Common Views

vFoglight makes use of common views in most of the standard dashboards. Using common views in pre-declared dashboards is an effective way to enable and create easy workflows. Examples of views used in most of the dashboards include the Alarm list display and the Host summary display.

Alarm List

When a list of alarms is shown, the same alarm list view appears as a popup or fixed path depending on the navigation path.

Figure 7

The Alarm list view displays a summary of alarms by severity level at the top. The counts in the title are for outstanding alarms. The Outstanding Alarms view shows

Ack’ed and Cleared columns containing a Y (Yes) or N (No) to indicate the

Acknowledgement status. While the Alarms list also shows cleared alarms, the cleared alarms are not included in the count for outstanding alarms. Cleared alarms appears dimmed out. Cleared alarms can be filtered out. You can also apply a filter to the alarm

list using other criteria, as described in “ Filtering the Alarms View ” on page 62.

Managing Alarms

You can select an individual alarm and once selected, choose to take action on the alarm that has been fired such as Acknowledge or Clear . For further information, refer to

either “ Acknowledging an Alarm

” on page 63 or “ Clearing an Alarm ” on page 65.

The Alarm list view allows you to choose from four different perspectives on alarms:

Current Alarm(s)

Error Instance(s)

Related Host(s)

Related Agent(s)

Current Alarm(s)

By default, you see the list of alarms with the ability to sort the alarms by different elements (Severity, Time, Ack’ed, Cleared, Host, Instance, Message, Origin, Agent,

Agent Type).

Error Instance(s)

The Error Instances option lists the agents containing data that triggered an alarm in the

Outstanding Alarms table. For each error instance triggered, it indicates its state of health, number of each type of alarm, and its health history.

In the example shown below, the alarms are grouped according to their source (Long

Name).

Related Agent(s)

A useful way to understand which agent is causing an alarm to fire is to show alarms organized by the agent that collected the data. You can expand each agent node to see where the agent is gathering data.

The example below shows that the Application Monitor agent is firing fatal alarms and critical alarms are coming from the Windows System agent.

“ Filtering the Alarms View ” on page 62.

As a visual cue, cleared alarms appear dimmed out. This applies to all alarms that are

cleared regardless of the time range. You can add a new note (see “ Alarm Notes ” on

page 70) or acknowledge an alarm (see “ Acknowledging an Alarm ” on page 63), even

though it is cleared. The Cleared column in the Outstanding Alarms view indicates the status on whether a cleared alarm was not acknowledged (N) or the cleared alarm has been acknowledged (Y).

If the same condition that caused the alarm to fire occurs again in the next sampling interval, the alarm will reappear in this table.

To clear an alarm:

Instance

When you select the instance of the alarm (e.g. in the Alarm list when looking at a list of

Outstanding alarms, or when looking at alarms grouped by Alarm source), a common health summary for the data that triggered the alarm appears:

Working with Dashboards

Common Views

67

Figure 11

The health summary:

• shows the number of alarms by severity and the overall health of the selected alarm source.

• provides links to the agents and host for the alarm source.

• provides a list of related views that show quick drilldowns to help identify the root cause. This list is based on the views that match the type of the alarm source.

The related views are often provided by cartridges. If no related views are available, then the default views (e.g. Data Browser, Summary) are provided.

Alarm Details

The Alarm Details summary is shown when an alarm message, severity icon, alarm time, or agent type is selected.

You can check alarm details to view more information about an alarm in the alarms table. For example, if you are concerned about a particular alarm, click the alarm severity in the alarms table to view the alarm details. On the alarm details dialog box you can view the table that illustrates how the alarm has changed state in the current time range.

The Alarm Details dialog box shows alarms related to the current alarm in the given time range, acknowledgement information of these alarms (such as whether an alarm has been acknowledged or is not acknowledged), clearing information of these alarms, and any alarm notes added to these alarms.

The alarm details view also shows the full alarm history. This includes all consecutive alarms fired by the same rule on the same instance regardless of the time range. The default for 'consecutive' is 5 seconds.

For example, after acknowledging an alarm you can include a note and details as to the alarm. All users can view and create a note but only the author of the note can edit or delete an existing note. Notes can be added to any alarm at any time even after the alarm has cleared. Alarm notes display:

• Created Time (time when the note was created)

• Description of the note

• User who created the note

• An Edit icon to enable the creator of the note to change the note description.

For more information, see “ Alarm Notes ” on page 70.

Alarm Notes

Alarm notes provide you with a handy way to record information about an alarm for all other users to view. For example, if you are managing alarms during an installation of vFoglight and if an urgent alarm comes up, you can add a note to the alarm that you are checking if the back-up process may be causing the problem. The note, along with a username stamp and a timestamp, are attached to the alarm.

There are two ways you can add notes from the Alarm Details dialog box by using either the:

• History tab. The Notes icon in the Alarm History table is for maintaining notes attached to a particular alarm in the history table. Clicking the Notes icon, takes you to the Alarm Notes dialog box.
