CGI script parameters

To reference the device, use the following fixed parameters, which are automatically passed to user-defined scripts by TopoViz.

$selected_rows.ServerName

This value defines the name of the ObjectServer that corresponds to the current Network Manager domain. This value is defined in the ncp.domains table when the topology database is created.

$selected_rows.NmosObjInst

This value is a unique identifier for the device. It is equivalent to the ObjectId field in the mainNodeDetails table of the topology database.

$selected_rows.Node

This value is from the ObjectServer. The value is usually equivalent to the IpAddress field in the mainNodeDetails table of the topology database.

These values refer to the device that was selected when the context menu was used. Topoviz uses an HTTP Get request to call the script and passes the above parameters in the URL. The URL is encoded into x-www-form-urlencoded format. Non-alphanumeric characters are converted into the 3-character string %xy, where xy is the two digit hexadecimal representation of the lower 8-bits of the character.
