Measures reported by CbrIcaStatsTest
Branch Repeater includes ICA acceleration powered by HDX IntelliCache and HDX Broadcast technologies to optimize virtual application delivery. HDX IntelliCache optimizes delivery across multiple Citrix® XenApp™ and Citrix® XenDesktop™ sessions by locally caching and de-duplicating transmission of common graphics and data within the ICA protocol. HDX Broadcast, on the other hand:
- Optimizes the flow of XenDesktop and XenApp ICA® traffic across multiple connections in a branch by sensing and responding to network and traffic conditions;
- Reduces XenDesktop and XenApp ICA bandwidth consumption by applying optimal compression techniques based on traffic characteristics, infrastructure capabilities and network conditions;
- Orchestrates with XenDesktop and XenApp to participate in the ICA session and provides intelligent acceleration of the ICA protocol by sensing and responding to the network and traffic conditions;
- Allows administrators to define rules that set which types of application traffic or ICA workflows receive the highest priority.
But, how can administrators determine the adequacy of these instrumentations? What if, even after having configured the branch repeater with acceleration rules, administrators continue to receive user complaints related to slowness in ICA connections to virtual desktops? To handle such situations, administrators should keep an eye on the accelerated traffic for each ICA application, measure the throughput of the traffic, and accurately identify those applications for which ICA traffic may have to be regulated further to reduce bandwidth consumption and optimize throughput. To achieve this, administrators can use the CbrIcaStatsTest test.
This test monitors the accelerated traffic to and from each ICA application, reports how effectively the branch repeater performs ICA acceleration, and in the process, accurately pinpoints areas for improvement - i.e., points to those applications for which the ICA traffic can be accelerated further by fine-tuning compression and QoS rules in the branch repeater.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Sent_Volume |
Indicates the rate at which data was transmitted by this ICA application. |
KB/Sec |
If the value of these measures is well-within the bandwidth limit set for your WAN links, it indicates the efficiency of the branch repeater in maximizing throughput and minimizing bandwidth consumption.
If the value of these measures indicates excessive bandwidth usage, then you may have to compare the value of these measures across ICA applications to know which application is consuming the maximum bandwidth. You should then alter the priority of the traffic and ICA workflows related to this application to reduce bandwidth usage. |
| Received_Volume |
Indicates the rate at which data was received by this ICA application. |
KB/Sec |
| Sent_Ratio |
Represents the sent volume of this ICA application as a percent share of the total volume of traffic sent by all ICA applications. |
Percent |
Compare the value of this measure across applications to identify bandwidth-intensive applications, and to understand how ICA traffic priorities should be set in the branch repeater. |
| Received_Ratio |
Represents the received volume of this ICA application as a percent share of the total volume of traffic received by all ICA applications. |
Percent |
Compare the value of this measure across applications to identify bandwidth-intensive applications, and to understand how ICA traffic priorities should be set in the branch repeater. |
