Many organizations are looking to upgrade their approach to desktop management, by moving away from individual desktops with hard-coded combinations of OS, apps and user settings, and managed one-by-one on an ongoing basis. Virtual desktop technologies offer organizations significant usability, performance, and cost benefits. Citrix's XenDesktop technology offers an industry leading framework for provisioning and delivery of desktops to users.
The core component of the XenDesktop desktop virtualization infrastructure is the Desktop Delivery Controller (DDC) – the connection broker that manages the assembly of users’ virtual desktop environments, and brokers connections between users and their virtual desktops. So critical is the DDC to the virtual desktop service that even the slightest aberration in its performance can significantly impact the user experience. In an era where time is money, the penalties/losses associated with slowdowns or service outages are often significant. At the same time, it is important to know when a problem is being caused by the DDC and when it is resulting from issues with other parts of the virtual desktop infrastructure such as the network, the storage tier, the virtualization platform, etc. Hence, what virtual desktop administrators need is an end-to-end monitoring solution that monitors every layer of every tier of the VDI infrastructure and can offer early warning indicators of problems in any of the VDI tiers.
Various types of reports available in the eG Reporter provide powerful insights into an IT infrastructure's performance.
A single eG agent deployed on the ‘master server’ in a Xen DDC farm is all that is required for monitoring any Xen DDC in that farm. The eG XenDesktop monitor discovers the controllers in the farm and their individual state. It also monitors the connectivity between the controllers and the license server, the datastore, and the virtualization platform. Virtual desktops are often organized as different desktop groups. The eG XenDesktop monitor discovers these desktop groups and tracks the simultaneous usage levels of desktops in each group, so that it can identify times when the DDC could be running out of available desktops.
With its unique single agent technology, eG Enterprise offers monitoring and reporting beyond the Xen DDC. eG agents monitoring the virtualization platform (vSphere, XenServer, Hyper-V, etc.) provide a unique 360 degree view of each and every virtual desktop, highlighting the amount of physical resources each desktop is consuming as well as the individual application processes that are responsible for the resource utilization. Specialized monitors are also available for the network devices, access gateway, web interface, license servers, profile servers, and other components of the virtual desktop architecture.
eG Enterprise analyzes the metrics from every tier of the virtual desktop infrastructure in real-time and compares the metrics with automatically generated baselines to determine the problem areas. A patented automatic root-cause diagnosis engine analyzes the problem areas and based on inter-application dependencies, accurately points administrators to the layer where the problem actually originated – this keeps the help desk focused on the problem source rather than the problem effects. The root-cause, once identified, is instantly intimated to the administrator via the eG monitoring console, email, SMS, or pager, thereby compelling the user to quickly initiate corrective measures. Faster problem resolution ensures a high uptime for the virtual desktop service.
eG Enterprise also offers a wealth of reports that are critical as administrators look to scale their desktop virtualization deployments. By analyzing the resource usage levels with load, administrators can determine how the infrastructure needs to be sized for future rollouts. Analysis of peak usage times, identification of top resource consuming users, load analysis across tiers, etc. can all be done using eG Enterprise’s web-based reporting capability.
