Business Service Management (BAC/BSM/APM/NNM)

More than everything monitoring, BSM provides the means to determine how IT impacts the bottom line. Its purpose and main benefit is to ensure that IT Operations are able to reactively and proactively determine where they should be spending their time to best impact the business. This covers event management to solve immediate issues, resource allocation and through reporting performance based on the data of applications, infrastructure, networks and from third-party platforms. BSM includes powerful analytics that gives IT the means to prepare, predict and pinpoint by learning behavior and analyzing IT data forward and backwards in time using Big Data Analytics applied to IT Operations.

How to Proactively Monitor Virtual Desktop Infrastructure (VDI)

This blog was authored by Rotem Steuer, my esteemed colleague from HP Research & Development.



XenApp & XenDesktop Application Performance Monitoring

Citrix XenApp and XenDesktop allow – via the usage of the Independent Computing Architecture (ICA) protocol - remote activation of the application. This activation may be considered as an advanced form of the known windows remote desktop without the known windows remote desktop limitations and with the ability to activate only a single application in a remote manner (though the Remote Application may also be the entire “Desktop”).


The Following Diagram Illustrates a typical Citrix XenApp deployment:




As we can see – real users interact directly with the XenApp and XenDesktop Servers with the remote application activation. The use of HP RUM allows organizations to monitor those sessions and even view the monitoring in aggregation groups of Application and User names.


The Following Screen shot illustrates:




With the use of HP RUM we can identify Application Activation problems related to the XenApp Servers, specifically:

-       Remote Application latency

-       Specific users (and users groups) response time issues

-       Availability which relate to remote application or to specific user / user group


Monitoring a Web Application on top of XenApp & XenDesktop Solutions

A common use case scenario is accessing a web application via the use of Citrix XenApp and XenDesktop Remote Browser (or a Browser) Application.

This scenario is popular since it provides IT with a single point of management in the aspects of Security, customization of browser plug ins (.net  / jvm / active versions) – and web application configuration (proxy, url etc).


The Following diagram illustrates adding a Web Application to Citrix XenApp:




However, since the XenServer performs the actual access to the Web Server  we cannot distinguish which web application action was performed by which real user.

For example, according to the above diagram if user 1 (with client ip performs actions on the web application and if at the same time user 2 (with client ip perform actions on the same web application naive monitoring of the web application will discover a single user (with client ip
which perform several actions on the same web server.


Citrix XenApp and XenDesktop  now introduces challenges to Web Monitoring that must be addressed in application performance monitoring.  For example  we can no longer identify a problem which relate to an end user group like  bad performance to specific geographic location and/or lack of permission to specific end user group.


HP RUM  Citrix monitoring solutions enable organizations  to track down real user login name and Client IP even if the actual monitored application is a web application activated by XenApp / XenDesktop.


The Following screen shot illustrates how HP RUM can help monitor Citrix XenApp & XenDesktop web applications:
