Your smart factory is equipped with 5,000 sensors monitoring everything from temperature and humidity to machine vibrations and production quality. Your IoT dashboard shows green across the board - all devices are connected, data is flowing, and alerts are quiet. Then you discover that Production Line 7 has been producing defective parts for the past six hours because a critical temperature sensor has been sending stale data, but your monitoring system couldn't detect the difference between fresh readings and cached values.
This scenario illustrates the fundamental challenge of IoT monitoring. Traditional IT monitoring focuses on servers and applications that are designed to be observable and manageable. IoT devices often operate in harsh environments, have limited communication capabilities, run on battery power, and can fail in ways that aren't immediately obvious from basic connectivity checks.
IoT monitoring requires understanding the physical world constraints that affect connected devices. Network connectivity might be intermittent. Power sources might be unreliable. Environmental conditions might affect sensor accuracy. Device lifecycles might span years rather than the months typical for IT equipment, requiring monitoring strategies that account for gradual degradation and aging.
