HDX User Agents Test

Users can connect to applications/virtual desktops using may client devices – the ICA client, web browsers, mobile phones, tablets, etc. Each such client device is called a user agent. Users using certain types of client devices/user agents may be engaged in bandwidth-intensive communication over ICA, scarring the experience of other users to the XenApp/XenDesktop environment. To capture such problem conditions quickly, it would be best to know what types of client devices users are connecting from and how much bandwidth each of these device types are currently consuming. This is exactly what the HDX User Agents test reveals! This test auto-discovers the types of client devices that are interacting with the applications/virtual desktops, and reports the bandwidth usage of each device type. This way, the test leads administrators to those device types that are consuming bandwidth excessively.

Target of the test : Citrix ADM HDX Insight

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each type of client device/user agent users are connecting from

Parameter	Description
Test period	How often should the test be executed. It is recommended that you set the test period to5 minutes. This is because, the Nitro API using which the eG agent collects metrics from HDX Insight, is capable of capturing only the performance data related to the last 5 minutes.
Host	The host for which the test is to be configured.
Insight Username, Insight password, and Confirm password	To connect to HDX Insight and collect the metrics it captures, the eG agent needs to be configured with the credentials of a user with read-only permissions to HDX Insight. Type the name of this user against insight Username and the password of this user against Insight password. Then, confirm the password by retyping it in the Confirm password text box.
SSL	By default, HDX Insight is not SSL-enabled. This is why, this flag is set to No by default. If it is SSL-enabled, then change this flag to Yes.
DD Frequency	Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Avg bandwidth	Indicates the rate at which data is transferred over the ICA sessions launched from this device type.	Mbps	Ideally, the value of this measure should be low. A high value indicates excessive bandwidth usage by users connecting from the device type. Compare the value of this measure across device types to know users using which type of device are engaged in bandwidth-intensive communication over ICA.
Bandwidth consumed in the last measure period	Indicates the amount of data (in MB) transferred to / received from this device type 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 device type.
