Essential Device and Firmware Metrics
Tyler Hoffman

As embedded engineers, we love data. Our desk is littered with tools that help capture tons of data, such as oscilloscopes, logic analyzers, debuggers, tracers, and power meters. However, once a device (or thousands) leave our desk and are shipped to customers, all of these tools are paperweights. It's now up to the devices to report issues back to the developers.

This is where metrics come in. Throughout my career, metrics have been the most powerful and simplest way to monitor thousands to millions of devices. This talk covers what metrics are, how to capture them, and explores the seemingly infinite metrics you can capture and creative uses to help you solve real-world, elusive device issues, such as power consumption, performance, and battery life issues.
