Application overview dashboard

The application dashboard displays the discrete applications under Others and the custom applications that are grouped under their respective categories. You can either select Treemap view or Tiles view to view the applications. The applications are displayed in the Application Overview dashboard, representing with variations of colors (red, blue, and grey).

Navigate to Application > Dashboard to view the app dashboard.

Application-dashboard

The following table provides you the information about the various options available in Application Overview dashboard.

app-health Denotes the color legend of the App Score, where:
  - 0, 20, 30 – Low score
  - 40, 50, 60 – Medium score
  - 80 and 100 – High score

refresh Enables you to refresh and get the details immediately
export Enables you to export the current data to a PDF or PNG format
expand Expands all sections of summary/App Info panel
collapse Collapses all sections of summary/App Info Panel
change-page Enables you to select the previous page and next page

By default, 250 applications are displayed on the application dashboard. To view more applications, click next-page

App Summary Panel

The App Summary Panel is displayed on the right-side of the Application Overview dashboard page, with the following metrics for all the applications:

Note

When you hover-over the cursor on the histogram, it displays the total number of applications associated based on the metrics. When you click on the histogram, the relevant applications are displayed in the Application Overview dashboard. You can click clear to clear the filter.

Metrics Description Example
App Score A histogram representation to show the categorization of App score for the applications app-score
App Category A histogram representation that displays all categories defined in Citrix ADM. All discrete applications appear under,” Others” category, and custom applications appear under their respective category names app-category
Virtual Server Health A histogram representation that displays the number of applications between the score range 0% to 100%. The N/A is for the other applications except load balancing and content switching virtual-server-health
Data Volume A histogram representation that groups the number of applications depending on the data volume of the application. Data volume is calculated by the total number of bytes requested by the applications and the number of bytes received as responses from the applications datavolume
Transactions A histogram representation that displays the range of transactions performed by the applications transaction
Client Connections A histogram representation that displays the number of client connections established by the applications client-connection
Server Connections A histogram representation that indicates the number of server connections established by the applications server-connection
Packets Sent A histogram representation that indicates the number of packets sent by the applications packet-sent
Packets Received A histogram representation that indicates the number of packets that are received by the applications packet-recevied
Application Class A histogram representation that groups the number of applications depending on whether they are discrete or custom applications application-class

App Info Panel

The App Info Panel is the first-level option to drill-down an application information. When you click on any application from the Application Overview dashboard, the App Summary Panel is replaced and displayed with App Info Panel.

The App Info Panel shows the total number of virtual servers, total number of services, overall app score, packets sent, packets received, transaction details, and so on.

App usage analysis

This is the second-level option to further drill-down the application performance. For example, let us consider you have a group of applications under datacenter 2 category and the load balancing application shows as low performance. You can check the Peak Usage trend to analyze the performance of the application and take decisions to improve the application performance.

app-usage

You can further click details-icon in Peak Usage section to view the App Score and the application usage. Using this information, you can identify the peak usage of the application and associate it with the corresponding App Score to assess the performance impact on the application during the peak usage duration.

App Activity investigator

App activity investigator is one of the second-level options to drill-down the application performance. When you double-click on any application, the detailed view of the application is displayed.

App Score defines how well an application is performing and shows whether the application is performing well in terms of responsiveness. App Score is displayed at the application level. Calculation of the score is based on the following three key components:

  • App Performance Score. Derived from the server response time variation of the application.

  • Citrix ADC System Resource. Derived based on three more components:

    • CPU Usage

    • Memory Usage

    • NIC Card Saturation

  • App Server Resource. Derived from two more components:

    • Percentage of Active Services

    • Surge Queue Requests

App Score is calculated from these scores where Citrix ADC System Resource Score and App Server Resource Score is subtracted from App Performance score. App Score is available for all the applications defined with load balancing and content switching virtual servers that are discovered and the custom applications defined on the application dashboard.

To configure App Score:

  1. Navigate to Analytics > Settings.

  2. On the Settings page, click Configure App Score.

  3. On the Configure App Score page, enter the values for the following parameters:

    1. Lower Surge Queue Threshold. The lower threshold value of the ratio of the total number of connections that are pending submission for the virtual server and the established connections.

    2. Higher Surge Queue Threshold. The higher threshold value of the ratio of the total number of connections that are pending submission for the virtual server and the established connections.

    3. Low CPU Threshold (%). The lower threshold value of the total CPU usage in the Citrix ADC instance.

    4. High CPU Threshold (%). The higher threshold value of the total CPU usage in the Citrix ADC instance.

    5. Low Memory Threshold (%). The lower threshold value of the total memory usage in the Citrix ADC instance.

    6. High Memory Threshold (%). The higher threshold value of the total memory usage in the Citrix ADC instance.

    7. Low NIC Discards. The lower threshold value of packets discarded by the interfaces.

    8. High NIC Discards. The higher threshold value of packets discarded by the interfaces.

    9. Server Response Time (ms). The time interval between sending a request packet and receiving the first response packet from the service configured on the virtual server. Default value configured in Citrix ADM is 500 ms.

    10. Active Services Threshold (%). The threshold value of the percentage of services that must be active which are bound to the virtual server.

  4. Click OK.

After you configure thresholds, any deviations occurred greater than the configured scores are displayed as color-coded graphs. When you double-click on the application, the App Activity Investigator is displayed with the components such as Response Time, Average CPU Usage, Memory Usage, and so on.
