This subtab shows a graphical overview of the number of installed licenses.
For each type of license, the total number of licenses is shown as a horizontal bar. The orange part of the bar indicates the number of licenses that have been used; the blue part shows how many are available. If you let the mouse pointer rest on any bar, a box shows the precise number of available licenses for the license type in question.
Below the graphic are some data about your installation.
This shows the number of connectors connected with the server.
This shows the date on which the DME license was installed.
This field shows a list of the MAC addresses of the server or servers running DME. For each node in the setup (possibly just one), the MAC address is shown along with the Internet address (inet) by which the node in question can be reached. Node is an expression from clustering, where multiple servers can share the load of running DME. The MAC address of each node in a cluster must be included in the license file (unless you are using the server path only for the license).
This field shows if the current license is valid or not. A license can become invalid if it is tampered with (opened in a text editor and changed), or if it is corrupted or missing from the server.
