Hi Alex,
You can log the capacity of the entity server by selecting the block in the model and then typing the following in MATLAB command line
>> get_param(gcb,'Capacity')
Additionally, if you are interested in logging the number of entities being served in the block, you can check the option in the Statistics section of the Block Parameters window. This will create an output port for the Entity Server block, which you can connect to a "To Workspace" block to log the values to the workspace. Please refer the attachment for more information.
Thanks
Arvind
