As a database administrator, you time to time want to monitor or to do any maintenance on a Memcached server. As long as the cache works, we consider the server in a good state and is there nothing that needs to be done.
However, it is always a good practice to review the server used to be able to understand if the cache is suffering from a lack of resources or if the cache is oversized based on the workload.
There aren't any official Memcached tools that pull out stats continuously. There are a few choices between using third-party clients or developing a wrapped script using telnet.
