Web Insight

Web Insight enables visibility into enterprise web applications and allows IT administrators to monitor all web applications being served by the Citrix ADC by providing integrated and real-time monitoring of applications. Web Insight provides critical information such as user and server response time, enabling IT organizations to monitor and improve application performance.

Latency in applications

As an administrator, you can now identify the source of latency issues faced by users while accessing web applications. You can determine whether the issue is occurring on the server side of the network, the client side of the network, or on the application server itself.

Using Citrix Application Delivery Management (ADM), you can locate the issue by navigating to Analytics > Web Insight > Applications and selecting an application. The response time for an application is typically broken down into 3 sub-parts to show whether the problem is a client network latency issue, server network latency issue, or an overloaded or malfunctioning server.

You can also see which specific server has highest server processing time for that application.

Inaccessibility issues

As an administrator, you can now see which application servers are currently generating erroneous response codes, such as unauthorized, bad request, or page not found, so that you can take appropriate corrective measures.

Navigate to Analytics > Web Insight > Response Status, and click on a specific error code (such as Unauthorized) to identify which application servers sent that response code.

Thresholds

Administrators can use Web Insight to configure thresholds and notify users about threshold breaches.  In a typical deployment, you can automate the process of tracking various application metrics, to facilitate planning and be notified whenever the applications metric value exceeds the set threshold. You can set thresholds for any metric, such as hits, bandwidth, or response time.

For example, you can configure a threshold for response time. When the response time of a particular application exceeds the threshold value, you will receive a notification on your dashboard. Also, under Threshold Breaches, your dashboard displays a list of threshold breaches that have occurred for a specific duration (such as Today).

To configure a new threshold, navigate to Analytics > Settings > Thresholds, and click Add.

Browsers and operating systems

You can use Web Insight to help you segregate L7 latency issues and understand mobile device usage uptake. This can help you, as an administrator, to understand different operating system uptakes across your user base.

You can go to the Browser pane to see why there is slowness in user access and if it is due to incompatibility across certain browsers. You can also see which operating systems are being used across certain clients, and the browsers being accessed. You can compare the rendered time across the different browsers and further drill-down to particular a browser to identify which application pages are associated with the highest rendering time for that browser.

For example, you can select Google Chrome and see the corresponding rendering times for the different URL pages for a particular application.

End-user experience

End-user experience can be analyzed by looking at metrics such as load time and render time. Higher load times and render times create a negative end-user experience.

To view the render time and load time for the URLs in an application, navigate to Analytics > Web Insight > URLs. You can see the list of URLs and their corresponding load times and rendering times in a table or as a graph. You can then tune the corresponding web pages to reduce wait time and improve the overall end-user experience.

Web Insight geomap configuration

Geomaps feature in Citrix ADM displays the usage of web applications across different geographical locations on a map. Administrators can use this information to understand the trends in application usage and for capacity planning.

Geomap provides information about the following metrics specific to a country, state, and city:

  • Total Hits: Total number of times an application is accessed.

  • Bandwidth: Total bandwidth consumed while serving client requests

  • Response Time: Average time taken to send responses to client requests.

Geomaps provide information which can be used to address several use cases such as the following:

  • Region that has the maximum number of clients accessing an application

  • Region that has the highest response time

  • Region that consumes the most bandwidth

Citrix ADM provides you an option to configure geomaps for private IP addresses or public IP addresses.

Configuring geomaps for private IP addresses

To view the web application traffic originating from private IP addresses on the geomap, you must first create private IP address blocks and then enable geo data collection. To create IP blocks, see Creating IP blocks.

Citrix ADM can recognize the location a client belongs to when the client private IP address is added to the Citrix ADM server. For example, if the IP address of a client falls within the range of a private IP address block associated with City A, Citrix ADM recognizes that the traffic is originating from City A for this client.

Configuring geomaps for public IP addresses

Most of the public IP addresses are available in the geo database file that is provided along with Citrix ADM. If you are not able to view the web traffic from a public IP address and the public IP address is not available in the geo-database file, you need to create an IP address block and enable geo data collection. To create IP blocks, see Creating IP blocks.

Creating IP blocks

  1. In Citrix ADM, navigate to Analytics > Settings > IP Blocks, and then click Add.

  2. In IP Blocks, specify the name of the IP block, the starting IP address, and ending IP address in the IP block.

  3. Specify the country, region, and city. You might have to specify the latitude and longitude of the city if it is not already saved in the geo database.

  4. Select Create to finish.

  5. Enable geo data collection. For more information on how to enable geo data collection, see Enabling Geo Data Collection.

Enabling geo data collection

Note: You must enable geo data collection for both private IP addresses and public IP addresses.

  1. In Citrix ADM, navigate to Networks > Instances, and further navigate to your Citrix ADC instance.

  2. Select the instance and from the Actions drop-down list box, select Configure Analytics.

  3. On the Configure Insight page, check Enable Geo data collection for Web and HDX Insight.

  4. You will receive a message that says geo data collection was enabled successfully.

The following image provides a snapshot of the geomap. A geomap shows areas from which public and private traffic is originating.

Note

  • Citrix ADM requires an internet connection to display the GeoMaps for a particular geographical location. Internet connection is also required to export the GeoMap in .pdf, .png, or .jpg formats.
  • As Web Insight traffic requires more than an hour to resolve a GeoMap location, GeoMap data for less than one hour is not displayed.

Processing of the Web Insight traffic by Citrix ADM

By default, Citrix ADM processes the Web Insight traffic for monitoring the web applications and generates the Web Insight reports. If you do not want to monitor the Web Insight traffic, you can disable the processing of the Web Insight traffic. Citrix ADM does not process the Web Insight traffic and you do not see the Web Insight reports.

For example, there are five virtual servers on your managed instance. You have enabled AppFlow and selected Web Insight on all virtual servers. Citrix ADM receives the Web Insight traffic from the virtual servers for processing. If you do not want Citrix ADM to monitor the Web Insight traffic, you can disable the processing.

To disable processing of the Web Insight traffic by Citrix ADM:

  1. Navigate to Analytics > Settings.

  2. In the Settings page, click Enable Features for Analytics.

  3. In the Web Insight Settings, clear the Enable Web Insight checkbox.

    Note: Enable Web Insight is selected by default.

  4. Select OK.
