1 Getting Started With PEEK What is PEEK? PEEK is a utility that reports the statistical information maintained by the operating system. You can use PEEK to monitor processor activity for system storage pools, paging activity, message information, send instructions, and interrupt conditions.
Running PEEK Getting Started With PEEK Running PEEK To obtain a PEEK report on a processor on your current system, enter: > PEEK This command results in the default PEEK display, which gives statistical data about three areas of a processor's activity: TIME, POOL, and PAGING statistics.

Using RUN Options Getting Started With PEEK Table 1-1. PEEK Options Option Function ALL Displays the information produced by all of the PEEK options. CME Displays relevant information related to correctable memory errors (CMEs) that have occurred since the processor was last loaded. delay Is the amount of time, in seconds, that you want PEEK to pause between samples. The range is 0 through 999. delay must be used together with samples and must appear after samples.
Specifying a Processor With the CPU Option Getting Started With PEEK Specifying a Processor With the CPU Option Unless you specify a processor, PEEK normally reports on the processor in your system that is running the TACL command interpreter or on a processor chosen by $CMON. However, you can select a different processor by using the CPU option of the RUN command. For example: > PEEK / CPU 2 / This command returns the TIME, POOL, and PAGING statistics for processor 2 on your current system.
Combining RUN Options Getting Started With PEEK 2. To use a PEEK option, enter it after the PEEK command at your TACL prompt. For example: > PEEK TIME 3. You can enter multiple PEEK options in any order on a single command line, but you must separate them from each other with either spaces or commas. For example: > PEEK TIME, CME, MESSAGES 4.

2 PEEK Syntax and Examples This section contains the following: Syntax to run PEEK with brief descriptions of each of the PEEK options Default listing formats for PEEK Detailed information about each of the PEEK options with illustrations and examples Note. Because of width constraints, some examples in this manual might not be aligned exactly as the PEEK output is. Syntax to Run PEEK The syntax of the command to run PEEK is: [ \node. ] PEEK [/ run-options /] [ option ] [ ,option ] ...
Syntax to Run PEEK PEEK Syntax and Examples OUT option if you want to send PEEK output to a file or location other than your home terminal. option is one or more of these PEEK options. Separate the options from each other with either a space or a comma. Each option is described in greater detail later in this section. If you do not enter any options, the PEEK default listing format displays information for the TIME, POOL, and PAGING options.
Syntax to Run PEEK PEEK Syntax and Examples 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).
Syntax to Run PEEK PEEK Syntax and Examples NS[AA] displays voluntary rendezvous opportunities (VRO) and inappropriate I/O buffer access counters and reintegration status. For more information, see NSAA Option on page 2-33. PA[GING] displays paging statistics. For more information, see PAGING Option on page 2-35. PO[OL] displays pool-management statistics. For more information, see POOL Option on page 2-40. TIME displays the amount of time the processor has spent on processes, interrupts, and idle time.
PEEK Default Listing Format PEEK Syntax and Examples PEEK Default Listing Format When you specify PEEK with no options, a report is produced that is equivalent to the reports displayed by the TIME, POOL, and PAGING options. Figure 2-1 on page 2-5 shows an example of the default PEEK display for systems running G-series RVUs. Figure 2-1.

TIME Option PEEK Syntax and Examples TIME Option The TIME option displays the amount of time a given processor has spent on processes, interrupts, and idle time. TIME is one of the default reports displayed when you run PEEK with no options specified.
Elements of the TIME Display PEEK Syntax and Examples Examples 1. This example displays the amount and percentage of time processor 2 has spent on processes and interrupts and the amount and percentage of idle time since the processor was last loaded: > PEEK / CPU 2 / TIME PEEK - T9050G09 - (05AUG02) SYSTEM \VIOLET COPYRIGHT TANDEM COMPUTERS INCORPORATED 1981, 1985, 1988, 1990 SYSTEM 22 FEB 2004, 16:24___ELAPSD TIME: \VIOLET 832:35:40___CPU PROCESSBUSY TIME 88:08:12.538 10.
Elements of the TIME Display PEEK Syntax and Examples IDLE TIME: Since it was last loaded, processor 2 has been idle 86.50 percent of its time. In the 10-second interval shown in Report 2, this processor has been idle 88.62 percent of its time. If this example did not specify DYNAMIC, both reports would show statistics since the processor was last loaded.

Glossary This glossary defines technical terms related to PEEK, to the internal design of the operating system, and to the system architecture for the NonStop server. active process. The process that is currently using the instruction processing unit (IPU) of a processor. Contrast with inactive process. API. See application program interface (API). application program interface (API).
clock Glossary clock. See processor clock or system clock. clock averaging algorithm. An algorithm used by the operating system to keep the processor clocks in a system synchronized. CME. (1) See correctable memory error (CME). (2) The PEEK INTERRUPTS element that reports CME interrupts. See also interrupt. complex instruction-set computing (CISC).
extensible data segment Glossary and flat segments. Extended data segments are allocated by the ALLOCATESEGMENT or SEGMENT_ALLOCATE_ Guardian procedure. extensible data segment. An extended data segment for which swap file extents are not allocated until needed. EXTPOOL. (1) A fixed-size system storage pool. (2) The PEEK POOL element that reports the size of EXTPOOL. fault address.
HP Integrity NonStop NS-series servers Glossary HP Integrity NonStop NS-series servers. The HP Integrity NonStop servers having product numbers beginning with the letters NS. These servers implement the ServerNet architecture and run the NonStop operating system. HP NonStop Blade Complex (NSBC). The set of one, two, or three NonStop Blade Elements and their associated LSUs. For the first release of Integrity NonStop servers, a NonStop Blade Complex contains one to four logical processors.
IOS Glossary IOS. I/O subsystem. Itanium Processor. The processor used in the Integrity NonStop server. Contrast with CISC processor and RISC processor. LDEV . See logical device. locked pages. The pages in a processor that are not available for swapping because they are currently assigned or are reserved for use by the operating system. logical device. (1) A process that can be accessed as if it were an I/O device; for example, the operator process is logical device LDEVOPR.
message system Glossary message system. A set of operating system procedures and data structures that handles the mechanics of exchanging messages between processes, which might be running in the same processor or different processors. millicode. The system’s lowest-level machine-dependent code, often coded in assembler language. TNS/R millicode and TNS/E millicode are functionally similar to the microcode on TNS systems.
OSS SEM Glossary OSS SEM. The table that contains all the OSS semaphores created in this processor by the semget() function. OSS SHM. The table that defines all the OSS Shared Memory segments created in this processor by the shmget() function. The term, OSS shared memory, distinguishes these segments from the Guardian shared memory segments. page fault. A reference to a logical page that is not currently in physical memory.
PPL table Glossary PPL table. A table containing process pair list (PPL) entries. See also process-pair list (PPL). prepaging. On TNS processors, a technique that involves transferring extra pages to reduce the number of reduce the number of page faults. Prepaging does not occur on TNS/R and TNS/E processors. primary path. A path enabled as the preferred path. When a primary path is disabled, an alternate (backup) path becomes the primary path. Contrast with backup path. process.
processor clock Glossary processor clock. A hardware timer on each processor that keeps processor time (the number of microseconds since system load). PTLE. See process time-list element (PTLE). ready processes. Processes that are prepared to become active. reduced instruction-set computing (RISC).
Glossary ServerNet system area network (ServerNet SAN) response to requests received from clients across a network. For example, the NonStop range of servers provides transaction processing, database access, and other services. (3) A process or program that provides services to a client or a requester.
system services Glossary system services. The tasks performed on behalf of the user or user programs by the operating system, including formatting, process control, I/O support, performance measurement, process-pair support, standard security, and transaction management. Contrast with core services. system time. The time represented by any synchronized processor clock in the system. system-load environment. The software environment that exists before the operating system is fully loaded and operational.
