Monitoring an Application

You use the Application Details dashboard to monitor the details of a single application.

It shows the structure of the application (tiers and flows), as well as the alarms for the application and its service impact.

Figure 1

The following views appear on the Application Details dashboard:

• Tier Overview view contains an icon for each tier. Clicking an icon opens a view with details of that tier and links to related views.

• Application Contents view lists the components of the selected application. For each component it indicates the state of health, number of each type of alarm, and health history.

• Outstanding Alarms view lists alarm information for the selected application.

For a description of this view, see “ Alarm List ” on page 58.

• Service Impact view lists services that may be affected by a problem with the selected application.

Building an Application

An application is a set of tiers in which each tier contains a set of monitored elements, such as hosts and servers. A tier has a defined flow that represents the data moving from the user to the back-end systems.

The Application Builder dashboard is where you create a new application from scratch.

It contains all the functions needed to build an application model in three views — one for each step in the process.

• In the Step One view, you add tiers to an application or edit the tiers in an existing application.

• In the Step Two view, you create tiers and define the flows and components for tiers.

• In the Step Three view, you inspect the application.

Note A new service is automatically created for a new application.

Step 1: Adding Tiers to an Application

Adding an application involves creating a set of application tiers that make up the different logical layers of the application. After the tiers are identified and created, they can be linked to show a logical flow of information. This makes it easier to understand the dependency between tiers. When you add vFoglight objects to the tiers, states begins to flow up to the tiers. The result is a model that shows which logical part of an application is causing a problem.


You can also add an application using the Service Builder Dashboard. See “ Creating a New

Application ” on page 109.

To add tiers to an application:

1 In the navigation panel, expand the Applications node and select Application

Builder .

The Application Builder is displayed.

2 In the Step One view, click Add drop-down list.

The Application Creator dialog box appears.

3 Type a name that is unique to vFoglight for the application and click Create .

The name of the new application is added to the drop-down list in the Step One view.

4 Choose the new application you just created from the drop-down list.

Step 2: Creating Tiers, Defining Tier Flows and Tier Components

Creating Tiers

The following steps describe the procedure to create new tiers. If the tier already exists,

you can add the tier to the application. See “ Step 3: Adding Tiers to Preview the New

Application and Tier Flows ” on page 159.

To create a tier flow:

1 To create a new tier for the application, in the Step Two view click the Add icon


The Tier Creator dialog box appears.

1 Select the Tier Type (e.g WebTier, DatabaseTier, etc. ) from the drop-down list.

2 Type a name for the tier and click Create .


The name of the new tier is added to the drop-down list and appears under Add a


Continue to add new tiers to the application if required.

Defining Tier Flows

When you define tier flows you are specifying the workflow sequence from one tier to another.

To define a tier flow:

1 In the Step 2 view, choose the tier from the drop-down list in which the flow originates.

Step 3: Adding Tiers to Preview the New Application and Tier


When you have finished adding tiers to the application, you can preview the new application in the Stepand tier flows in the Step 3 view.

To add Tiers to the Application:

1 Under Add a Tier, click Add for each tier(s) you want to add to the new application.

2 The tiers you added moves to the list under Current Tiers and you can preview the application tiers and flows in the step 3 view.
