The customization levels for various Availability Manager values are displayed as icons on some pages. The OpenVMS Data Collection Customization page (Figure 7-1) displays several of these icons.

Figure 7-1 OpenVMS Data Collection Customization

The icons preceding each data item in Figure 7-1 indicate the current customization level for each collection choice. Table 7-2 describes these icons and tells where each appears in Figure 7-1.

Table 7-2 Customization Icons in Figure 7-1

Icon	Location	Meaning
Graph	Before "Disk volume"	Current setting is from the built-in AM Defaults.
Magnifying glass	Bottom left of window	Current setting is from the Application level.
Swoosh	Before "Disk status"	Current setting has been modified at the OpenVMS Operating System Level.
Double monitors	Before "Cluster summary"	Current setting has been modified at the group level.
Single monitor	Before "Memory"	Current setting has been modified at the node level.

7.1.2 Setting Levels of Customization

When you customize values, the Availability Manager keeps track of the next higher level of each value. This means that you can reset a value to the value set at the next higher level.

To return to the values set at the preceding level, click the Use default values button at the top of a customization page. The icon on the "Use default values" button and explanation at the bottom of the page indicate the previous customization level.

In the main System Overview window (see Figure 2-1), you can select the customization levels that are shown in Table 7-1. The following sections explain levels of customization in more detail.

7.1.3 Knowing the Number of Nodes Affected by Each Customization Level

Another way of looking at Availability Manager customization is to consider the number of nodes affected by each level of customization. Depending on which customization menu you use and your choice of menu items, your customizations can affect one or more nodes, as indicated in the following table.

Nodes Affected	Action
All nodes	Select Customize Application... on the menu shown in Figure 7-2.
All Windows nodes	Select Operating Systems --> Customize Windows NT... on the menu shown in Figure 7-2.
All OpenVMS nodes	Select Operating Systems --> Customize OpenVMS... on the menu shown in Figure 7-2.
Nodes in a group	Select Customize... on the shortcut menu shown in Figure 7-7. The customization options you choose affect only the group of nodes that you select.
One node	Select Customize... on the shortcut menu shown in Figure 7-8 or on the Customize shortcut menu on the Node page. The customization options you choose affect only the node that you select.

7.2 Customizing Settings at the Application and Operating System Levels

In the System Overview window menu bar, select Customize. The Availability Manager displays the shortcut menu shown in Figure 7-2.

Figure 7-2 Application and Operating System Customization Menu

When you select Customize Application..., by default the Availability Manager displays the Group/Nodes Lists page (Figure 7-3), where the Inclusion lists tab is the default.

On the Groups/Nodes Inclusion page (Figure 7-3) you can select groups of nodes or individual nodes to be displayed.

Figure 7-3 Application Settings---Groups/Nodes Inclusion

On the Groups/Nodes Inclusion page, you have the following choices:

• Group List
  Select the Group List check box. Then enter the names of the groups of nodes you want to monitor. (The names are case-sensitive, so be sure to enter the correct case.)
  For instructions on changing the group membership of a node, see Section 7.4.1 and Section 7.4.2
• Node List
  Select the Node List check box. Then enter the names of individual nodes you want to monitor. (The names are case-sensitive, so be sure to enter the correct case.)
• Both Group List and Node List
  If you select both check boxes, you can enter the names of groups of nodes as well as individual nodes you want to monitor. (If you enter the name of an individual node, the Availability Manager displays the name of the group that the node is in, but no additional nodes in that group.)
• Neither list
  The Group List and Node List are not used; all groups and all nodes are monitored.

If you decide to return to the default (Group List: DECAMDS) or to enter names again, select Use default values.

After you enter a list of nodes or groups of nodes, click one of the following buttons at the bottom of the page:

Option	Description
OK	Accepts the choice of names you have entered and exits the page.
Cancel	Cancels the choice of names and does not exit the page.
Apply	Accepts the choice of names you have entered but does not exit the page.

If nodes were previously selected for monitoring, their names are not removed from the display even if you click OK or Apply. They are filtered out the next time the Availability Manager is started.

7.2.1.2 Application Settings---Groups/Nodes Exclusion Lists

As an alternative to the Inclusion lists on the Groups/Nodes Inclusion page, you can click the Exclusion lists tab in Figure 7-4, where you can select groups of nodes or individual nodes to be excluded from display.

Figure 7-4 Application Settings---Groups/Nodes Exclusion Lists

On the Groups/Nodes Exclusion Lists page, you have the following choices:

• Group List
  Select the Group List check box. Then enter the names of the groups of nodes you want to exclude from monitoring. (The names are case-sensitive, so be sure to enter the correct case.)
  For instructions on changing the group membership of a node, see Section 7.4.1 and Section 7.4.2.
• Node List
  Select the Node List check box. Then enter the names of individual nodes you want to exclude from monitoring. (The names are case-sensitive, so be sure to enter the correct case.)
• Both Group List and Node List
  If you select both check boxes, you can enter the names of groups of nodes as well as individual nodes you want to exclude from monitoring. (If you enter the name of an individual node, the Availability Manager displays the name of the group that the node is in, but no additional nodes in that group.)
• Neither box
  The Group List and Node List are not used; all groups and all nodes are monitored.

After you enter a list of nodes or groups of nodes, click one of the buttons at the bottom of the page:

Option	Description
OK	Accepts the choice of names you have entered and exits the page.
Cancel	Cancels the choice of names and does not exit the page.
Apply	Accepts the choice of names you have entered but does not exit the page.

If nodes were previously selected for monitoring, their names are not removed from the display even if you click OK or Apply to exclude them from monitoring.

7.2.2 Customizing Windows Operating System Settings

When you select Customize Windows NT..., the Availability Manager displays a page similar to the one shown in Figure 7-5.

Figure 7-5 Windows Operating System Customization

The default page displayed is the Event Customization page. Instructions for using this page are in Section 7.8.1. The other tabs displayed are the Event Escalation page, which is explained in Section 7.7, and the Windows Security Customization page, which is explained in Section 7.9.2.2.

7.2.3 Customizing OpenVMS Operating System Settings

When you select Customize OpenVMS..., the Availability Manager displays the page shown in Figure 7-6, which contains tabs for the last 6 types of customization listed in Table 7-1. (Instructions for making these types of customizations are later in this chapter, beginning in Section 7.5.)

Figure 7-6 OpenVMS Operating System Customization

To perform customizations at the group level, right-click a group name in the System Overview window. The Availability Manager displays a small menu similar to the one shown in Figure 7-7.

Figure 7-7 Group Customization Menu

When you select Customize, the Availability Manager displays a page similar to the one shown in Figure 7-6.

7.4 Customizing Settings at the Node Level

To customize a specific node, do either of the following:

• Select the Customize option at the top of the Group/Node page.
• Right-click a node name in the Node pane of the System Overview window (see Figure 2-1).
  The Availability Manager displays the shortcut menu shown in Figure 7-8.

Figure 7-8 Node Customization Menu

When you select Customize, the Availability Manager displays a customization page similar to the one shown in Figure 7-6.

7.4.1 Changing the Group of an OpenVMS Node

Each Availability Manager Data Collector node is assigned to the DECAMDS group by default.

You need to edit a logical on each Data Collector node to change the group for that node. To do this, follow these steps:

1. Assign a unique name of up to 15 alphanumeric characters to the AMDS$GROUP_NAME logical name in the AMDS$AM_SYSTEM:AMDS$LOGICALS.COM file. For example:

   $ AMDS$DEF AMDS$GROUP_NAME FINANCE ! Group FINANCE; OpenVMS Cluster alias

2. Apply the logical name by restarting the Data Collector:

   $ @SYS$STARTUP:AMDS$STARTUP RESTART

You need to edit the Registry to change the group of a Windows node. To edit the Registry, follow these steps:

1. Click the Windows Start button. On the menu displayed, first select Programs, then Accessories, and then Command Prompt.
2. Type REGEDIT after the angle prompt (>).
   The system displays a screen for the Registry Editor, with a list of entries under My Computer.
3. On the list displayed, expand th HKEY_LOCAL_MACHINE entry.
4. Double-click SYSTEM.
5. Click CurrentControlSet.
6. Click Services.
7. Click damdrvr.
8. Click Parameters.
9. Double-click Group Name. Then type a new group name of 15 alphanumeric characters or fewer, and click OK to make the change.
10. On the Control Panel, select Services, and then select Stop for "PerfServ."
11. Again on the Control Panel, select Devices, and then select Stop for "damdrvr."
12. First restart damdrvr under "Devices," and then restart PerfServ under "Services."
    This step completes the change of groups for this node.

When you choose the Customize OpenVMS menu option in the System Overview window (see Figure 7-2), by default the Availability Manager displays the OpenVMS Data Collection Customization page (Figure 7-9) where you can select types of data you want to collect for all of the OpenVMS nodes you are currently monitoring. You can also change the default Availability Manager intervals at which data is collected or updated.

Figure 7-9 OpenVMS Data Collection Customization

Table 7-3 identifies the page on which each type of data collected and displayed in Figure 7-9 appears and indicates whether or not background data collection is turned on for that type of data collection. See Chapter 1 for information about background data collection. (You can also customize data collection at the group and node levels, as explained in Section 7.1.)

Table 7-3 Data Collection Choices

Data Collected	Background Data Collection Default	Page Where Data Is Displayed
Cluster summary	No	Cluster Summary page
CPU mode	No	CPU Modes Summary page
CPU summary	No	CPU Process States page
Disk status	No	Disk Status Summary page
Disk volume	No	Disk Volume Summary page
I/O data	No	I/O Summary page
Lock contention	No	Lock Contention page
Memory	No	Memory Summary page
Node summary	Yes	Node pane, Node Summary page, and the top pane of the CPU, Memory, and I/O pages
Page/Swap file	No	I/O Page Faults page
Single disk	Yes 1	Single Disk Summary page
Single process	Yes 2	Data collection for the Process Information page

You can choose additional types of background data collection by selecting the Collect check box for each one on the Data Collection Customization page of the Customize OpenVMS... menu (Figure 7-6). A check mark indicates that data is to be collected at the intervals described in Table 7-4.

Table 7-4 Data Collection Intervals

Interval Name	Description
Display	How often the data is collected when its corresponding display is active.
Event	How often the data is collected when its corresponding display is not active and when events are active.
NoEvent	How often the data is collected when its corresponding display is not active and when events are not active.

You can enter a different collection interval by selecting a row of data and selecting a value. Then delete the old value and enter a new one.

If you change your mind and decide to return to the default collection interval, select one or more rows of data items: then select Use default values. The system displays the default values for all the collection intervals.

When you finish customizing your data collection, click one of the following buttons at the bottom of the page:

Option	Description
OK	To confirm any changes you have made and exit the page.
Cancel	To cancel any changes you have made and exit the page.
Apply	To confirm and apply any changes you have made and not exit the page.

7.6 Customizing OpenVMS Data Filters

When you choose "Customize" at the operating system, group, or node level and then select the Filter tab, the Availability Manager displays pages that allow you to customize data (see Figure 7-10). The types of data filters available are the following:

• CPU
• Disk Status
• Disk Volume
• I/O
• Lock Contention
• Memory
• Page/Swap File

Filters can vary depending on the type of data collected. For example, filters might be process states or a variety of rates and counts. The following sections describe data filters that are available for various types of data collection.

You can also customize filters at the group and node levels (see Section 7.1).

Keep in mind that the customizations that you make at the various levels override the ones set at the previous level (see Table 7-1). The icons preceding each data item (see Table 7-2) indicate the level at which the data item was customized. In Figure 7-10, for example, the icon preceding "CPU" indicates that the current setting comes from the AM Defaults.

If you change your mind and decide to return to filter values set at the previous level, select Use default values. The icon appearing on the button indicates the level of the previous values. In Figure 7-10, for example, the previous value is the AM Defaults value.

When you finish modifying filters on a page, click one of the following buttons at the bottom of the page:

Option	Description
OK	To confirm any changes you have made and exit the page.
Cancel	To cancel any changes you have made and exit the page.
Apply	To confirm and apply any changes you have made and continue to display the page.
