HELPLIB.HLB  —  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 VSI 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.
