Abstract
Computer systems and methods for estimating the number of client computers actively coupled to a server computer system in real-time are discussed herein. Specifically, systems and methods are discussed for a server computer system receiving heartbeat messages from a plurality of client computers and generating an estimate of the number of client computers actively coupled to the server computer system in real-time without locks, such as a database table lock. A heartbeat message from a client computer need not include a client or user identifier. In an embodiment, the memory footprint/overhead is O(l), and may be a single whole number greater than zero, such as a 64-bit unsigned integer. Systems and methods are also discussed herein to calculate and reduce the expected error of the estimated number of active clients.
