Is there a possibility to get on a Fabric an overview of the Fabric Size?

With show virtual-ist I can see if the device is working with Virtual IST

show isis interface shows me a working ISIS Interface. To have an understanding of which ports my Fabric is connecting.

I am not sure, if i understand your Q correctly, but did you use "show isis spbm nick-name" ? This would display your all fabric nodes in a given ISIS area ; so in a single-area setup in fact alll fabric nodes. The output also has a column for Virtual-BMAC, so one would easily be able to find out, which nodes are setup as VIST pairs. If your node is a Muulti-Area Boundary node, the command above would evenn display you all nodes in both Home and remote ISIS areas. See example bewlo:
