Re: IP pool monitoring
Where is the problem in the first place? If a /24 is insufficient, use a /22. And, shorten the lease time to, say, 10 minutes. Otherwise, disconnected clients will not give up their addresses quick enough with high demand.
As for your question, I wonder if there is an event logged in FAZ. Maybe not for "pool depleted" but for the subsequent address assignment failures. If there is such a message you could trigger an action on this event.
