NetScaler Insight Center
is a virtual appliance that collects and provides detailed information about web traffic and virtual desktop traffic that passes through your NetScaler appliances. It has two components:
- Web Insight, which monitors HTTP traffic (web-application traffic) passing through load balancing and content switching virtual servers defined on a NetScaler appliance.
- HDX Insight, which monitors ICA traffic (virtual-desktop traffic) passing through NetScaler Gateway virtual servers defined on a NetScaler appliance.
NetScaler Insight Center collects information about applications from the virtual servers to which the applications are bound as services.
The objective of a NetScaler Insight Center virtual appliance is to retrieve AppFlow logging information for each monitored application, analyze the information, and present it as visual reports.
Note: ICA is a Citrix proprietary protocol used in XenApp/XenDesktop traffic. It is composed of virtual channels. A virtual channel is a bidirectional, error-free connection used for the exchange of generalized packet data between a Citrix host for online delivery (XenApp or XenDesktop) and the Citrix Receiver online plug-in. Connections for sound, graphics, client drive mapping, printing, and end user experience monitoring are a few examples of the virtual channels.
