Global Performance Tracker dashlet (Real User Analyzer)
The Global Performance Tracker dashlet enables you to graph the performance and end-user experience of your web application, broken down by geographic zone. You can identify geographic areas where end users are frustrated due to performance issues, based on geographic performance-compliance levels (Geo PCLs) that you have configured. You can also use this dashlet to compare the performance in each geographic zone before and after a specified date.
Global Performance Tracker Dashlet
Geographic Performance Compliance Levels (Geo PCLs) are configurable criteria that the system uses to characterize the end-user experience of server or application performance in a specific region. Using Geo PCLs, the system characterizes end users in a given area as Satisfied, Tolerating, or Frustrated.
Monitoring performance compliance
This dashlet offers several ways to help you monitor performance compliance:
- By geographical zone — The dashlet shows a performance graph for each geographic zone defined in the Geo PCL definition being used by the dashlet. Using this graph, you can see geographic areas where end users are receiving frustrating performance, as well as compare the relative performance experienced by end users from each area.
The system is preconfigured with a Geo PCL definition that defines geographic zones for Africa, the Asia-Pacific region, Australia, Central America/Mexico/the Caribbean, China, Eastern Europe, Western Europe, India, the Middle East, North America (East, West, and Central), and South America. You can create custom Geo PCL definitions to change the geographic zones.
- Around a specific date — The dashlet shows graphs centered on a particular date, which is denoted by a white line in the middle of the graph. The end-user performance metric is graphed for the time period before and after this date. You can compare the performance of your web application before and after a particular date, such as a date when a major change was implemented in your web application.
Each performance graph has the following features:
- The name of the geographic zone being graphed
- Violation count: The number of times when performance exceeded the Frustrated threshold, before and after the pivotal date
- Tolerating threshold indicator: A yellow horizontal line on the graph showing the Tolerating threshold
Frustrated threshold indicator: A red horizontal line on the graph shows the Frustrated threshold.
You can configure the Tolerating and Frustrated thresholds in the Geo PCL definition on the Geographic Performance Compliance Levels (Geo PCLs) Administration page.
- Graph line: The graph is colored green, yellow, or red, depending on whether the performance metric was normal, tolerating, or frustrated. This information lets you see whether the performance was acceptable, as well as how often the performance exceeded these thresholds.
Hovering the pointer over the graph line shows a tooltip with details about the specific performance metric value at that moment.
Configuring the dashlet
Set up the dashlet to monitor the performance data from a Geo PCL definition on a series of graphs, broken down by geographic zone.
Configuring the Global Performance Tracker dashlet includes:
- Selecting a Geo PCL definition for the dashlet to display
- Selecting a pivotal date and duration for the dashlet to display
The Geo PCL for which you want the dashlet to show data must be configured and turned on.
To configure the dashlet
- On the dashlet shortcut menu, click Edit settings.
To configure the Geo PCL definition that the dashlet will use, in the Geo PCL definition list, select the Geo PCL definition that you want to use.
You can configure Geo PCL definitions for each web application that you want to monitor on the Geographic Performance Compliance Levels (Geo PCLs) page.
- To configure the pivotal date and time range that the dashlet will display:
- In the Pivotal Date box, enter the pivotal date that you want to use in the MM/DD/YYYY format, or use the calendar to select the date.
- In the Duration list, select the interval to show on the dashlet (7 days before and after the pivotal date, 14 days before and after the pivotal date, or 30 days before and after the pivotal date).
The Before Period and After Period dates change as you update the Pivotal Date and Duration settings. This information gives a preview of the exact time ranges that will be shown on the dashlet.
- Click Save.
