18.104.22.168 LAN VC Channel Selection Data (Nonmanaged Objects)
The display of information about LAN VC channel selection depends on the version of OpenVMS and whether managed objects have been enabled. (For more information about managed objects, see the introduction to this chapter.)
Figure 4-22 is an example of a Nonmanaged Object LAN VC Channel Selection Data page.

22.214.171.124 LAN VC Channel Selection Data (Managed Objects Enabled)
Systems running Availability Manager with managed objects enabled collect and display the following information about LAN VC Channel Selection Data. (For more information about managed objects, see the introduction to this chapter.)
Figure 4-23 is an example of a LAN VC Channel Selection Data page with managed objects enabled.

126.96.36.199 LAN VC Closures Data
LAN VC closures data is information about the number of times a virtual circuit has closed for a particular reason. Figure 4-24 is an example of a LAN VC Closures Data page.

188.8.131.52 LAN VC Packets Discarded Data
LAN VC packets discarded data is information about the number of times packets were discarded for a particular reason. Figure 4-25 is an example of a LAN VC Packets Discarded Data page.

Before you start this chapter, be sure to read the explanations of data collection, events, thresholds, and occurrences in Chapter 1.
Figure 5-1 OpenVMS Event Pane
The Event pane helps you identify system problems. In many cases, you can apply fixes to correct these problems as well, as explained in Chapter 6.
The Availability Manager displays a warning message in the Event pane whenever
it detects a resource availability problem. If logging is enabled (the
default), the Availability Manager also logs each event in the Events Log
file, which you can display or print. (For the location of this file
and a cautionary note about it, see Section 5.2.)
5.1 Event Information Displayed in the Event Pane
The Availability Manager can display events for all nodes that are currently in communication with the Data Analyzer. When an event of a certain severity occurs, the Availability Manager adds the event to a list in the Event pane.
The length of time an event is displayed depends on the severity of the event. Less severe events are displayed for a short period of time (30 seconds); more severe events are displayed until you explicitly remove the event from the Event pane (explained in Event Pane Menu Options).
Table 5-1 provides additional information about the data items that are displayed in the Event pane.
|Node||Name of the node causing the event|
|Group||Group of the node causing the event|
|Date||Date the event occurred|
|Time||Time that an event was detected|
|Sev||Severity: a value from 0 to 100. (You can customize this value to indicate the importance of the event, with 100 as the most important.)|
|Event||Alphanumeric identifier of the type of event|
|Description||Short description of the resource availability problem|
Appendix B contains tables of events that are displayed in the Event pane. In addition, these tables contain an explanation of each event and the recommended remedial action.
When you right-click a node name or data item in the Event pane, the Availability Manager displays a shortcut menu with the following options:
|Display||Displays the Node Summary page associated with that event.|
|Remove||Removes an event from the display.|
|Freeze/Unfreeze||Freezes a value in the display until you "unfreeze" it; a snowflake icon is displayed to the left of an event that is frozen.|
|Customize||Allows you to customize events.|
During data collection, any time data meets or exceeds the threshold for an event, an occurrence counter is incremented. When the incremented value matches the value in the Occurrence box on the Event Customization page (Figure 5-2), the event is posted in the Event pane of the System Overview window (Figure 1-1).
Figure 5-2 Sample Event Customization
The sample Event Customization page indicates a threshold of 15 errors and an occurrence value of 2. This means that if the DSKERR event exceeds its threshold of 15 for two consecutive data collections, the DSKERR event is posted in the Event pane.
Note that some events are triggered when data is lower than the threshold; other events are triggered when data is higher than the threshold.
If, at any time during data collection, the data does not meet or exceed the threshold, the occurrence counter is set to zero, and the event is removed from the Event pane. Figure 5-3 depicts this sequence.
Figure 5-3 Testing for Events
When an event is posted, the following actions occur:

When an event is posted, the following actions also occur:

If you collect data on many nodes, running the Availability Manager for a long period of time can result in a large events log. For example, in a run that monitors more than 50 nodes with most of the background data collection enabled, the events log can grow by up to 30 MB per day. At this rate, systems with small disks might fill up the disk on which the events log resides.
Closing the Availability Manager application will enable you to access the events log for tasks such as archiving. Starting the Availability Manager starts a new events log.
For more detailed information about a specific event, double-click any event data item in the Event pane. The Availability Manager first displays a data page that most closely corresponds to the cause of the event. You can choose other tabs for additional detailed information.
For a description of data pages and the information they contain, see Chapter 3.
