1  MONITOR
   The Monitor utility (MONITOR) is a system management tool used
   to obtain information on 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 class-name
   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
      VBS (VAX Only)

   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 command MONITOR.

   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 collected by MONITOR is normally 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 command MONITOR 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.

   for parameters and qualifiers previously altered by the SET
   DEFAULT command.

   Format

     INITIALIZE
 

3  Parameters

   None.
 

3  Qualifiers

   None.
 

2  MONITOR

   The MONITOR command initiates monitoring of statistics for the
   classes of information you specify.

   Format

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

3  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 class-name 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 OpenVMS DCL Dictionary, 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.
 

3  Command_Qualifier_Descriptions
 

/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 DCL Help topic SPECIFY.
 

/BY_NODE

      /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 is used only to display 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.
 

/COMMENT

      /COMMENT=string
      /NOCOMMENT

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

/DISPLAY

      /DISPLAY[=file-spec]
      /NODISPLAY

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

/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 DCL Help topic SPECIFY.
 

/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 of 1 through 9,999. The default interval is
   300 seconds.
 

/INPUT

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

   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.
 

/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.
 

/NODE

      /NODE=(nodename,...)

   Specifies the nodes (up to 48 in a cluster) for which data is

   names with commas, and enclose the list in parentheses.

   Remote monitoring in an OpenVMS Cluster environment may not
   be compatible between 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

   OpenVMS Alpha and  Yes                No
   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 OpenVMS System Manager's
   Manual describes remote monitoring.
 

/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.
 

/RECORD

   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.
 

/SUMMARY

      /SUMMARY[=file-spec]
      /NOSUMMARY

   Specifies that an ASCII disk file be created containing
   summary statistics on all data collected for this request.
