Performing System Management Tasks

Getting Started with Threshold Manager 

This section teaches you how to access the Threshold Manager utility and
display the Thmgr:  prompt.  You learn how to enable (turn on) and
disable (turn off) threshold management.  This section includes a sample
global configuration display that is similar to what you see on your
system console.  Finally, you learn how to exit the Threshold Manager
utility.

To access Threshold Manager 

Before you can enable or disable threshold management, or execute any of
the other Threshold Manager commands available to you, you must access
the Threshold Manager utility.  To do so, enter the following command at
the MPE prompt:

     :RUN THMGR.PUB.SYS 

You will see the following prompt:

     Thmgr:

You can enter any of the Threshold Manager commands at the Thmgr:
prompt.  For an overview of the commands, read "Using Threshold Manager
Commands" later in this chapter.

To enable Threshold Manager 

To turn on (enable) Threshold Manager, enter the following command at the
Thmgr:  prompt:

     Thmgr: ENABLEMANAGER 

If this is the first time you have enabled Threshold Manager, it uses the
default configuration installed at the factory.  If not, and you have
made any configuration changes while Threshold Manager was disabled, they
will now take effect.

To study resource usage on your system, enter the following command at
the Thmgr:  prompt:

     Thmgr: SHOW 

Read the CV% column in the global configuration display.  An example of
this display appears on the next page, with the figure callouts described
on the page that follows.


NOTE  If you prefer, you can also observe current resource usage as a
      graph by entering the DISPLAY command at the Threshold Manager
      prompt.  To see resource usage as a graph, Threshold Manager must
      be enabled.



          Figure 7-1.  Threshold Manager Global Configuration Display 

The numbered elements of the Threshold Manager Global Configuration
Display shown on the previous page are described below.

   1.  Indicates if Threshold Manager is enabled or disabled.

   2.  Indicates if notifications are enabled or disabled at the global
       level.

   3.  Indicates the time elapsed (in seconds) between each Threshold
       Manager operating cycle.

   4.  Indicates if monitoring of an individual resource is enabled or
       disabled.

   5.  Indicates the names of the resources monitored by Threshold
       Manager.

   6.  Indicates the current consumption of a resource.  The current
       value is indicated as a percentage (%) of the total resource.  It
       takes one time interval to refresh the current value.  When
       Threshold Manager is initially enabled, zeroes appear in this
       column until the first operating cycle is complete.

   7.  Indicates the level at which the first (or only) threshold has
       been set.  The value is indicated as a percentage (%) of the total
       resource.

   8.  An X in this column indicates a notification has been set for a
       specific resource at this threshold level.

   9.  Indicates the level at which the second threshold (if present),
       has been set.  The value is indicated as a percentage (%) of the
       total resource.

  10.  An X in this column indicates a notification has been set for a
       specific resource at this second threshold level.

  11.  An X in this column indicates if a control has been set for a
       specific resource at this second threshold level.

To disable Threshold Manager 

Use the DISABLEMANAGER command to turn off, or disable, threshold
management on your system.  Once you execute this command, the effects of
the controls that have been executed are reversed or nullified, the
system no longer monitors resources and returns to its normal state.

To turn off Threshold Manager, at the Thmgr:  prompt enter:

     Thmgr: DISABLEMANAGER 

To exit Threshold Manager 

To exit Threshold Manager, enter the following command at the Thmgr:
prompt:

     Thmgr: EXIT 

You will see the MPE prompt displayed on the screen.

This command does not stop the Threshold Manager program.  If Threshold
Manager is active, it will remain active after you issue the EXIT
command.
