For customers on the Current Release path for Citrix Virtual Apps and Desktops, one of the best features available to you is the ever-growing list of cool stuff that Director Introduces.
A few features that I find have not gained enough love, given how important and awesome they are, are listed below with some real life data against them:
Profile Management Drill Down. No kidding, as I was writing this post, I was working with a customer who just upgraded to 1906 from LTSR 7.15. Their profile load times (showing at 40 seconds for one user), took about 5 seconds in Director to identify the problem. Two guesses as to what was going wrong…
Interactive Session breakdown and Drill Down. Interactive session drill downs are one of the most elusive and frustrating components to troubleshoot in an environment, as it’s like a dirty pit of doom where all the nasties seem to land. We now have a bit more ability to drill down and identify the specific components within the Interactive Logon as per below.
By default, the detail below looks good, however, it isn’t quite functioning as one would expect, as we are missing the breakout of the shell and Userinit phases.
The trick here is to enable process audit tracking on the VDA’s via Group Policy:
Once in play, we can see the appropriate breakout of Shell and Userinit:
Client-Side Extension Breakdown and Drill Down. This is a huge win and something I am quite passionate about–the identification and annihilation of rubbish CSE (Client-Side Extension) problems–typically Group Policy Preferences and Folder Redirection. Previously, we have had to leverage tools like ControlUp’s Analyze Logon Duration Analysis PowerShell-based SBA written by the ridiculously clever Guy Leech, however, we now have this data visibility on the fly via Director natively–very cool.
Below we can see a session showing a 47-second logon duration (nasty):
It doesn’t take long to drill down and identify that Group Policy Drive Maps are to blame for this horrible crime:
And when we drill down into detailed information, we can see exactly which policy is to blame:
What I am really impressed with is that the phases are accurately lining up these days, we can see that dodgy CSE extensions and GPO processing are having a direct hit on the Interactive Session times:
Fix the offending policy, and the results are obvious:
Session Startup Analysis. The new session startup analysis breakdown is extremely impressive. Not only are we monitoring how long it takes to log on, but now we have a breakdown into how long it took the actual session to establish and where the delays where–Dodgy DNS, Dodgy Active Directory, Dodgy ICA file generation–all things that are typically invisible, yet directly impact the user-perceived logon times and are not provided in a single pane of glass. Extremely impressive progress.
Desktop and Application probing. A proactive mindset vs. a reactive mindset is often the make or break difference for teams managing EUC platforms. If you can see a problem before it hits your user base, then you are well and truly ahead of the game. There are entire toolsets available in the industry to put you ahead of the game entirely, however, for platinum or cloud customers, Application and Desktop probing is available to you out of the box, allowing for a basic session launch of key applications or desktops, and appropriate alerting and reporting should these fail. Proactive fun at its best.
A really cool byproduct of this technology is that you actually have a tool that can not only monitor the number of sessions that will launch, but also an out-of-the-box native capability to address the first session of the day logon lag. I previously wrote a script utilizing the free (and awesome) ControlUp Logon Simulator to address this, which successfully runs in numerous environments with success. Now you have a tool that is in build to achieve the same – Probe the machine (ha!), perform the logon, confirm the health and warm up that VDA for the next user. Win. Win. Win.
It can be hard to keep up with the amount of development work and feature releases that come out with each CR release, so below is a nice table listing all features since the LTSR 7.15 release:
|Feature and Version||Details and Cool Factor|
|1906: Session Auto Reconnect||The Sessions page on the Trends tab now includes information about the number of auto reconnects. Auto reconnects are attempted when the Session Reliability or Auto Client Reconnect policies are in effect. The auto reconnect information helps you view and troubleshoot network connections having interruptions, and also analyze networks having a seamless experience. The drilldown provides additional information like Session Reliability or Auto Client Reconnect, time stamps, Endpoint IP, and Endpoint Name of the machine where the Workspace app is installed. This feature is available for Citrix Workspace app for Windows, Citrix Workspace app for Mac, Citrix Receiver for Windows, and Citrix Receiver for Mac.

This feature is available on Delivery Controller version 7 1808 or later and VDAs 1808 or later. The Interactive Session drilldown bar shows the time duration for the current session only. For more information, see Diagnose user logon issues.|
|1808: Logon Performance – GPO drill-down||The Logon Duration panel in the User and Session details view contains the GPO (Group Policy Objects) duration. This is the total time taken to apply the GPOs on the virtual machine during the logon process. Now, you can see the drill down of each policy applied as per CSEs (Clients-Side Extension) as a tool tip in the GPO bar. For each policy application, the drill down displays the status and the time taken. This additional information eases troubleshooting and remediation of issues involving high GPO duration. The time durations in the drill down represent the CSE processing time only and do not add up to the total GPO time. This feature is available on Delivery Controller version 7 1808 or later and VDAs 1808 or later. For more information, see Diagnose user logon issues.|
|7.18: Application probing||This feature automates health checks of XenApp and XenDesktop applications published in a Site, thus improving the user experience. To initiate application probing, install and configure the Citrix Application Probe Agent on one or more endpoint machines. In Director’s Configuration page, configure the applications to be probed, the endpoint machines to run the probe on, and the probe time. The agent tests the launch of selected applications using StoreFront and reports back the results to Director. The probe results are displayed on the Director UI – the last 24-hours’ data in the Applications page and historical probe data in the Trends > Application Probe Results page. Here, you can see the stage when the probe failure occurred–StoreFront Reachability, StoreFront Authentication, StoreFront Enumeration, ICA download, or Application launch. The failure report is emailed to the configured addresses. You can schedule your application probes to run during o -peak hours across multiple geographies. The comprehensive results can help to proactively troubleshoot issues related to provisioned applications, hosting machines or connections before the users experience them. Application probing is available for Platinum licensed Sites. This feature requires Delivery Controller(s) version 7.18 or later. For more information, see Application Probing.|
|7.18: Built-in alert policies||Director now has a set of built-in alert policies for Delivery Groups and Server OS VDAs scope. These policies are displayed in the Director > Citrix Alerts Policy page. Alert notifications are generated on the breach of the default threshold values predefined for these alerts. The threshold values ensure basic optimal performance parameters in the Site and can be edited. The built-in alert policies are created when there is at least one alert target–a Delivery Group or a Server OS VDA defined in your Site. In case you upgrade your Director instance and your Site, the alert policies from your previous Director instance are carried over. Built-in alert policies are created only if no alert rules for the policies exist in the Monitor database. This feature requires Delivery Controller(s) version 7.18 or later. For more information, see Alerts and Notifications.|
|7.18: Health Assistant link||The Machine Details page of an unregistered machine in the Monitoring console now contains a Health Assistant button.
