Configuration of VmgTcpTrafficTest

This test monitors the TCP protocol traffic to and from a Windows virtual desktop on the cloud, and particularly monitors retransmissions.

The default parameters associated with this test are:

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

  • Specify the nick name of the Cloud Desktops component for which this test is to be configured in the HOST text box.

  • Indicate the port at which the host listens to in the PORT text box. By default, this is NULL.

  • To obtain the ‘inside view’ of performance of the cloud-hosted Windows desktops - i.e., to measure the internal performance of the Windows virtual desktops - this test uses a light-weight eG VM Agent software deployed on each of the desktops. Accordingly, the INSIDE VIEW USING parameter is by default set to eG VM Agent (Windows).

  • The REPORT POWERED OS flag is relevant only for those tests that are mapped to the Inside View of Desktops layer. If this flag is set to Yes (which is the default setting), then the ‘inside view’ tests will report measures for even those Windows virtual desktops that do not have any users logged in currently. Such desktops will be identified by their name and not by the username_on_virtualdesktopname. On the other hand, if this flag is set to No, then this test will not report measures for those Windows virtual desktops to which no users are logged in currently.

  • Since this test runs for a ‘Cloud Desktops’ component, the IS CLOUD VMS flag is set to Yes, by default.

  • Specify the minimum threshold for the number of segments sent/transmitted over the network in the SEGMENTS SENT MIN text box. The default value is 25; in this case, the test will compute/report the Retransmit_ratio measure only if more than 25 segments are sent over the network – i.e., if the value of the Segments_sent measure crosses the value 25. On the other hand, if the Segments_sent measure reports a value less than 25, then the test will not compute/report the Retransmit_ratio measure. This is done to ensure that no false alerts are generated by the eG Enterprise system for the Retransmit_ratio measure. You can change this minimum threshold to any value of your choice.

  • If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

  • Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
