Businesses expect seamless Citrix services for their users, and this means 24x7 service availability, great response times and uninterrupted service delivery. To achieve this, Citrix administrators need to monitor the user experience. Just looking at CPU, memory, and disk usage trends is no longer sufficient. By monitoring the user experience, administrators can see the actual response being seen by Citrix users.
A popular way to monitor Citrix user experience is using the simulation of a user accessing the Citrix farm. The results of periodic simulation highlight whether the Citrix farm is working well and its responsiveness. By checking the status of the Citrix services even when no users are actively accessing the Citrix farm, simulation of user sessions provides proactive indicators of potential problems.
eG Enterprise is a purpose-built Citrix performance monitoring, diagnosis and root cause analysis solution that provides deep performance insights for XenApp, XenDesktop and all components in the Citrix stack. To provide a complete view of Citrix performance, eG Enterprise embeds the ability to monitor real user sessions as well as simulated sessions.
eG Enterprise includes two synthetic simulation approaches for Citrix environments:
In both approaches, the success of the simulation, the overall time taken for the simulation, and the time taken to perform each step are recorded. These results are then analyzed to determine when and how to alert administrators to potential Citrix performance issues.
A typical example of synthetic monitoring would be simulating a user logging into an SAP application, accessing records, updating information, closing the application, and finally, logging out of the session.
When an administrator is looking to understand if Citrix logons are slow and why, a Citrix logon simulator is helpful. However, there are many other aspects to Citrix user experience beyond the logon. If an administrator needs to look at the performance of a client application launched through Citrix in more detail, Citrix logon simulation is not enough.
For example, an administrator may want to see if an SAP client published on Citrix can be launched successfully, if a user is able to logon to the SAP application, query the inventory, update a record, and logout of SAP in a timely manner. To address this requirement, Citrix full session simulation is needed.
|Key questions Citrix administrators can answer using full session simulation:|
With the recorded Citrix session simulation, you can:
Complement simulated session performance metrics from eG Enterprise with real user logon and session performance metrics obtained from Citrix Director/EdgeSight for complete performance insight.
eG Enterprise supports both real user monitoring and synthetic monitoring of Citrix XenApp and XenDesktop sessions. Both approaches are complementary to one another and, together, present actionable insights that Citrix administrators need for troubleshooting and performance fine-tuning. Here are some key differences between the two approaches:
|Real User Monitoring||Synthetic Transaction Monitoring
(Using Full Session Simulation)
|Tracks performance and user experience of real user sessions and transactions||Captures performance and user experience of simulated user sessions and transactions|
|Passive monitoring technique: Continuously monitors real user activity||Active monitoring technique: Only runs when a synthetic test is created and executed|
|Monitoring data is captured from the server side (XenApp servers and XenDesktop VMs)||Monitoring data is captured from transactions run on specific nodes from any central or remote location|
|Captured results always depend on actual, real user workload||A pre-defined workload is repeatedly imposed on a target endpoint|
|Is a direct measure of real user experience; only available when users are actively logged on||Is a measure of user experience even when real users are not active|
