How do track the request cache -- 3.0.4

Is there any way to have the server to report/log when it has reached the maximum number of requests which the server keeps track of? The default logging doesn't seem to relay that information. Does the status v-server report such things? I understand the server might hit that value, come down, and hit it again multiple times in a very very short period of time, but the information would be nice to have.
