Heartbeat mechanism

The Heartbeat mechanism is a method used in various systems, like computer networks or distributed applications, to monitor the health and status of components. Think of it like a regular check-in: one system sends a simple signal (the "heartbeat") to another, confirming it is still operational. If the receiving system does not get the signal within a set time, it may assume that the sending system has encountered an issue, allowing it to take corrective action. This ensures reliability and helps maintain smooth operations by detecting and addressing problems early.
