Quickly Troubleshoots “Citrix is Slow” Complaints

“Citrix gets a bad reputation as being blamed for everything, but the underlying issue rarely has anything to do with Citrix. Goliath provides end-to-end visibility across the entire Citrix delivery infrastructure and enables us to quickly isolate root cause of performance issues, identifying who in IT can help resolve the issue quickly.” – Vitaly Petrovsky, Manager of Enterprise Applications, Maimonides Medical Center

Increase in Remote Workers Due to COVID-19

Maimonides Medical Center is a non-profit hospital located in Brooklyn, N.Y. When COVID-19 hit, many on their team were instructed to work from home. Vitaly Petrovsky, Manager of Enterprise Applications, realized that with an increase in remote workers, he needed a solution that would more effectively monitor and troubleshoot their Citrix infrastructure, which was delivering medical staff access to clinical and other applications.

Even prior to COVID-19 Petrovsky shared that, “Citrix gets a bad reputation as the root cause of all slow logons or session performance issues. The reality is many of the underlying issues just surface themselves when users logon to Citrix, and Citrix is not at fault.” When many on Maimonides’ medical staff started working from home, Petrovsky recognized the number of “Citrix is Slow” complaints were only going to increase.  He needed a tool that the support team could use to prevent calls being falsely escalated to his 3rd line engineers.

“I had looked at Citrix native tools, like Director, but it lacked the granularity in its metrics to isolate root cause of poor performance issues. It also didn’t provide historical data to look back at past trends,” said Petrovsky. End users don’t typically report issues in real-time, so he needed the ability to look historically to understand how performance has changed or find exactly when an issue did occur.

Finally, Petrovsky said when he started looking at monitoring tools he “needed a solution that would proactively look for issues. My team can’t just be reactive waiting to hear end users complain. We need to prevent issues from occurring before our medical team even logs into Citrix to access their clinical applications.”


Purpose-built Monitoring and Troubleshooting Tool with Embedded Intelligence & Automation

When COVID-19 hit, Petrovsky knew he needed a solution that not only delivered broad and deep metrics for troubleshooting, but also had intelligence and automation embedded so that the support team and his infrastructure team could utilize it for troubleshooting.

“We selected Goliath Technologies as it offered us a single pane of glass along with deep and broad metrics to isolate the root cause of end user performance issues beyond Citrix. It easily identified if slow performance could be attributed to a bad network drive mapping inside of a group policy or to slow connection speed with a user working from their home WiFi network,” shared Petrovsky. He asked his support team to learn how to use the tool by attending a webinar and virtual training, and they have found it beneficial when verifying end users are experiencing slowness and isolating the root cause to pass along to the appropriate team to fix. This helps reduce the number of escalations to 3rd line support.


As a result of using Goliath, Maimonides has been able to more quickly troubleshoot performance issues both for their remote medical staff and those on-site at the hospital. This has not only saved his team significant time but has also increased overall clinician satisfaction when accessing clinical apps.

Example #1: Troubleshooting Slow Performance for the Home Worker

With everyone working from home, Maimonides’ support team was seeing an increase in calls about slow performance. Using Goliath, the team could easily view an end user’s session and see that their local network connection was slow (Image 1). They could then share the data with the user, highlighting the slow connection speed and either ask if someone else was consuming bandwidth (maybe streaming Netflix) or recommend they upgrade their internet speed in order to improve performance. This saved a lot of time trying to hunt down answers to complaints that had nothing to do with the Citrix environment, but instead, the user’s home office.

Example #2 Troubleshooting Slow Logons

Petrovsky shared, “We were getting sporadic complaints from some users that applications launching in Citrix were crashing. It wasn’t consistent and while some applications worked, others did not. Before, trying to troubleshoot these sporadic issues was difficult as a pattern could not be identified to understand what was going on.”

With Goliath, Maimonides was able to drill down into the end user session display and verify that the user was experiencing long logon processing time.  From there, they could see that the majority of logon time was being consumed at the group policy level. As they dug further, they identified that there was an old network drive that no longer existed mapped to their Active Directory group. As a result, when they logged on Citrix would time out looking for that drive. As soon as they removed the drive from the AD group, logon times went back up (Image 2).

“Goliath gives us the granular visibility we need to troubleshoot issues quickly,” said Petrovsky.

The other value that Goliath delivered is the visibility into logon times historically.

One thing they discovered using Goliath is that when they were running on Linux OS vs. Microsoft, there were significantly faster reconnects. It enables them to go back to Citrix who confirmed running on Linux is natively faster than Microsoft. This now has Maimonides exploring how they can potentially use more with Linux to improve logons.

When Petrovsky sums up the value that Goliath has delivered, he states “Goliath offers us a single pane of glass to view everything, helping us quickly troubleshoot performance problems for our staff. It is easy to use and offers historical insights we never had visibility into before.”
