  • Monitoring a Low-Power Wireless Network Based on Smart Mesh IP

    by Fabian Graf

    This blog post provides a practical tutorial demonstrating a simple APM solution for low-power devices. The solution leverages Zephyr RTOS on an nRF52, and SmartMesh IP on an Analog LTC5800 which can accommodate an arbitrary number of wireless motes. The motes can send a set of performance metrics at certain heartbeat intervals via a framework provided by Memfault. The framework is scalable and allows the creation of a customized group of metrics.

  • Best Practices for Monitoring Device Connectivity

    by Eric Johnson

    This post will cover why device connectivity is complex and what methods we have available to diagnose and solve connectivity problems, both in the office and remotely in production. The tool at the core of our strategy is metrics, but we’ll briefly survey other tools like logging and protocol analysis. We’ll look in-depth at the utility of metrics and wrap up with some practical metric examples to use in your device.

  • Counting Crashes to Improve Device Reliability

    by Tyler Hoffman

    This post will cover the most common reliability metrics that hardware manufacturers use. It will explore which are best for IoT devices, including a novel measurement, Crash Free Hours. We’ll cover exactly what you’ll need to collect on your devices within firmware to measure device reliability and ensure your devices are working as expected.

  • Understanding Battery Performance of IoT Devices

    by Tyler Hoffman

    In this post, I’ll cover how to start thinking about collecting metrics that contribute to battery life, how to dig into this data for individual devices, and finally how to aggregate all metrics from devices in the field to accurately predict the battery life of devices in the field for a given firmware release. All of these abilities will help projects optimize battery life and combat issues quickly when they arise, whether you have ten or a million devices in the field.

  • Monitoring Fleet Health with Heartbeat Metrics

    by Tyler Hoffman

    In this post, we lay the foundation for how an organization should instrument their embedded firmware to measure performance, stability, and the overall “health” of each device and an entire fleet of devices. We also compare and contrast the various approaches projects generally take to surface these metrics and I’ll discuss why I believe heartbeat metrics are the best method for driving product decisions.
