Accessing the VTS Server

The data in the VTS table is maintained on a server known as the VTS server. The name or IP address of the VTS server is displayed after Server Name, in the top left of the VTS user interface.

You can access the data in the VTS table in any of the following ways:

VTS user interface

You can use the standard functionality in the VTS user interface to access data in the VTS table. For example, you can modify an existing parameter value or add a new value. For details, see Manipulating the Contents of the VTS Table.

The VTS Service Windows service enables UI access to the VTS table. By default, when VTS is installed, VTS Service is set to start automatically. If you experience problems accessing VTS, make sure that VTS Service is started. By default, port 4000 is used for UI access to VTS. For details on changing the default UI access port, see Configuring VTS.

Vuser scripts

Vuser scripts can include API functions that enable Vusers to read and modify data in the VTS table. VTS lets you enable or disable API access to the VTS server. When you enable API access, you must specify the port that Vuser scripts use to access the VTS server. The currently used port is displayed after API Access Port, in the top left of the VTS user interface.

The default API access port is 8888, and a direct connection is needed between the VTS server and the load generator machine. For details on how to change the default API access port, see Configuring VTS.

  • To enable API access to the VTS server, from the Access from Script dropdown list, click Enable.

    In the Enable Script Access dialog box, enter the API access port, and then click Enable.

  • To disable API access to the VTS server, from the Access from Script dropdown list, click Disable.
