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
Date_Time).
2 /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.
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.
4 /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.
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).
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 /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.
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.
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
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 VSI OpenVMS System
Manager's Manual describes remote monitoring.
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.
11 /RECORD
/RECORD[=file-spec]
/NORECORD (default)
Specifies that a binary disk file be created containing all
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.
12 /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.
13 /VIEWING_TIME
/VIEWING_TIME=seconds
Specifies the duration for each screen image display for /DISPLAY
requests. Values can range from 1 to 9,999,999.
