Chapter 3
Getting Information About Nodes

Note

Before you start this chapter, be sure to read the explanation of data collection, events, thresholds, and occurrences in Chapter 1. HP also recommends completing the getting-started steps described in Chapter 2.

Node summary data is the only data that is collected by default. The Availability Manager looks for events only in data that is being collected.

You can collect additional data in either of the following ways:

  • Opening any display page that contains node-specific data (for example, CPU, memory, I/O) automatically starts foreground data collection and event analysis except for Lock Contention and Cluster Summary information. (You must select these tabs individually to start foreground data collection.) Collection and evaluation continue as long as a page with node-specific data is displayed.
  • Clicking a check mark on the Data Collection Customization page (which you can select on the Customize OpenVMS menu) enables background collection of that type of data. Data is collected and events are analyzed continuously until you remove the check mark.

See Chapter 1 and Chapter 7 for details.

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

Although Cluster Summary is one of the tabs displayed on the OpenVMS Node Summary page (see Figure 3-4), see Chapter 4 for a detailed discussion of OpenVMS Cluster data.

Note

On many node displays, you can hold the cursor over a data field or column header to display an explanation of that field or header in a little rectangle, called a tooltip. Figure 3-2 contains an example.

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 in the Node pane of the Application window (Figure 3-1).

Figure 3-1 OpenVMS Node Pane


Recall that the colors of the icons represent the following states:

Color Description
Brown Attempts to configure the node have failed---for example, because it failed the security check.
Yellow Node security check is in progress or has failed.
Black Path to node has been lost.
Red Security check was successful. However, a threshold has been exceeded, and an event has been posted.
Green Security check was successful; data is being collected.

The following sections describe the data displayed for OpenVMS and Windows Node panes.

3.1.1 OpenVMS Node Pane

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 described in Table 3-1. This table also lists the abbreviation of the event that is related to each type of data, where applicable. See Section 7.6 for information about setting event thresholds. Appendix B describes OpenVMS and Windows events.

Note that you can sort the order in which data is displayed in the Node Pane by clicking a column header. To reverse the sort order of a column of data, click the column header again.

Table 3-1 OpenVMS Node Data
Data Description of Data Related Event

1By default, the CPU heading follows Node Name on a line of Node Pane data. You can use the cursor to move a column heading to another location on the line, if you like.

By holding the cursor over many column headers and some data items on Availability Manager screens, you can display a tooltip. Figure 3-2 is an example of a tooltip that explains the CPU Queues column header in the Node Pane.

Figure 3-2 Sample Tooltip


3.1.2 Windows Node Pane

Figure 3-3 is an example of a Windows Node pane. From the group you select, the Availability Manager displays all the nodes with which it can communicate.

Figure 3-3 Windows Node Pane


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

Table 3-2 Windows Node Data
Data Description
Node Name Name of the node being monitored.
CPU Percentage of CPU usage of all the processes on the node.
MEM Percentage of memory that is in use.
DIO Direct I/O usage of processes on the node.
Processes Number of processes on the node.
Threads Number of threads on the node. A thread is a basic executable entity that can execute instructions in a processor.
Events The number of events on the node. An event is used when two or more threads want to synchronize execution.
Semaphores The number of semaphores on the node. Threads use semaphores to control access to data structures that they share with other threads.
Mutexes The number of mutexes on the node. Threads use mutexes to ensure that only one thread executes a section of code at a time.

3.2 Node Data Pages

The following sections describe node data pages, which you can display in any of the following 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 3-4). 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.
  • Double-click an event in the Event pane.

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

Table 3-3 Node Data Page Menu Bar
Menu Option Description For More Information
File Contains the Close option, which you can choose to exit from the pages. n/a
View Contains options that allow you to view data from another perspective. See specific pages.

Customize Contains options that allow you to organize data collection and analysis and to display data by filtering and customizing Availability Manager data. Chapter 7

The following sections describe individual node data pages.

3.2.1 Node Summary

When you double-click a node name, operating system (OS) version, or hardware model in an OpenVMS or Windows Node pane, the Availability Manager displays the Node Summary page (Figure 3-4).

Figure 3-4 Node Summary Page


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

Data Description
Model System hardware model name.
OS Version Name and version of the operating system.
Uptime Time (in days, hours, minutes, and seconds) since the last reboot.
Memory Total amount of physical memory (in megabytes) found on the system.
Active CPUs Number of CPUs running on the node.
Configured CPUs Number of CPUs that are configured to run on the node.
Max RADs Maximum number of resource affinity domains (RADs) for this node.
Serial Number The system's hardware serial number retrieved from the Hardware Restart Parameter Block (HWRPB).
Galaxy ID The Galaxy ID uniquely identifies a Galaxy. Instances in the same Galaxy have the same Galaxy ID.

3.2.2 CPU Modes and Process Summaries

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 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 nodes.

3.2.2.1 Windows CPU Modes

Figure 3-5 contains a sample Windows CPU Modes page.

Figure 3-5 Windows CPU Modes Page


The top pane of the Windows CPU Modes page is a summary of Windows 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 that occurred per second

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

Data Description
CPU ID Decimal value representing the identity of a processor in a multiprocessing system. On a uniprocessor, this value is always CPU #00.
Mode % Graphical representation of the percentage of active modes on that CPU. The color displayed matches the mode color on the graph on the top pane.
DPCs Queued Rate that deferred procedure call (DPC) objects are queued to this processor's DPC queue.
DPC Rate Average rate that DPC objects are queued to this processor's DPC queue per clock tick.
DPC Bypasses Rate that dispatch interrupts were short-circuited.
APC Bypasses Rate that kernel asynchronous procedure call (APC) interrupts were short-circuited.

3.2.2.2 OpenVMS CPU Modes Summary and Process States

Figure 3-6 shows sample OpenVMS CPU Modes summary and CPU Process States, which are the left and right top panes of the CPU Modes page.

Figure 3-6 OpenVMS CPU Modes Summary and Process States Pane


CPU Modes Summary

In the CPU modes section of the pane, percentages are averaged across all the CPUs and are displayed as a single value on symmetric multiprocessing (SMP) nodes.

To the left of the graph is a list of CPU modes. The bars in the graph represent the percentage of CPU cycles used for each mode. 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 percentages of time spent in each mode.

Below the graph, the Availability Manager displays the COM and WAIT process queues:

  • COM: The value displayed is the number of processes in the COM and COMO states.
  • WAIT: The value displayed is the number of processes in the miscellaneous WAIT, COLPG, CEF, PFW, and FPG states.

CPU Process States

The right side of Figure 3-6 shows a sample CPU Process States display.

Appendix A contains explanations of the CPU process states. Note that the value for MWAIT, in the left column, is the sum of all values for the states in the two right columns.

3.2.2.3 OpenVMS CPU Modes Detail

The bottom pane of the CPU Modes page contains CPU modes details, as shown in Figure 3-7.

Figure 3-7 OpenVMS CPU Modes Detail Pane


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

Data Description
CPU ID Decimal value representing the identity of a processor in a multiprocessing system. On a uniprocessor, this value is always CPU #00.
State One of the following CPU states: Boot, Booted, Init, Rejected, Reserved, Run, Stopped, Stopping, or Timeout.
Mode % Graphical representation of the percentage of active modes on that CPU. The color displayed coincides with the mode color in the graph in the top pane.
PID Process identifier (PID) value of the process that is using the CPU. If the PID is unknown to the console application, the internal PID (IPID) is listed.
Process Name Name of the process active on the CPU. If no active process is found on the CPU, the name is listed as *** None ***.
Capabilities One or more of the following CPU capabilities: Primary, Quorum, Run, or Vector.
RAD Number of the RAD where the CPU exists.
