEEK report. INIT also resets the MAXIMUM USED values for
time-list element (TLE) entries and the process control block (PCB) entries to
the CURRENT USED values.
Use INIT only when you want to initialize (and thus destroy the past history of)
pool-related maximums stored by PEEK. Specify DYNAMIC instead of INIT
when you want to monitor processor activity for a relatively short time period
(15 minutes or less).
INT[ERRUPTS]
displays a count of software interrupts by type. For more information, see
INTERRUPTS Option on page 2-21.
MES[SAGES]
displays the number of unsequenced packets, control pa
ckets, and data
messages sent by the processor and provides statistical data about the
processor’s message quick cells (MQCs). For more information, see
MESSAGES Option on page 2-25.
MQC[INFO]
displays information on the message quick cells (MQCs). Message quick cells
are data structures that the message system uses for interprocess
communication. The system automatically builds and allocates MQCs as it
needs them. MQCs serve a purpose similar to link control blocks (LCBs) and
extended memory link control blocks (XLIs), which were used in earlier RVUs.
