Measures reported by CtxNsIsIcaChnlTest

ICA traffic 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. One of the important motives behind ICA traffic monitoring is to understand how much bandwidth is being consumed by each channel and in the process identify the most bandwidth-intensive channel. The CtxNsIsIcaChnlTest test helps administrators with this.

This test monitors the ICA traffic handled by each channel and leads administrators to that channel which is consuming bandwidth excessively. The insights provided by this test help administrators in understanding how the NetScaler appliance needs to be fine-tuned to optimize bandwidth consumption.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Avg_bandwidth Indicates the rate at which data is transferred over this virtual channel. Kbps Ideally, the value of this measure should be low.

A high value indicates excessive bandwidth usage by a virtual channel.

Compare the value of this measure across channels to know which channel is consuming bandwidth excessively.

Total_bytes Indicates the amount of data (in MB) transferred / received over this virtual channel during the last measurement period. MB A consistent increase in the value of this measure over time is indicative of excessive bandwidth usage by a virtual channel.
