Monitor a Web Application (Monitor Application)

The Monitor Application dashboard gives Application Owners a quick view on any application (desktop, mobile or web), including its performance, health, and the extent of its usage in your organization, to proactively check if any issues arise, or if any reported issues might be due to that application's deployment.

Application Owners can use this dashboard as their launchpad for an overall summary of the status of their application, and to quickly jump to the main use cases of this application using the quick jump menu.

For example, if your web application is suffering poor performance, you can easily see the impact from the usage time and number of users, to see how widespread the problem is, and you can see the locations of poor performance, and determine the trend to see if the situation is worse or better than before.

This dashboard uses the UXI as a key indicator of performance. The User Experience Index (UXI) is a value (0-5) which measures the overall performance and health of an application, based on several inputs: the number of crashes per hour of out the total usage time, the percentage of hang time of out the total usage time, the percentage wait time of out the total usage time. For web applications, it also uses the percentage of web page errors out of all page loads, and the average page load time. These ingredients come together to represent the overall experience of a user.

For each element of the UXI, we determine a narrow range of meaningful results, beyond which it is flattened to either zero or the maximum. For example, a regular application should have 0% hang time, so anything above 5% would be unacceptable, therefore the hang time index would be zero, which drastically lowers the overall UXI score for that application.

Definition of user experience index (UXI)

This index is an absolute (not relative) measurement, since it does not depend on baselines which may vary between applications or locations, equivalent to the global energy star ratings used for appliances. Therefore the system can accurately display a single objective measurement across several attributes. For example, it can display this index for a single user on a single application, or many users on a single application, or many users on many applications.

Field Description
Summary bar

View a summary of the health of the application at a glance, and whether it has improved or worsened (see below).

Departments / Business Locations / Regions / Operating Systems / Device Types

Assess the business impact of poor performance by viewing the parts of your organization which are worst hit. Quickly view those with the lowest performance, poorest activity scores, or the heaviest users of applications.

Select a category from the drop-down menu: departments, business locations, regions, device types or operating systems.

For more information, see the step below.

Usage

At a glance, you can view a map of how and where an application is used. Choose from the drop-down to see the departments which use this application, the business locations where it is run, the device types (if it is run on desktops, laptops, mobile devices), browser versions, and the range of operating systems.

Geographies

Check if a poor performance is confined to a specific location, by viewing data by locations displayed on a geographical map.

Usage Trend

See the recent trend in efficiency for this application, by viewing the recent changes in usage times and wait times during the dashboard's timeframe.

For more information, see below.

Activity Performance

(Managed applications only) With a quick glance, you can view a graph of the activities which are performing well or poorly, and how widely they are used. For more information, see below.

Activity Score

(Managed applications only) At a glance, see the trend of the application's performance during the dashboard's timeframe, by viewing the changes in the score (and status) of activities for this application.

Activity Response

(Managed applications only) View the trend of the application's performance during the same timeframe, by viewing changes in the average activity response time (in seconds).

The response times of activities are split into client time ( dark blue), and the combination or union of the server time ( light blue) and the network time ( blue).

Use the actual response times (not scores) to check the performance of chronic (long term) problems. You cannot rely on measurements based on the recent baselines, as those responses would be chronically slow for some time, thereby skewing baselines to make those times look normal.

Page Performance

Displays the recent average web page load time for all pages of this application. The response times of activities are split into client time ( dark blue), and the combination or union of the server time ( light blue) and the network time ( blue).

The web page load time is defined as the time required for a web page to load and finish rendering in a browser, from sending a URL request to when the page's events finish loading and it has a status of Completed. This measurement does NOT include the time to load additional page elements which occur after the main page has loaded (like Ajax calls which are measured separately, or iframes which are embedded separate web pages, or bookmarks with # in the URL).

The infra time for a web application (which is the network and server time) starts when you request the URL, and ends when the browser receives its last response from the server. The remainder, like processing and rendering of the objects, is the client time.

Throughput

View the recent usage of this web application, displayed as the average number of times when a new web page was requested per minute.

For example, if a user enters a URL and loads a web page, it counts as a single page request. If a user refreshes the same web page, it counts as an another page request. This measurement does NOT relate to the mini HTTP requests within a single web page.

Error Rate

(Web applications only) The web page error rate is the percentage of web page errors (HTTP error 40x or 50x) out of all page loads in web applications. This is one of the elements used when calculating the UXI. For example, if the requested page cannot be found, it issues HTTP error 404. If you are not authorized to view a web page, it returns HTTP error 50x, and so on.

Users

You can assess the impact of any performance issues, by viewing the recent changes in the number of unique users who actively used an application (in the foreground) during that time.

Data Center Locations

(Virtual deployments only) Monitor the application's performance by:

  • Data Center Locations in Aternity lists the locations of any virtual application servers (like Citrix XenApp) and VDI hypervisors (like in VMWare vSphere) which run the application. If the application is deployed both locally and virtually, one of the locations displays as Local.

  • Virtual App Servers displays the name of each virtual application server (like Citrix XenApp) running this application.

For each item, it also displays the number of users, the usage time and wait time, the UXI, and (for managed applications only) the activity score.

Remote Display Latency

Displays the overall latency for virtual sessions (or lag) in seconds for each type of virtualized environment (virtual desktops and virtual applications), gathered from latency measurements taken every minute. It lists the following protocols (if present in your organization):

  • ICA is the protocol used by Citrix XenApp.

  • RDP is the protocol used by Microsoft products like Remote Desktop Connection. It is also increasingly being adopted by newer versions of Citrix XenApp.

  • PCoIP is the protocol used by VMWare's VDI systems.

    Usage Time

    The usage time of an application is the total time it is running, in the foreground, and being used. This includes the wait time, the time a user spends waiting for the application to respond. For web applications, the usage time is when both the browser window and the application's tab are in the foreground.

    User Experience Index

    The User Experience Index (UXI) is a value (0-5) which measures the overall performance and health of an application, based on several inputs: the number of crashes per hour of out the total usage time, the percentage of hang time of out the total usage time, the percentage wait time of out the total usage time. For web applications, it also uses the percentage of web page errors out of all page loads, and the average page load time.
