Issue Filtering and Improved Trace Analysis

Happy 2020! We hope you are as excited for the new year as we are at Memfault.

In this update, we've added improved Issue filtering, automated ISR analysis, a built-in hex viewer into the Trace viewer, and many other improvements.

FreeRTOS Stack High Water Marks and Selective Alerts

FreeRTOS Stack High Water Marks

When using FreeRTOS, Memfault will now show the high water mark of each thread, as well as show when a Stack Overflow has occurred on any thread. This can be applied to any RTOS, so if this is of interest, let us know.

General Improvements

  • Improve FreeRTOS coredump processing
  • Fix an issue where duplicates appeared in Globals and Statics tab
  • Improve response times for the API

Alerts

Trigger alerts based on Heartbeat event metrics, and filter them by metric value and Device properties, such as Cohort, Device Serial, Nickname, Hardware Version, Software Type, and Software Version.

Streamlined API Uploads

Chunk Transport

Released "chunk" transport which provides a streamlined way of getting arbitrary data (coredumps, events, heartbeats, etc.) out of devices and into Memfault.

For more information, check the API documentation.

Easily know which coredumps were recently uploaded, if they experienced any errors, and which Issue they were attached to.

ChibiOS, Complex Devices, and More

ChibiOS Support

Memfault now has support for accepting and parsing coredumps from a device running ChibiOS. It will recover threads, thread state, and global and static variables.
