conditional entity generation in simevents

Is it possible to generate entity from entity generator with a condition that when the queue attached with the entity generator has entity less than its capacity, a new entity is generated. I tried this thing given in figure below

In my figure, there are 4 entities being generated from entity2 block at the start of simulation and after that whenever an entity exit from queue, a new entity is generated from the other entity generation block.But I am looking for the alternate solution in which i dont have to generate 4 entities at the start of simulation.can anybody guide me if its possible or not.

Hi, I think I might be a bit confused by the question. Did you realize that SimEvents is blocking? When the server is full and the queue is full, the entity generator will be blocked and will stop generating automatically. That might solve your problem, because a new entity is only generated when there is capacity? I'm sure there is something I'm not understanding. Is server capacity or downstream capacity making this difficult? -Teresa

yes I got the solution. The blocking of Entity. Thanks
