10 Managing Alarms

This chapter describes how you can use the Oracle Communications Service Broker Netra 6000 High Availability Manager (HA Manager) Administration Console to view the notifications that Runtime MBeans generate.

About Alarms

The HA Manager provides a graphical user interface to view JMX notifications, known as alarms. Alarms report changes to the following components:

HA Manager software, such as crossing the upper threshold that you specified for a counter attribute of a Runtime MBean. See "About HA Manager Software Alarms" for more information.
The hardware of an HA Manager deployment, such as adding a new hardware component. See "About HA Manager Deployment Hardware Alarms" for more information.

Each alarm provides the following information:

The HA Manager component, such as a Managed Server or a slot in which an alarm occurred
The object name of the Runtime MBean that generated the notification
The time when the notification was generated
The notification message

Note:

You must configure the HA Manager notification mechanism to view alarms. For more information about configuring software notifications, see the Understanding Notifications section in the Monitoring Service Broker chapter in the Oracle Communications Service Broker System Administration Guide.

About HA Manager Software Alarms

The Administration Console enables you to view alarms that report on the following events:

A software Runtime MBean generated a notification on crossing the upper threshold
A software Runtime MBean generated a notification on crossing the lower threshold
A software Runtime MBean cleared a notification on crossing the upper threshold
A software Runtime MBean cleared a notification on crossing the lower threshold

About HA Manager Deployment Hardware Alarms

The Administration Console enables you to view alarms that report the following events:

A hardware Runtime MBean generated a notification about adding a hardware component to HA Manager.
A hardware Runtime MBean generated a notification about removing a hardware component from HA Manager.
A hardware Runtime MBean generated a notification about changing the availability status of a hardware component.
A hardware Runtime MBean generated a notification about changing the operational status of a hardware component.
A hardware Runtime MBean generated a notification about system errors.

About the Alarms Window

Figure 10-1 shows the Alarms window that enable you to view and manage alarms.

Figure 10-1 Alarms Window

Table 10-1 describes the fields displayed in the Alarms window.

Table 10-1 Alarm Window Fields

Field	Description
Filter	Enables you to enter criteria to limit the results displayed. See "Searching Alarms" for more information.
Host	Specifies the component on which an alarm occurred: For software alarms, the Host field displays the name of a Managed Server on which an alarm occurred For hardware alarms, the Host field displays the number of the blade slot on which an alarm occurred
Source	Specifies the object name of the Runtime MBean that generated a notification
Time	Specifies the time when the notification was generated
Description	Displays a notification message

Searching Alarms

Depending on how you configured the notifications mechanism, the Alarms window can contain a significant number of alarms. To help you find specific alarms, HA Manager provides the following capabilities:

Filtering Alarms
Sorting Alarms

Filtering Alarms

You can narrow the list of alarms displayed in the Alarms window by specifying text that the alarms must include. For example, if you want to view only those alarms that were generated by a particular Runtime MBean, you can specify the object name of this Runtime MBean. HA Manager searches for this text in all fields and displays the alarms that contain the specified text at least in one of the fields.

The filter is not case-sensitive.

To filter alarms:

Click the Alarms tab.

The Alarms window appears.
In the Filter text field, enter text to search for.

Every time you modify the text in the Filter field (for example, enter or delete a character), HA Manager refreshes the list of alarms and displays only those alarms that contain the specified text.

Note:

Filtering alarms changes only change the view of alarms on a local computer. Filtering does not have any impact on how Runtime MBeans generate notifications or how HA Manager processes these notifications.

Sorting Alarms

You can sort alarms displayed in the Alarms window by any of the fields that appear on the window. For example, if you want to find all alarms generated by a specific Runtime MBean, you can sort alarms using the Source field. In this case, all alarms are displayed according to their object name in alphabetic order. Similarly, you can sort alarms according to the time they were generated.

By default, alarms are sorted at the time they were received by HA Manager.

To resort alarms:

Click the Alarms tab.

The Alarms window appears.
Select the header of a column in which you want to sort the alarms.

Alarms are sorted accordingly.

Clearing the List of Alarms

You can clear the list of alarms if the list contains a significant number of alarms that are irrelevant to you.

This action cannot be undone.

To clear the list of alarms:

Click the Alarms tab.

The Alarms window appears.
Click Clear.

HA Manager deletes all alarms from the Alarms window.

Configuring the Alarms Display

HA Manager updates the Alarms window periodically with these newly generated notifications. The MBean notifications are stored permanently. HA Manager displays the newer alarms at the top of the Alarms window.

You can specify how frequently HA Manager refreshes the list of alarms.

In addition, you can define the maximum number of alarms to be displayed. If the number of generated alarms exceeds your maximum number, the older alarms are removed from the list.

To configure alarms display:

Click the Alarms tab.

The Alarms window appears.
In the Alarms window, click Settings.

The Settings dialog box appears.
Select one of the following Refresh speed options:
- Slow: Every 3 seconds
- Normal: Every 1.5 seconds
- Fast: Every 0.5 second
In the Buffer Size text field, specify the number of alarms to display.
Click OK.
