Managing application components

The Application Components category provides metrics from the perspective of a web-based application or subset of an application. On the Application Components page, accessed by navigating to Configure > Applications > Application Components, you can define application components and instrumented application components that your system should monitor.

Figure 75. Application Components page

The metrics of an application component represent an aggregation of the metrics for all of the URLs that match the regular expressions that are defined in the application component. By defining application components, you can monitor web-based applications as a single entity, so that performance metrics and SLA compliance can be evaluated from the perspective of the application as a whole.

The metrics of an instrumented application component represent an aggregation of the metrics that are tracked by FxM using the browser-based instrumentation. An instrumented application component is defined as a subset of pages that have URLs matching one or more regular expression patterns. These pages have been instrumented to return metrics to the originating web site from the user’s browser (for details, see “Configuring browser-based instrumentation” in the Foglight Experience Monitor Installation and Administration Guide).

Defining an application component

Configuring an application component involves defining a set of regular expressions, assigning service level thresholds, and selecting appropriate distribution configurations.

To define an application component:
1
Click Add a new Application Component, located at the bottom of the Application Components section.
This displays the Application Components > Edit page.
2
Name the Application Component Definition
In the Name box, type the symbolic name you want to associate with this application component.
Each application component must have a unique name. Use this name to locate the metrics recorded for it in the web console.
3
Set the Application-Related Service Levels
a
In the End-to-End Time Service Level Threshold box, type the desired service level for the end-to-end time associated with this application component.
For example, if you decide that most of the page downloads for this application component should be serviced within five seconds, enter 5000 (units are in milliseconds).
The End-to-End Time Service Level metric shows you the percentage of page downloads that satisfy this service level. For information on how this metric is calculated, see Page End-to-End Time in the Foglight Experience Monitor Metric Reference Guide.
b
In the Processing Time Service Level Threshold box, type the desired service level for page processing times associated with this application component.
For example, if you decide that the time to process the pages of this application component should generally not exceed two seconds, enter 2000 (units are in milliseconds).
The Page Processing Time Service Level metric shows you the percentage of pages whose processing time satisfies this service level. For information on how this metric is calculated, see Page Processing Time in the Foglight Experience Monitor Metric Reference Guide.
4
Set the Application-Related Distributions Configurations
a
In the End-to-End Time Distribution Configuration box, select the desired distribution configuration for the end-to-end time associated with this application component.
This option allows you to specify the buckets and ranges of the distributions.
b
In the Processing Time Distribution Configuration box, select the desired distribution configuration for page processing times associated with this application component.
5
Add Regular Expressions
For existing application components, the Regular Expressions section lists all the regular expressions that have been defined. Since you are defining a new application component, this section is empty.
a
Type a regular expression in the box. For example, if you know where the application components are located (all components are found under quest.com/support/), enter the expression (in this case, quest.com/support/.*).
Multiple regular expressions can be added.
b
Click Add and proceed to Step f.
c
Alternatively, if you don’t know where application components are located, click the Pick a Directory link to display a window that lists the directories in use on your site. This window allows you to easily select an existing directory to serve as the basis for a regular expression. By selecting an item in this window, the box is initialized with a regular expression that matches the directory you chose. This list is not obtained by an active search of your web site but rather from the list of URLs that have been monitored and recorded by the appliance in the past.
d
From the Directory List, navigate to and select a directory.
This directory is added to the Selected Directory section. Some directories contain subdirectories (directories that are nested beneath the top-level directory. For example, siebel.prod.quest.corp is a subdirectory of siebel.
e
Click OK.
f
To display a list of URLs that match the regular expression and application component definition, click Test.
 
* 
NOTE: This test is performed against the list of URLs that have been monitored and recorded by the appliance in the past.
g
Close the Application Test window when you are finished reviewing the resource list.

Editing an application component

You can modify an application component definition by clicking its corresponding Edit link, which takes you to the Application Components > Edit page. In the Application Component Definition section, you can edit the application component name, set service level thresholds and select distribution configurations.

 
* 
NOTE: If you modify an existing application component definition name, this change takes up to 30 minutes to propagate throughout the metrics that are displayed in the web console.

You can also modify the regular expressions that identify the application component. Select the check box that corresponds to an expression, and then click Delete to remove it. You can then replace it by adding regular expressions in the manner outlined in the previous section.

In the End-to-End Time Distribution Configuration and Processing Time Distribution Configuration lists, choose the appropriate distribution configuration for each of these metrics. See Distribution metrics.

Deleting an Application Component

To delete an application component from the list displayed in the Application Components page, select its corresponding check box and click Delete.
