Controlling Threshold Management at the Global Level
This section explains how to control resource monitoring, the timing of
operation cycles, and how to display information in a variety of ways
with Threshold Manager. Specifically, you learn to:
* turn on and off the display of notifications, which are messages
that Threshold Manager sends to the system console
* display configuration information on screen as a list or
graphically
* print a list of configuration information
* turn on and off monitoring of individual resources
* reset the configuration to the initial values
* change the time interval between Threshold Manager's operation
cycles
* use Threshold Manager with OpenView System Manager
To control global notifications
You use two Threshold Manager commands, ENABLENOTIFY and DISABLENOTIFY,
to control the display of global notifications on the system console.
ENABLENOTIFY displays information and DISABLENOTIFY prevents the display
of information about system resource usage.
You can enter either command at the Threshold Manager prompt or from a
job. There are no parameters for the commands.
* To enable global notifications, at the Thmgr: prompt enter
ENABLENOTIFY or type EN.
* To disable global notifications, at the Thmgr: prompt enter
DISABLENOTIFY or type DN.
Using these commands does not affect the configuration of an individual
resource. You must set notification to YES for a resource with the
MODIFYTHRESHOLD command to see information about that resource. Or, to
suppress information about some, but not all, resources, use the
MODIFYTHRESHOLD command to disable notification for the individual
resources that you want to ignore. (For more information, read "To
Modify a Threshold" later in this chapter.)
To display the configuration
You can display information about the Threshold Manager configuration as
a list or graphically.
* To display a complete list of configuration information, at the
Thmgr: prompt enter SHOW (or type SH).
* To display the configuration for an individual resource, enter the
SHOW command followed by the name of the resource you want to
view. For example, to display the configuration for the
File_Extents resource, at the Thmgr: prompt enter:
Thmgr: SHOW File_Extents
* To see a graphic display of the configuration, at the Thmgr:
prompt enter DISPLAY (or type DP). The display remains on the
screen until you type EXIT (or E).
NOTE You can only use the DISPLAY command interactively; you cannot
issue the command from a job.
To print the configuration display
Instead of displaying the configuration on screen, you can print a list
of configuration information. To do so, you redirect the output to a
file and then print it by following these steps:
1. At the MPE prompt, create a file equation by entering:
:FILE THMGROUT;REC=-80,,F,ASCII;DISC=5000
2. Type RUN THMGR.PUB.SYS to access the Threshold Manager.
3. At the Thmgr: prompt, type the SHOW command.
4. Type EXIT to exit Threshold Manager.
5. Print the THMGROUT file
To enable monitoring of a resource
Use the ENABLERESOURCE command to turn on monitoring of a resource. Once
you enable monitoring, Threshold Manager monitors the thresholds
associated with the resource and, depending upon how it is configured,
displays messages on the console and/or controls job and session logons.
You can issue the ENABLERESOURCE command at the Thmgr: prompt or from a
job. The syntax of the command is:
ENABLERESOURCE (ER) [RESOURCE=]{ResourceName}
The only parameter, ResourceName, must be any of the resources listed
when you issue the SHOW command. For example, to enable monitoring of
the resource Timers, at the Thmgr: prompt enter:
Thmgr: ENABLERESOURCE Timers
To disable monitoring of a resource
Use the DISABLERESOURCE command to turn off monitoring of a resource.
Once you disable monitoring, Threshold Manager no longer monitors the
thresholds associated with the resource and does not display messages on
the console or control job and session logons.
You can issue the DISABLERESOURCE command at the Threshold Manager prompt
or from a job. The syntax of the command is:
DISABLERESOURCE (DR) [RESOURCE=]{ResourceName}
The only parameter, ResourceName, must be any of the resources listed
when you issue the SHOW command. For example, to disable monitoring of
the IO_Requests resource, at the Thmgr: prompt enter:
Thmgr: DISABLERESOURCE IO_Requests
Once you have disabled monitoring of a resource, the global configuration
display shows the resource name with a D (for disabled) in the left
column; all other columns for that resource remain empty.
NOTE DISABLERESOURCE is one of three commands that you can use to
disable monitoring with Threshold Manager. Each one works at a
different level. You can disable Threshold Manager at the global
level (DISABLEMANAGER), at the resource level (with this command,
DISABLERESOURCE), and at the threshold level (DELETETHRESHOLD).
To reset the configuration
Use the RESET command to overwrite all changes to the configuration file
and restore it to the preset factory values. This command lets you
return to a known starting point when you need to create a customized
configuration that best suits your site.
You can issue this command at the Threshold Manager prompt or from a job.
To reset the configuration, at the Thmgr: prompt, enter RESET or type
RS.
To modify the time interval of the operation cycle
Use the MODIFYINTERVAL command to change the time interval between
Threshold Manager's operation cycles.
The syntax for the MODIFYINTERVAL command is:
MODIFYINTERVAL (MI) [INTERVAL=]{intervaltime}
The interval is an integer representing the number of seconds between
cycles. You can enter any value between 25 and 3600 seconds. If you
modify the interval when the factory-provided (default) configuration is
active, Threshold Manager does not save the value when you reboot.
For example, to change the time interval from 120 seconds to 60 seconds,
at the Thmgr: prompt enter:
Thmgr: MODIFYINTERVAL 60
To monitor Threshold Manager with OpenView System Manager
HP OpenView System Manager is an HP OpenView Windows application that
provides a single integrated console to manage multiple HP 3000 computers
in a network.
HP OpenView System Manager is shipped with a sample systems oriented map,
configured for one system, which can be used as a starting point for
customizing your systems oriented operation's environment. The task map
contains an icon labelled MPE/iX. By default, you manage Threshold
Manager through this icon.
We recommend that you create a customized icon for Threshold Manager.
This will allow you to monitor Threshold Manager notifications without
the clutter created by messages from other applications and peripherals
monitored through the MPE/iX icon. To create a customized icon for
Threshold Manager, please refer to HP OpenView System Manager Manager's
Guide (36936-61002). In chapter 1, Introduction to HP OpenView System
Manager, you will find a list of icons available for customization.
Chapter 1 also contains information on customizing your OpenView
environment. You will need the Threshold Manager identification number
for HP OpenView System Manager, which is 216, to customize an icon.
NOTE For detailed information on how to use OpenView System Manager,
please refer to HP OpenView System Manager Manager's Guide
