The Application View enables you to monitor the performance of an application over time. The view helps you pinpoint issues in the application and locate servers where you can begin investigating problems. You can examine and trend server metrics and correlate server issues with application transaction issues.

The Application View shows color-coded application tiers that represent the status of problems in a transaction, on a server, or on a page. Problems are generated by the system under the following conditions:

  • Performance (latency) violations on a transaction or page
  • Availability errors on a transaction

Two types of threshold violations are represented:

  • Warning thresholds (orange tiers, members, or pages) are lower values that indicate attention might be required
  • Critical thresholds (red tiers, members, or pages) are higher values that indicate a more severe situation.

For information about the default event thresholds, see Application server events.

Application View elements

With the Application View, you can pinpoint the application, date, time, and problem that you want to investigate. The following image is an example of the navigation elements in the Application View.

The numbers in the following list correspond to the numbers in the Application View example image:

  1. Application list—Select an application from the list of monitored applications.
  2. Date picker—Date of monitored data that is currently displayed. Click the date to select a specific date, or click an arrow to go to the next or previous date.
  3. Time picker—Click an arrow to go to the next or previous five minute block on the time slider.
  4. Problem picker—Click an arrow to go to the next or previous problem. The color of the arrow indicates the severity of the next or previous problem.
  5. Live Traffic button—Click Live Traffic to display the most recent status recorded from the application. Click the button again, or move the time slider, to stop the constant updates.
  6. Time slider—Selects specific five-minute intervals from the active 24-hour time period

The Application View includes the following tiers that represent different the functions and functionality of your application:

  1. User tier—Color-coded box that reflects the status of the user experience based on how well page performance compares to the page end-to-end time thresholds set for the application.
  2. Application server tiers—Color-coded boxes reflecting the status of service level agreement (SLA) thresholds for transactions (latency violations and errors) and application servermetrics. Each Diagnostics Agent is associated with one of the following application server tiers:
    • Web tier
    • App tier
    • Business tier
  3. Database tier—Color-coded box reflecting threshold breaches or errors. Details are based on exit point data.

After you select a tier, you can scroll down and examine more details in the Problems and Metrics views. 

Before you begin

To monitor application health and performance with the Application View

  1. Log in to the Application Management Console.
  2. On the Application Monitoring tab, click the Application View menu.
    The following elements are displayed for a selected application:
    • Tiers for the selected application that are color coded according to status. 
      • Blue—no data
      • Green—no problems
      • Orange—warning
      • Red—critical
    • Results from the last 24 hours
    • The Live Traffic button is selected so that updated results are continually displayed every five minutes
  3. From the Application list, select the application for which you want to see data.
  4. To view data from a specific date or at a specific time or date, click the date picker and then move the slider to a specific time segment of the selected day, or click the Problem picker.
    Click Live Traffic to return to current updates. 
  5. To view data about a specific tier, select the tier. 
    Associated members (application servers, databases, or pages) are displayed in the Tier Members section of the Application View.
  6. Select one or more a tier members to see a more detailed analysis:
