\"EliminateDaniel Feller, a lead architect at Citrix, recently posted a couple of very interesting articles relating to troubleshooting Citrix logon issues. These blogs highlight challenging Citrix issues and how to go about locating the root cause of these issues.<\/p>\n

Troubleshooting Citrix Problems is Very Challenging<\/h2>\n

The first example<\/a> concerns logon times that reached 100+ seconds when users logged onto Citrix Virtual Apps. In this case, Citrix Director reported that VM start, GPO processing, logon script execution and interactive session time all took over 20 seconds. So where is the root cause of the slowness?<\/strong><\/p>\n

Citrix Director reporting a slow logon. VM start, GPO processing, logon script execution and interactive session time all were 20 seconds or more.<\/div>\n

Troubleshooting is often very time consuming and involves a process of elimination. In this case, one can deduce that since the user logon eventually succeeded, the Citrix delivery infrastructure components \u2013 StoreFront, Delivery Controller, SQL Server \u2013 should have been available and operational. Since the user connected to the Citrix site from an internal end-point in the network, the Citrix ADC\/NetScaler could not have caused the problem (only external accesses would have used the Citrix ADC). And since the user did not notice any slowness after the logon succeeded, the virtual desktop that the user connected to during the session was not likely to because of the issue. Ultimately, the problem was narrowed down to excessive memory utilization on the Citrix Delivery Controller. Since the Citrix Delivery Controller is a central coordinator during logon and session establishment, a resource bottleneck resulted in an unusually high Citrix logon time and many of the stages of the logon process showed slowness.<\/p>\n
