HP OpenVMS Systems Documentation

This chapter describes the node data that the Availability Manager displays by default and more detailed data that you can choose to display. Node summary data is the only data displayed by default. (Differences are noted whenever information displayed for OpenVMS nodes differs from that displayed for Windows NT nodes.)

On OpenVMS systems, you can turn on and off the collection of individual types of data, and you can a specify several interval times for the collection and display of events. These are discussed in Chapter 6.

3.1 Node Panes

After you select a group of nodes in the Group pane, the Availability Manager automatically displays data for each node within that group on the Node pane of the Application window (Figure 1-3). The following sections describe the data displayed for OpenVMS and Windows NT Node panes.

3.1.1 OpenVMS Node Pane

Figure 3-1 shows an example of an OpenVMS Node pane.

Figure 3-1 OpenVMS Node Pane

Data displayed in red on your screen indicates that the amount is above the threshold set for that field.

For each OpenVMS node and group it recognizes, the Availability Manager displays the data shown in Table 3-1. The table lists the event related to each type of data; events that exceed either the default thresholds or the defaults that you set are displayed in red on the screen.

Refer to Section 6.5 for information about setting event thresholds. Appendix B describes OpenVMS and Windows NT events.

Figure 3-2 shows a sample Windows NT Node pane. From the group selected, the Availability Manager displays all the nodes with which it can communicate.

Figure 3-2 Windows NT Node Pane

For each Windows NT node in the group you select, the Availability Manager displays the data shown in Table 3-2.

The following sections describe node data pages, which you can display in either of two ways:

• Double-click a data item in the Node pane to display an associated page.
• Double-click a node name on the Node pane to display the Node Summary page (Figure 3-3). You can then click other tabs on the Node Summary page to display the same detailed data that you display by double-clicking a data item in the Node pane.

The menu bar on each node data page contains the options described in Table 3-3.

The following sections describe these node data pages:

When you double-click a node name, operating system (OS) version, or hardware model in an OpenVMS or Windows NT Node pane, the Availability Manager displays the Node Summary page (Figure 3-3).

Figure 3-3 Node Summary Page

On this page, the following information is displayed for the node selected:

By clicking the CPU tab, you can display CPU panes that contain more detailed statistics about CPU mode usage and process summaries than the Node Summary does. You can use the CPU panes to diagnose issues that CPU-intensive users or CPU bottlenecks might cause. For OpenVMS nodes, you can also display information about specific CPU processes.

When you double-click a value under the CPU or CPU Qs heading on either an OpenVMS or a Windows NT Node pane, or when you click the CPU tab, the Availability Manager displays the CPU Modes Summary in the top pane and, by default in the bottom pane, CPU Modes Detail. You can use the View menu to select the CPU Process Summary in the bottom pane (see Section 3.2.2.4).

CPU modes summaries and process summary panes are described in the following sections. Note that there are differences between the pages displayed for OpenVMS and Windows NT nodes.

3.2.2.1 Windows NT CPU Modes

Figure 3-4 shows a sample Windows NT CPU Modes page.

Figure 3-4 Windows NT CPU Modes Page

The top pane of the Windows NT CPU Modes page is a summary of Windows NT CPU usage, listed by type of mode.

On the left, the following CPU modes are listed:

• User
• Privileged
• Null

On the graph, values that exceed thresholds are displayed in red. To the right of the graph are current and extreme amounts for each mode.

Current and extreme amounts are also displayed for the following values:

• Deferred procedure calls (DPCs) queued per second
• Interrupts occurring per second

The bottom pane of the Windows NT CPU Modes contains modes details. The following data is displayed:

Figure 3-5 shows a sample OpenVMS CPU Modes summary, which is the top pane of the CPU Modes page.

Figure 3-5 OpenVMS CPU Modes Summary Pane

The CPU Modes summary pane shows OpenVMS CPU usage by type of mode. On symmetric multiprocessing (SMP) nodes, percentages are averaged across all the CPUs and are displayed as a single value.

The following table shows the alphabetic symbols that represent CPU modes:

The bars in the graph represent the percentage of CPU cycles used. Values that are lower than the thresholds are displayed in green; values that exceed thresholds are displayed in red. To the right of the graph are current and extreme amounts for each mode.

Below the graph, the Availability Manager displays the state of certain CPU process queues. The amounts displayed for COM are the sums of the queue lengths of processes in the COM and COMO states. The amounts displayed for WAIT are the sums of the queue lengths of processes in the miscellaneous WAIT, COLPG, CEF, PFW, and FPG states. (See Appendix A for explanations of CPU process states.)

3.2.2.3 OpenVMS CPU Modes Detail

The bottom pane of the CPU Modes page contains CPU modes details, as shown in Figure 3-6.

Figure 3-6 OpenVMS CPU Modes Detail Pane

In the OpenVMS CPU Modes Detail pane, the following data is displayed:

To display the OpenVMS CPU Process Summary pane at the bottom of the CPU page, select CPU Process Summary from the View menu. Figure 3-7 shows a sample OpenVMS CPU Process Summary pane.

Figure 3-7 OpenVMS CPU Process Summary Pane

The OpenVMS CPU Process Summary pane displays the following data:

When you double-click a PID on the lower part of an OpenVMS CPU Process (Figure 3-7), Memory (Figure 3-9), or I/O (Figure 3-10) page, the Availability Manager displays an OpenVMS Single Process, where you can click tabs to display specific data about one process.

This data includes a combination of data elements from the CPU Process, Memory, and I/O pages, as well as data for specific quota utilization, current image, and queue wait time. These pages are described in Section 3.2.9.

3.2.3 Memory Summaries

The Memory summary pages contain statistics about memory usage on the node you select. The Memory summary pages displayed for OpenVMS and Windows NT nodes are somewhat different, as described in the following sections.

3.2.3.1 Windows NT Memory Summary

You can display the Windows NT Memory in either of the following ways:

• Double-click a node, and then click the Memory tab.
• Double-click a value under the MEM heading.

The Availability Manager then displays the Windows NT Memory page (Figure 3-8).

Figure 3-8 Windows NT Memory Page

The Current and Extreme amounts on the page display the data shown in the following table. The table also indicates what the graph amounts represent.

When you double-click a value under the MEM heading in an OpenVMS Node pane, or if you click the Memory tab, the Availability Manager displays the OpenVMS Memory page (Figure 3-9).

Figure 3-9 OpenVMS Memory Page

The graph in the top pane shows memory distribution (Free, Used, Modified, Bad) as absolute values, in megabytes of memory. Current and extreme values are also listed for each type of memory distribution. (Free memory uses the lowest seen value as its extreme.)

The bottom pane displays the following data:

When you double-click a PID on the lower part of an OpenVMS CPU Process (Figure 3-7), Memory (Figure 3-9), or I/O (Figure 3-10) page, the Availability Manager displays an OpenVMS Single Process, where you can click tabs to display specific data about one process. This data includes a combination of data from the CPU Process, Memory, and I/O pages, as well as data for specific quota utilization, current image, and queue wait time. These pages are described in Section 3.2.9.
