Citrix Web Operating Systems Test
When measuring user experience with web applications, it would also help administrators to know which client operating systems are widely used for accessing the applications and whether bandwidth usage and page rendering is impacted by the operating system in use. This way, administrators will be able to identify bandwidth-intensive operating systems and those that are inherently slow in rendering web pages. Users may then be discouraged to use such operating systems. The Citrix Web Operating Systems test enables administrators make such recommendations. This test auto-discovers the operating systems used by clients and reports the requests received, bandwidth consumed, and page rendering time per operating system. In the process, the test points to the most popular, the most bandwidth-intensive, and the slowest (in terms of page rendering) operating systems.
Target of the test : An AppFlow-enabled ADC Appliance
Agent deploying the test : A remote agent
Outputs of the test : One set of results for every client operating system
Parameter | Description |
Test period |
How often should the test be executed. It is recommended that you set the test period to 5 minutes. This is because, the eG AppFlow Collector is capable of capturing and aggregating AppFlow data related to the last 5 minutes only. |
Host |
The host for which the test is to be configured. |
Cluster IPs |
This parameter applies only if the ADC appliance being monitored is part of a ADC cluster. In this case, configure this parameter with a comma-separated list of IP addresses of all other nodes in that cluster. If the monitored ADC appliance is down/unreachable, then the eG AppFlow Collector uses the Cluster IPs configuration to figure out which other node in the cluster it should connect to for pulling AppFlow statistics. Typically, the collector attempts to connect to every IP address that is configured against Cluster IPs, in the same sequence in which they are specified. Metrics are pulled from the first cluster node that the collector successfully establishes a connection with. |
Enable Logs |
This flag is set to No by default. This means that, by default, the eG agent does not create AppFlow logs. You can set this flag to Yes to enable AppFlow logging. If this is done, then the eG agent automatically writes the raw AppFlow records it reads from the collector into individual CSV files. These CSV files are stored in the <EG_AGENT_INSTALL_DIR>\NetFlow\data\<IP_of_Monitored_ADC>\webappflow\actual_csv folder on the eG agent host. These CSV files provide administrators with granular insights into the web appflows, thereby enabling effective troubleshooting. Note: By default, the eG agent creates a maximum of 10 CSV files in the actual_csv folder. Beyond this point, the older CSV files will be automatically deleted by the eG agent to accommodate new files with current data. Likewise, a single CSV file can by default contain a maximum of 99999 records only. If the records to be written exceed this default value, then the eG agent automatically creates another CSV file to write the data. If required, you can overwrite these default settings. For this, do the following:

Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Hits |
Indicates the number of requests received from clients running this operating system. |
Number |
Compare the value of this measure across operating systems to identify the most popular operating system. |
Bandwidth |
Indicates the total amount of data received from clients running this operating system. |
KB |
Compare the value of this measure across operating systems to know which operating system has been consistently consuming more bandwidth than the rest. |
Avg render time |
Indicates the elapsed time, from when clients running this operating system start to receive the first byte of a response until either all page content has been rendered or the page load action has timed out. |
Msecs |
Compare the value of this measure across operating systems to know which operating system is taking too much time to render web pages. |
