## Modifying the Monitor Parameters

To modify the monitor parameters:

1. Select an instance of the System Administration > Monitor Management > Monitor in the object workspace.

2. Invoke the context menu and choose Open Parameters.

   The monitor parameter settings are displayed.

3. The parameters are explained below. You can change their settings as desired.

4. Choose OK to save your changes.

#### Main Task Parameters

Parameter | Explanation
--- | ---
Monitor Node | The node under which Entire Output Management is running.
Minimum Wait | The minimum time (in seconds) the Monitor is to wait between two consecutive monitoring cycles. You can modify this value by entering a new value.
Maximum Wait | The maximum time (in seconds) the Monitor is to wait between two consecutive monitoring cycles. You can modify this value by entering a new value.
Wait Increment | The number of seconds by which the wait time increases. If there is no activity during the minimum wait time, the wait time is increased by this value, until the maximum is reached. When activity occurs, the wait time returns to the minimum. You can modify this value by entering a new value.
Current Wait | The wait time in effect for the current cycle (in seconds).

See also Wait Factor under Monitor Defaults.

## Displaying the Monitor Parameters

To display the monitor parameters:

1. Select an instance of the System Administration > Monitor Management > Monitor node in the object workspace.

2. Invoke the context menu and choose Display.

3. The monitor parameters are displayed. They are described under Main Task Parameters.

4. Select Cancel to close the window.

## Starting the Monitor

To start the Monitor, the Entire System Server node specified for start must be active.

To start the Monitor:

1. Select an instance of the System Administration > Monitor Management > Monitor node in the object workspace.

2. Invoke the context menu and choose Start.

   A message confirms the start, and the Monitor status changes accordingly.

   The corresponding console messages will be displayed:

       NOM1510 Monitor initialization completed successfully.
       NOM1603 Monitor NOMXTS dbid fnr on node node started.

## Waking the Monitor

To activate the Monitor before the next scheduled activity cycle, see Wait parameters under Main Task Parameters.

To wake the Monitor:

1. Select an instance of the System Administration > Monitor Management > Monitor node in the object workspace.

2. Invoke the context menu and choose Wake.

If there was any pending work, the Monitor status changes. When the activity cycle is completed, the Monitor status changes back to "Idle".

## Closing the Monitor

To close the Monitor:

1. Select an instance of the System Administration > Monitor Management > Monitor node in the object workspace.

2. Invoke the context menu and choose Close.

The Monitor status changes to "Shutdown In Progress". This means that the Monitor has not yet detected the close, since it is in wait status. The next time it is active, the Monitor detects the close and performs the normal close. The status then changes to "Closed".

The corresponding console message will be displayed:

    NOM1515 Monitor shutdown completed.

## Displaying the Monitor Status

To display the status of the monitor:

1. Select an instance of the System Administration > Monitor Management > Monitor node in the object workspace.

2. Invoke the context menu and choose Status.

   The status of the Monitor is displayed. The possible values are listed under Monitor Status.

## Displaying the Monitor Log

To display the monitor log:

1. Select an instance of the System Administration > Monitor Management > Monitor node in the object workspace.

2. To list all events, proceed directly with the next step.

   To list selected events, first invoke the context menu and choose Filter Log. A window is displayed in which you specify your selection criteria, and choose OK

3. Invoke the context menu and choose Display Log.

   The monitor log is displayed.

   You can sort the log entries by date (ascending or descending).

## Purging the Monitor Buffer Pool

To purge the monitor buffer pool:

1. Select an instance of the System Administration > Monitor Management > Monitor node in the object workspace.

2. Invoke the context menu and choose Purge Buffer.

   All entries in the Natural Buffer Pool are purged.

## Purging a Single Buffer Pool Entry

To purge a single buffer pool entry:

1. Select an instance of the System Administration > Monitor Management > Monitor node in the object workspace.

2. Invoke the context menu and choose Purge Single.

3. Enter data for the object to be purged and select OK.

   The object specified is purged from the Monitor Buffer Pool.
