VMS Help SHOW, CLUSTER *Conan The Librarian (sorry for the slow response - running on an old VAX) |
Invokes the Show Cluster utility to monitor and display cluster activity and performance. For more information about the Show Cluster utility, refer to the OpenVMS System Management Utilities Reference Manual or online help. Format SHOW CLUSTER If you specify the command without any qualifiers, SHOW CLUSTER displays a single cluster report and then returns control to the DCL level. To invoke a continuous SHOW CLUSTER display, enter the following command: $ SHOW CLUSTER/CONTINUOUS SHOW CLUSTER requires no special privileges because it is installed with the CMKRNL privilege. In a continuous display, you can control report output with SHOW CLUSTER commands. For information about the SHOW CLUSTER commands, invoke a continuous SHOW CLUSTER display and type HELP at the Command> prompt.
1 - Qualifiers |
1.1 - /BEGINNING
/BEGINNING=time Specifies the time that the SHOW CLUSTER session is to begin. You can specify absolute time, a delta time, or a combination of the two. Observe the syntax rules for time values described in the OpenVMS User's Manual or the online help topic DCL_Tips (subtopic Date_Time). If you specify a future time, your process is placed in a state of hibernation until the specified time. Use this qualifier with the /OUTPUT and /ENDING qualifiers to run SHOW CLUSTER without direct user intervention. You can specify time as absolute time expressed as [dd-mmm-yyyy[:]] [hh:mm:ss.cc], or a delta time expressed as [dddd-][hh:mm:ss.cc], or a combination of the two. Observe the syntax rules for time values described in the OpenVMS User's Manual or the online help topic DCL_Tips (subtopic Date_Time).
1.2 - /CONTINUOUS
Specifies a continuously updating display. If you omit the qualifier, SHOW CLUSTER produces a single display and returns control to the DCL command level. Running SHOW CLUSTER in the continuous mode allows you to use SHOW CLUSTER commands to control the display. In a continuous display, you can control report output with SHOW CLUSTER commands. For information about the SHOW CLUSTER commands, invoke a continuous SHOW CLUSTER display and type HELP at the Command> prompt. SHOW CLUSTER has commands that allow you to customize the display. You can add and remove fields and classes, rearrange the position of windows, scroll their contents, or create an initialization or command procedure that can recreate a particular window setup. To exit from a continuous display and return to the DCL level, type the EXIT command or press Ctrl/Z. To exit from SHOW CLUSTER without erasing the screen, press Ctrl/C. To interrupt SHOW CLUSTER, press Ctrl/Y. For a complete description of the Show Cluster utility and commands, refer to the OpenVMS System Manager's Manual for overview information and the OpenVMS System Management Utilities Reference Manual for reference information.
1.3 - /ENDING
/ENDING=time Specifies the time that the SHOW CLUSTER session is to end. You can specify an absolute time, a delta time, or a combination of the two. Observe the syntax rules for time values described in the OpenVMS User's Manual or the online help topic DCL_Tips (subtopic Date_Time). Use this qualifier with the /BEGINNING and /OUTPUT qualifiers to run SHOW CLUSTER without direct user intervention. You can specify time as absolute time expressed as [dd-mmm- yyyy[:]][hh:mm:ss.cc], or a delta time expressed as [dddd- ][hh:mm:s.cc], or a combination of the two. Observe the syntax rules for time values described in the OpenVMS User's Manual or the online help topic DCL_Tips (subtopic Date_Time).
1.4 - /INTERVAL
/INTERVAL=seconds Specifies the number of seconds that display information remains on the screen before it is updated. By default, the interval time is 15 seconds. If you use an initialization file in noncontinuous mode and the initialization file contains a SET SCREEN command that changes the screen size, SHOW CLUSTER sets the screen to the specified size for one update interval and then sets the screen to the original size.
1.5 - /OUTPUT
/OUTPUT=filespec Directs the output from SHOW CLUSTER to the specified file instead of the current SYS$OUTPUT device. SHOW CLUSTER output is always in printable file format, regardless of the file or device type specified. Output can be up to 132 columns wide and can be sent to any file, terminal, or print device. You can also direct output to a file with the WRITE command. The filespec is the name of the file or device to which SHOW CLUSTER output is directed. The default file name is SHOW_ CLUSTER.LIS. You can direct output to a device other than SYS$OUTPUT, by specifying a valid device name.
