Had an interesting situation come up today with a client. We had a situation where a server crashed because it ran out of memory. The calculation we used to monitor memory usage did not take into account all factors. When looking at this, I noticed a couple of things:\tThere are numerous calculations available online.\tIt seems that none of them take everything in account.Wouldn't it be nice if there was a total possible memory consumption status value? It can be a valuable piece of information. (And while I am requesting things, what about peak memory usage by the mysqld server since it has been online?) Realistically, there is almost no case where you would actually use the maximum amount of memory. But knowing how much memory that MySQL server could possibly use would be a very useful bit of information to know.Second, why isn't there an "official" formula that actually shows everything? It's easy to forget things.  []
