Global Application Delivery dashlet

The Global Application Delivery dashlet enables you to compare the performance and end-user experience of your web application by geographic location.

Global Application Delivery dashlet

Using the Global Application Delivery dashlet, you can identify where end users are frustrated, based on your configured geographic performance-compliance levels (Geo PCLs) for a global view of how your web application is performing.

• Geographic Performance Compliance Levels (Geo PCLs) — Configurable criteria
  Unknown macro: {multi-excerpt-include}
  uses to characterize the end-user experience of server or application performance in a given region. Using Geo PCLs, the system characterizes end-user experience in a given area as Satisfied, Tolerating, or Frustrated.
• Performance — The measure of how well a server or application instance is functioning, as measured using the End-to-end time or Page-render time metric

Monitoring options

You can view information in different ways on the Global Application Delivery dashlet.

Getting detailed information on the dashlet

By default, the dashlet represents data on a map. For more detailed information, you can view the same data in the Grid View, where you can sort data by performance compliance, zone, traffic volume, and latency values.

Changing the data display on the dashlet

You can filter out data that you do not want to see on the dashlet using the Display options panel, shown in the following figure and which you can access using the button on the right of the dashlet.

Display Options Panel

For example, in Map View you can use controls on the Display options panel to show only areas where end users are characterized as Frustrated, or only areas reporting high traffic volume.

View live or historical data

You can see live data on the dashlet as the system collects it, or you can browse historical data for the last 72 hours or the last 30 days. You can also use the timeline selector to view data for a specific time.

The system aggregates data for each time period option as follows:

• Every five minutes for Live data
• Every five minutes for the Last 72 hours
• Every hour for the Last 30 days

Replay historical data on the map

You can play back changes in traffic and Geo PCL data on the map for the last 72 hours or the last 30 days by dragging the timeline selector to the date from which you want to replay data and clicking the Play button.

Configuring the dashlet

When configuring the Global Application Delivery dashlet (on both

• Which Geo PCL definition that you want to display on the dashlet
• How you want the system to display data on the map
• Which optional features that you want the dashlet to display

Selecting a Geo PCL definition

A Geo PCL definition is a distinct entity that you configure to monitor end-user experience of your web application for a specific Watchpoint in the geographic zones that interest you. You can configure a Geo PCL definition for each web application that you want to monitor. The Geo PCL definition determines which areas are represented by circles on the map.

Displaying data on the map

In the Data display section, you determine how you want

• Selecting which data to display — By default, the system shows both Geo PCL and traffic data on the dashlet. You can change the dashlet settings to display only traffic data or only Geo PCL data. You can select from the following options:
  • Geo PCL and traffic volume data — Each area is represented by green, yellow, or red circle to indicate whether end users are Satisfied, Tolerating, or Frustrated. Large circles indicate high traffic volume, and small circles indicate low traffic volume.
  • Geo PCL data only — Each area is represented by green, yellow, or red circle to indicate whether end users are Satisfied, Tolerating, or Frustrated. All circles are the same size.
  • Traffic volume data only — Areas are represented by circles of the same color (you can specify the color). Large circles indicate high traffic volume, while small circles indicate low traffic volume.
• Aggregating data for areas on the dashlet — To eliminate atypically high latency values or display all calculated values on the map as an average or maximum, you can select the calculation that the system uses to show data on the dashlet. By default, the dashlet aggregates data by calculating the 85th percentile of all latency values for each time period in a given area. (This means that for 85% of users in a particular area, latency is equal to or below the value displayed on the dashlet, representing typical experience of your web application.) You can use other percentiles to aggregate data on the dashlet, or configure the dashlet to calculate the average or maximum value for the latency values for each time period in a specificarea.

To configure the dashlet on the Analyzer component

1. On the dashlet shortcut menu, click Edit settings.
2. Configure basic settings for the dashlet, as follows:
   • In the Geo PCL definition list, click the Geo PCL definition that you want to display data for.
   • In the Data display section:
     • Select the data that you want the map to show. You can display Geo PCL and traffic data, only traffic data, or only Geo PCL data.
     • Select the calculation that you want to use.
     • Specify how large you want the circles representing traffic volume to be (in pixels).
3. Configure advanced settings for the dashlet, as follows:
   • (Optional) To display timelines that show performance compliance by area over time, select the Geo PCL timelines check box.
     Geo PCL timelines are only displayed in the views for Last 72 hours and Last 30 days.
   • (Optional) To display the live status ticker, select the Ticker check box and specify the following options:
     • Enter the maximum number of areas that you want the ticker to display.
     • In the Sort areas by list, specify how you want to sort areas in the ticker:
       • To sort the areas on the ticker by the amount of traffic coming from each area, click Traffic volume.
       • To sort the areas according to traffic volume change in a specific area, click Requests (absolute number) or Percent (relative value).
       • To sort areas alphabetically by name, click Name.
     • If you want the ticker to report only areas where the traffic has changed by a certain percent since the last timeframe, enter a value in the Only report traffic volume changes greater than or equal to text box.
     • (Optional) To display the origin location marker, click the Show origin location marker check box and type the public IP address of your web server.
4. Click Save.

To configure the dashlet on the Console component

1. On the dashlet shortcut menu, click Edit settings.
2. Specify the Watchpoint to show traffic for.
3. In the Metric field, select either End-To-End or Page-Render Time.
4. In the Aggregate By field, select the type of data aggregation.
5. In the Data display field, select the kind of data to display:
   • Geo PCL and Traffic volume data
   • Geo PCL data only
   • Traffic volume data only
6. In the Smallest Traffic and Largest Traffic fields, provide the size of the smallest and the largest bubbles on the dashlet.
7. Click Save.

Getting details about data on the dashlet

To display the value that a point on a graph represents, move the pointer over a bar in a bar graph or anywhere in the region overview.
A tooltip shows the details.

To highlight recent changes on the dashlet or trends over time, you can configure the dashlet to display Geo PCL timelines or a live status ticker.

• Geo PCL timelines — Available only for Last 72 hours and Last 30 days intervals.
  Geo PCL timelines are graphs that display performance compliance data for each area over the past 72 hours or 30 days.
• Live status ticker — Available only in Live mode. The live status ticker displays traffic volume and performance compliance changes that occurred since the last five-minute timeframe was displayed.

You can configure the ticker to display only a certain number of areas and sort by traffic volume or name.

To inspect regions data on the session level:

1. Click the bubble that represents the region that you are interested in.
2. In the tooltip that appears, click Drill down (for the Analyzer component) or Analyze (for the Console component).
   This action drills down to Session Browser, where you can inspect all sessions from the selected region in greater detail.
