1 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 VBS (VAX Only) 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 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. 2 CONVERT The CONVERT command converts a pre-Version 5.0 MONITOR recording file to the current format. Format CONVERT file-spec 3 Parameter file-spec Specifies the file to be converted. The default file specification is MONITOR.DAT. 3 Qualifiers /OUTPUT The file specification of the converted file. The default specification is MONITOR.DAT. 2 EXECUTE The EXECUTE command or the at sign (@) executes a series of MONITOR commands contained in a file. Format EXECUTE (@) file-spec 3 Parameter file-spec Specifies a command file to be executed by the EXECUTE (@) command. 3 Qualifiers None. 2 EXIT The EXIT command terminates MONITOR, returning control to command level. Format EXIT 3 Parameters None. 3 Qualifiers None. 2 HELP The HELP command displays information about MONITOR. Format HELP [command] 3 Parameter command Specifies the name of a MONITOR command for which HELP is desired. 3 Qualifiers None. 3 Example MONITOR> HELP MONITOR INITIALIZE The INITIALIZE command reestablishes initial default settings for parameters and qualifiers previously altered by the SET DEFAULT command. The command in this example requests help information about the INITIALIZE command. 2 INITIALIZE The INITIALIZE command reestablishes initial default settings for parameters and qualifiers 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 [/command qualifier[,...]] classname[,...] [/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 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 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 online help topic DCL_Tips (subtopic Date_Time). /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 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. /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. /DISPLAY /DISPLAY[=file-spec] (default) /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 online help topic DCL_Tips (subtopic Date_Time). /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. /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. /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 to be collected.

If you specify an existing file but omit the version number, a new version of the file is created. /SUMMARY /SUMMARY[=file-spec] /NOSUMMARY (default) Specifies that an ASCII disk file be created containing summary statistics on all data collected for this request. If the optional file specification is omitted, it defaults to MONITOR.SUM. /VIEWING_TIME /VIEWING_TIME=seconds Specifies the duration for each screen image display for /DISPLAY requests.
