VMS Help  —  MONITOR
    The Monitor utility (MONITOR) is a system management tool used
    to obtain information about operating system performance. MONITOR
    allows you to monitor classes of systemwide performance data
    (such as system I/O statistics, page management statistics,
    and time spent in each of the processor modes) at specifiable
    intervals, and produce several types of output.

    To monitor a particular class of information, specify the class
    names corresponding to the information classes that you want to
    monitor. For example, to monitor page management statistics,
    specify the PAGE class name in the MONITOR command. MONITOR
    collects system performance data by class and produces the
    following three forms of optional output:

    o  A disk recording file in binary format

    o  Statistical terminal displays

    o  A disk file containing statistical summary information in
       ASCII format

    The utility initiates a single MONITOR request for the classes of
    performance data specified each time you enter a command in the
    following form:

    MONITOR [/qualifier[,...]] classname[,...] [/qualifier[,...]]

    Regardless of the order in which you specify classname
    parameters, MONITOR always executes requests in the following
    sequence:

       PROCESSES
       STATES
       MODES
       PAGE
       IO
       FCP
       LOCK
       DECNET
       FILE_SYSTEM_CACHE
       DISK
       DLOCK
       SCS
       SYSTEM
       CLUSTER
       RMS
       MSCP_SERVER
       TRANSACTION
       VECTOR
       TIMER
       RLOCK

    Depending on the command qualifiers specified, MONITOR collects
    system performance data from the running system or plays back
    data recorded previously in a recording file. When you play back
    data, you can display it, summarize it, and even rerecord it to
    reduce the amount of data in the recording file.

    To invoke MONITOR, enter the DCL command MONITOR.

    $ MONITOR

    The utility then displays the following prompt:

    MONITOR>

    To begin monitoring a system, issue the Monitor utility MONITOR
    command.

                                   NOTE

       If you attempt to monitor a remote node that is
       incompatible, the system displays the following message:

       %MONITOR-E-SRVMISMATCH, MONITOR server on remote node is an incompatible
                               version

       If you receive this message, contact your HP support
       representative for a remedial kit that corrects this
       problem.

       Before you install the remedial kit, you can still use
       MONITOR to obtain data about the remote node. To do this,
       record the data on the remote node, and then run the MONITOR
       playback feature to examine the data on the local node.

    Generally, each MONITOR request runs until the time specified or
    implied by the /ENDING qualifier. To exit from MONITOR, enter the
    EXIT command at the MONITOR> prompt or press Ctrl/Z. To terminate
    a MONITOR request without exiting from the utility, press Ctrl/C.

    Information that MONITOR collect is usually displayed as ASCII
    screen images. You can use the optional /DISPLAY qualifier to
    specify a disk file to contain the information. If you omit the
    file specification, output is directed to SYS$OUTPUT. See the
    Monitor utility MONITOR command for a discussion of the /DISPLAY
    qualifier.

    You can also initiate MONITOR requests from command level by
    entering the DCL command MONITOR with the desired qualifiers and
    parameters. However, in terms of conserving system resources, it
    is preferable to initiate requests in response to the MONITOR>
    prompt.

               qualifier[,...]]

7.1  –  Parameter

 classname[,...]

    Specifies the class of performance data to be monitored. To
    monitor all classes, specify the ALL_CLASSES parameter. When you
    specify several classes, separate the classname parameters with
    commas or plus signs. You cannot specify the CLUSTER class name
    with any other class name. Cluster monitoring functions require
    that DECnet for OpenVMS be installed.

    The MONITOR and SET DEFAULT commands accept the same qualifiers.
    As these qualifiers follow the standard rules of DCL grammar as
    specified in the <REFERENCE>(VMS_DCLDICT_REF), you can abbreviate
    any qualifier or keyword as long as the abbreviation is not
    ambiguous. Use the asterisk and the percent sign as wildcard
    characters unless otherwise noted.

7.2  –  Command Qualifier Descriptions

7.2.1    /BEGINNING

       /BEGINNING=time

    Specifies the time that monitoring begins, by using a combination
    of absolute and delta times. Observe the syntax rules for time
    values described in the online help topic DCL_Tips (subtopic

       /BY_NODE
       /NOBY_NODE

    Specifies that performance class data in a multifile summary be
    displayed as a single column of AVERAGE statistics for each node.

    The /BY_NODE qualifier displays data in a multifile summary. If
    you specify only one input file, MONITOR ignores the /BY_NODE
    qualifier because you are not performing a multifile summary.

7.2.3    /COMMENT

       /COMMENT=string
       /NOCOMMENT (default)

    Specifies an ASCII string to be stored in the output recording
    file. The string can contain up to 60 characters.

7.2.4    /DISPLAY

       /DISPLAY[=file-spec] (default)

    Specifies whether information collected by MONITOR is to be
    displayed as ASCII screen images. Optionally names the disk file
    to contain the output.

7.2.5    /ENDING

       /ENDING=time

    Specifies the time that monitoring ends, by using a combination
    of absolute and delta times. Observe the syntax rules for time
    values described in the online help topic DCL_Tips (subtopic
    Date_Time).

7.2.6    /FLUSH_INTERVAL

       /FLUSH_INTERVAL=seconds

    Specifies the interval, in seconds, at which data collected by
    MONITOR (contents of MONITOR buffers) is written to disk. Values
    must be in the range from 1 to 9,999. The default interval is 300
    seconds.

7.2.7    /INPUT

       /INPUT[=(file-spec,...)]
       /NOINPUT (default)

    Controls whether performance data is played back from one or more
    input files or collected from the running system. If you specify
    more than one file, enclose the list in parentheses, and separate
    the file specifications with commas. Wildcard characters are
    allowed in the file specification.

7.2.8    /INTERVAL

       /INTERVAL=seconds

    Specifies the sampling interval between data collection events,
    recording events, and display events. Values can range from 1 to
    9,999,999.

7.2.9    /NODE

       /NODE=(nodename,...)

    Specifies the nodes (up to 48 in a cluster) for which data is
    to be collected. If you specify more than one name, separate the
    names with commas, and enclose the list in parentheses.

    Remote monitoring in an OpenVMS Cluster environment might not be
    compatible for nodes that are running different OpenVMS versions.
    The following table shows the compatibility of versions for
    remote monitoring.

                       OpenVMS Alpha and  OpenVMS Alpha Version 1.5
                       VAX Version 6.n    and VAX Version 5.n

    VAX Version 6.n

    OpenVMS Alpha      No                 Yes
    Version 1.5 and
    VAX Version 5.n

    To obtain data from an incompatible remote node, record the data
    on the remote node and then use the MONITOR playback feature to
    examine the data on the local node. The <REFERENCE>(VMS_SYSMAN_
    MAN) describes remote monitoring.

7.2.10    /OUTPUT

       /OUTPUT=file-spec

    Used with the CONVERT command, this qualifier specifies the name
    of the converted recording file. The default specification is
    MONITOR.DAT. File lists are not permitted.

    collected data for the request. Note that recording is restricted
    to files on disks. No wildcard characters are allowed in the file
    specification. If you omit the file type, the default file type
    is .DAT. If you omit the file specification, output is generated
    to a file named MONITOR.DAT in the current default device and
    directory. If you specify an existing file but omit the version
    number, a new version of the file is created.

7.2.12    /SUMMARY

       /SUMMARY[=file-spec]

    in the system.

    In a multifile summary request, the classes CLUSTER and PROCESSES
    are ignored. If these classes are the only classes specified on
    the command line, MONITOR does not recognize them and displays a
    "no classes specified" error message.

    Beginning in OpenVMS Version 8.3, four new qualifiers (
    /TOPKERNEL, /TOPEXECUTIVE, /TOPSUPERVISOR, and /TOPUSER) allow
    you to monitor per-process-based modes usage. These qualifiers
    are useful in helping to identify the top consumers of the
    various CPU modes. For example, if the MONITOR MODES command
    reveals that an excessive amount of supervisor mode is being
    used, the new MONITOR PROCESSES/TOPSUPERVISOR display reveals
    which process-and therefore, which user-is responsible.

    display showed only a maximum of 8 processes on one screen. In
    OpenVMS Version 7.3 and later versions, the choice of which one
    of three screens is displayed is determined by the number of CPUs
    on the system. (See the examples in the MONITOR chapter in the
    hardcopy <REFERENCE>(vms_sysman_util_ref).)
