Slow logons, laggy VDI sessions, and poor Horizon performance are common pain points IT admins face frequently. When Omnissa Horizon environments slow down, both end-users and IT teams feel the pressure—users grow frustrated while admins struggle to troubleshoot without complete visibility.
To uncover the real-world Horizon issues admins face, we turned to Reddit forums like r/VMwareHorizon, r/sysadmin, and r/Citrix, where IT professionals openly share their Horizon troubleshooting struggles. From login delays to fragmented monitoring tools, these conversations highlight the top Horizon challenges.
In this blog, we highlight the top 7 Omnissa Horizon issues—straight from IT communities—and explain how eG Enterprise, a leading digital workspace monitoring solution, helps resolve them with actionable insights.
1. Slow Logons & VDI Session Slowness in Omnissa Horizon
The issue | Source: r/VMwareHorizon (August 2021): Admins on Reddit report Horizon logon times of 80–200 seconds, with inconsistent performance across sessions.
How eG Enterprise helps: eG Enterprise breaks down every stage of the logon process—from brokering to GPO processing, profile loading, and application initialization. Thus, enabling admins to pinpoint exactly where delays occur. By isolating whether the slowness is tied to VMs, domains, profile servers, or third-party tools like FSLogix and App Volumes, IT teams gain the leverage to target corrective actions while ignoring false alarms. This reduces guesswork and helps deliver faster, more consistent logon experiences through granular insights.
2. Microsoft OS Patches Causing Horizon Logon Delays
The issue | Source: r/VMwareHorizon (Dec 2022): Admins traced performance degradation to Microsoft update KB5021233, causing logon times to increase by over 45 seconds.
How eG Enterprise helps: eG Enterprise uses historical baselines for easy spotting of performance deviations immediately after patching. It correlates patch-level changes with logon and session metrics. This helps admins determine if a new update is the root cause of slowness. Additionally, the proactive visibility helps IT teams roll back or optimize patches before end-users are impacted.
3. Troubleshooting Horizon Performance: Proving It’s Not the Network
The issue | Source: r/sysadmin (Dec 2022): Admins struggle to demonstrate whether performance issues stem from network latency or backend problems—often causing friction with other teams.
How eG Enterprise helps: By providing hop-by-hop network telemetry, eG Enterprise pinpoints where issues begin. It correlates insights across VMs, connection servers, backend storage, and network paths for complete clarity. eG Enterprise’s visual topology maps allow IT teams to prove—or disprove—network involvement in seconds. This eliminates finger-pointing and fosters quicker collaboration between teams.
4. Fragmented Monitoring Tools & Alert Overload in Horizon Environments
The issue | Source: r/sysadmin (Dec 2022): Admins found the now defunct Horizon Reach limited and ended up relying on multiple siloed tools across teams—causing alert fatigue and lack of centralized insight.
How eG Enterprise helps: eG Enterprise unifies monitoring across Horizon, supporting infrastructure, and virtual desktops within a single console. Instead of juggling multiple dashboards, admins get one view of the entire digital workspace. Smart alerting and automated root cause analysis cut through the noise, helping teams focus only on critical issues that truly need attention.
5. Limited Native Horizon Metrics for VDI Troubleshooting
The issue | Source: r/Citrix (May 2024): Horizon’s built-in metrics are insufficient for diagnosing session slowness, performance dips, or infrastructure strain.
How eG Enterprise helps: eG Enterprise extends visibility far beyond native Horizon metrics, covering VDI sessions, protocol health (Blast, PCoIP), hypervisor load, storage performance, and even app-level behavior. By correlating these metrics in real-time, admins can move from reactive firefighting to proactive problem prevention. This comprehensive view ensures no blind spots in the troubleshooting process.
6. Poor Remote Experience with Horizon Client vs Citrix
The issue | Source: r/sysadmin & r/Citrix (Mar 2023 & May 2024): End-users complain of laggy sessions, mouse delays, and VOIP stutters—even on good hardware.
How eG Enterprise helps: eG Enterprise continuously monitors real user experience metrics like keyboard/mouse latency, screen refresh rates, and packet loss. It helps IT teams quantify UX degradation and map it back to client settings, protocol configurations, or infrastructure bottlenecks. This evidence-driven approach ensures admins can resolve remote experience issues quickly and confidently.
7. Uncertainty After Broadcom Acquisition: Evaluating Horizon Alternatives
The issue | Source: r/Citrix (May 2024): Admins express hesitation about Omnissa Horizon’s roadmap and are seeking alternatives—many of which have their own limitations.
How eG Enterprise helps: As a vendor-agnostic platform, eG Enterprise supports Horizon alongside Citrix, Microsoft AVD, and other workspaces within a single pane of glass. This ensures IT teams retain full visibility during platform transitions or when running hybrid environments. By providing continuity and consistency, eG Enterprise future-proofs digital workspace monitoring against uncertainty.
