👤 Simulate user sessions to proactively identify experience issues
🌐 Monitor NetScaler (ADC) health and configuration integrity

The PRTGPlugins suite empowers IT teams to monitor Citrix XenApp and XenDesktop environments in real time. By bridging gaps left by native tools, these plugins offer enhanced observability across user, server, and network levels. Leveraging PRTG’s robust sensor engine, they deliver high-granularity data without requiring complex setups—making it suitable for both SMB and enterprise environments. Typical deployments remain cost-efficient, with pricing often under €30/month.

🔎 Note: The RDPmonitor sensor output may vary depending on Citrix version. See the Admin Guide for compatibility matrix and configuration notes.

✅ Supported Citrix Versions: From legacy Metaframe 4.x to the latest XenApp/XenDesktop 7.x builds, including Citrix Virtual Apps and Desktops 1912/2203 LTSR editions.

🧩 Modular Architecture: Three Specialized Monitoring Plugins

To ensure deep diagnostics without overloading your monitoring setup, the suite is modular. Each plugin targets a specific domain—optimizing data relevance and sensor efficiency.

Server Performance

Farm-wide CPU, memory, and session metrics
Per-role performance (e.g. StoreFront vs Delivery Controller)
Application enumeration and instance tracking
Error and logon issue tracing
ICA session quality and latency statistics
HDX channel-specific performance (USB, printing, video)

User Session Simulation

Scheduled logon simulations from test clients
Logon, launch, and session startup time tracking
Screenshot-based verification (e.g. application launch)
Alerts based on thresholds or timeouts

NetScaler Monitoring

Monitors active sessions and SSL offloading performance
Alerts for certificate expiry and SNI issues
Visibility into load balancing, failover, and gateway status
Instant detection of configuration drift and HA mode changes

🔍 In-Depth: Citrix Session Monitoring

Citrix Session Monitoring with PRTG Plugins

⭐ Key Features Overview

Session Performance Monitoring with Screenshots & History – Track every stage of the user session, complete with visual documentation for troubleshooting and proof.
Citrix/XenApp Health Monitoring – Ensure the entire virtual app infrastructure is operating reliably under expected load and response times.
License Server Usage Monitoring – Monitor available vs. consumed license pool to forecast needs and avoid service denial.

📌 NOTE: This plugin operates in direct mode to ensure session simulations occur exactly as a user would experience. Therefore, the probe must have direct network access to all target publishing servers.

🖥️ Session Monitoring Details

🔍 Why Session Monitoring Matters

Citrix Session Monitoring gives IT teams visibility into the actual user experience, not just backend server stats. By simulating real sessions and capturing login times, application launches, and even screen views, administrators can:

🎯 Proactively detect performance issues – Spot slow logons, delayed app launches, or intermittent session drops before users complain.
📸 Provide forensic evidence – Session screenshots offer visual proof of issues or behavior for troubleshooting or audit purposes.
📊 Measure service quality – Quantify logon durations, session lengths, and ICA responsiveness to improve SLAs and capacity planning.
💬 Reduce support tickets – By identifying errors (like app failures or stuck logins) before users report them, you save time and reputation.
🧠 Understand user experience holistically – From the moment a session begins to logout, every step is accounted for, enabling full-stack optimization.

ICA connection time – Measures time to establish a session channel.
ICA login time – Detect delays during credential verification and profile loading.
Published Application Tracking:
- Launch time with recording – Records how long it takes to start the app, with visual log.
- Screenshot saving – Captures real user views at session start.
- History view – Browse session snapshots for forensic or UX reviews.
Session logoff time – Detects abnormal delays in closing sessions cleanly.
Error count – Provides a quick indicator of session reliability over time.

🌐 In-Depth: Citrix NetScaler Monitoring

Citrix NetScaler Monitoring with PRTG Plugins

🌐 NetScaler Base Monitoring Sensor
This foundational sensor replicates and extends the core information provided by the native NetScaler Dashboard—within the unified PRTG environment. It consolidates resource stats, session metrics, and load distribution without requiring ADC GUI logins. Use Case: Ideal for real-time overview and integrating NetScaler into NOC dashboards.
🔐 NetScaler Certificates Monitoring
Continuously monitors all installed SSL certificates on your NetScaler instance. Each cert is listed by name and remaining validity (in days). A dedicated alert channel highlights the certificate with the fewest days remaining to prevent surprises from expired certs. Why it matters: Ensures compliance and prevents service disruptions due to expired SSL certificates.
📶 Load Balancing Virtual Servers Monitoring
Monitor the operational state of each NetScaler load balancing virtual server, including: Effective state (e.g., UP/DOWN) Current operational status Health score and availability Traffic distribution metrics This sensor uses PRTG lookup tables to deliver readable health statuses (e.g., degraded, optimal, failed).
🚪 Gateway Virtual Servers Status Monitoring
Gathers health data for Gateway Virtual Servers and tracks concurrent AAA user sessions. This is critical for environments using NetScaler as a secure remote access or VPN solution. Benefits: Helps detect overload, unauthorized access patterns, or failed login surges in real time.
⚙️ NetScaler Configuration Changes Monitoring Configuration drift is one of the leading causes of unplanned outages. The NetScaler Configuration Sensor helps enforce configuration hygiene through three modes:
🔒 Monitoring NetScaler Modes Lock critical settings (e.g., HA, L3 modes, routing) and receive alerts if they are changed. This creates a policy-driven approach to configuration management.
💾 Monitoring Unsaved Configurations Alerts administrators when configuration changes remain unsaved past a customizable threshold. This feature is especially useful in HA environments where config sync failures may occur.
🗂 Monitoring Latest Backup Age This lightweight sensor keeps track of the most recent configuration backup by file name and age. Admins can define warning or error thresholds (e.g., no backup in 7 days) to enforce backup policies. Why it's useful: Easily integrate NetScaler backup compliance into overall infrastructure audit checks.
