Use the Global Application Delivery dashlet to identify problems in traffic volume and performance that end users are experiencing in various locations. For example where the highest traffic comes from or which area has the biggest performance issues. The following topics describe how to configure and use this 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, Map View
A Global Application Delivery dashlet is based geographic performance-compliance levels (Geo PCLs) that you configure and enable. Geo PCLs characterize the end-user experience of server or application performance in a given region as Satisfied, Tolerating, or Frustrated. Performance measures how well a server or an application instance is functioning, by using the E2E Latency or the Page-Render Time metrics. For definitions of these metrics, see End-user experience metrics.
Notes
The way that you work with a dashlet on mobile devices differs from the way that you work with it on a computer:
On the Global Application Delivery dashlet, you can monitor and view information in the following ways:
By default, the dashlet represents data on a map. It highlights areas on the map where users experienced issues with traffic volume and performance.
To inspect regions data on the session level:
Note
The drill-down feature shows results only for data where the IP address corresponds with a defined region or city. The geolocation database in the system does not automatically associate all IP addresses with a region or city.
After you analyze data on the map, you can view more detailed information in the Grid View, where you can sort data by zone and latency values.
Global Application Delivery dashlet, Map View
You can filter data on the dashlet by using the display options panels for Map View and Grid View, shown in the following figure. You access either of these panels by using the arrow button on the right of the dashlet.
Display options panels
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.
Notes
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. Starting with the version 2.6.00 of the BMC Real End User Experience Monitoring, the Global Application Delivery dashlet shows data in the time zone configured on the BMC Application Management Console. For more information, see 2.7.00 enhancements.
Using the time selector in the Grid View
The system aggregates data for each time period option as follows:
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 ( ).
The dashlet is available in both the Real User Analyzer and the BMC Application Management Console; however, you configure it differently on each component. When configuring the Global Application Delivery dashlet, you must specify the following items for both components:
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.
The Data display section determines how you display data on the map. By default, the system shows both Geo PCL and traffic volume data on the dashlet. You can change the dashlet settings to display only traffic volume data or only Geo PCL data. You can select from the following options:
To select data display method on the map:
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. 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 specific area.
(Optional) Configure advanced settings for the dashlet, as follows:
To display the value that a point on a graph represents, click the bubble on the graph.
Getting details in Map View
To get the information that a cell in the Grid View represents, move the pointer over the needed area. A tooltip shows the details.
Getting details in Grid View
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.
