HELP Option
HELP Option
The HELP option displays a syntax summary of all PEEK options. The G09 product
version of the PEEK HELP appears as:
> PEEK HELP
PEEK/CPU n/ [PAging] - displays paging statistics (default)
[POols] - displays system pool statistics (default)
[INIT] - init pools to current value/zero (super grp)
[MESsages] - displays message sending statistics
[MQCinfo] - shows MQC utilization stats
[INTerrupts]- displays interrupt routine statistics
[TIME] - shows cpu utilization statistics ONLY
[CME] - displays CME statistics ONLY
[ALL] - PAGING, POOLS, IO, MES, EXP, INT, TIME, and CME
[<samples>] - number of time to display data
[<delay>] - interval in seconds between samples
[Dynamic] - shows current activity in each display
INIT Option (Super Group Only)
Use the INIT option to reset the maximums of certain POOL elements to equal the
values in the CURRENT columns in the PEEK POOL report.
These POOL elements are reset:

Time-list elements (TLEs)

Process control blocks (PCBs)

Process time-list elements (PTLEs)

POSIX mapping entry elements (PMEs)

OSS Shared Memory Resource (SHM)

OSS Semaphores (SEM)

EXTPOOL entries

SYSPOOL entries

MAPPOOL entries
Consideration
Use INIT only when you want to initialize (and thus destroy the past history of) pool-
related maximums. Specify the DYNAMIC option instead of INIT when you want to
monitor processor activity for a relatively short time period (15 minutes or less). For
example, if you run PEEK daily and want a record of each day's activity only, run PEEK
when activity is low and specify INIT. Later, run PEEK and specify DYNAMIC to
preserve the daily maximums. This technique can help you monitor processor activity
where the level of use fluctuates greatly.
If you use DYNAMIC with INIT, the first report displays the reset values. Subsequent
reports display activity since the values were reset.
