📈 Added

  • Zephyr:

    • Add the following built-in WiFi metrics for Zephyr devices, enabled by
      default on systems with WiFi:

      • wifi_connected_time_ms : time in milliseconds the device has been
        connected to a WiFi network
      • wifi_disconnect_count : number of times the device has disconnected from
        a WiFi network
      • wifi_ap_oui : the OUI of the WiFi AP the device is connected to

      The metrics can be disabled by setting CONFIG_MEMFAULT_METRICS_WIFI=n.

    • The Memfault Zephyr fault handler now labels faults as Stack Overflow, Bus
      Fault, MemManage Fault, and Usage Fault, among others, in addition to the
      existing Hard Fault label. Note that this does not change the types of
      faults collected (all these faults are already supported), but it does
      correct the label presented in the Memfault UI.

    • Add a new test command, mflt test stack_overflow, that will trigger a
      stack overflow fault when CONFIG_STACK_SENTINEL or
      CONFIG_MPU_STACK_GUARD is enabled.

    • The cpu_temp metric has been renamed to thermal_cpu_c to better reflect
      the metric's purpose. The metric is still collected by default on platforms
      with an enabled die-temp0 sensor, and can be disabled by setting
      CONFIG_MEMFAULT_METRICS_CPU_TEMP=n.

    • Add a new metric, memory_pct_max, which captures the max percentage of the
      heap used. It is enabled by default. This metric and the existing
      Heap_BytesFree metric are controlled with
      CONFIG_MEMFAULT_METRICS_MEMORY_USAGE.

  • ESP-IDF:

    • Add an option to upload logs by default when using
      MEMFAULT_HTTP_PERIODIC_UPLOAD, controlled with the Kconfig symbol
      MEMFAULT_HTTP_PERIODIC_UPLOAD_LOGS. This can also be controlled at runtime
      with the included API
      memfault_esp_port_http_periodic_upload_logs(bool enable)

    • Add a new metric, memory_pct_max, which captures the max percentage of the
      heap used. It is enabled by default. This metric and the existing heap_*
      metrics are now controlled with CONFIG_MEMFAULT_METRICS_MEMORY_USAGE.

    • Print the Memfault OTA URL from memfault_esp_port_ota_update() when a new
      update is available, for example:

      esp32> memfault_ota_check
I (98125) mflt: Checking for OTA Update

🛠️ Changed

  • Zephyr:

    • The cpu_temp metric has been renamed to thermal_cpu_c to better reflect
      the metric's purpose. The metric is still collected by default on platforms
      with an enabled die-temp0 sensor, and can be disabled by setting
      CONFIG_MEMFAULT_METRICS_CPU_TEMP=n.

  • ESP-IDF:

    • The cpu_temp metric has been renamed to thermal_cpu_c to better reflect
      the metric's purpose. The metric is still collected by default on ESP32
      variants that support it (all but ESP32), and can be disabled by setting
      CONFIG_MEMFAULT_METRICS_CPU_TEMP=n.

    • The Kconfig CONFIG_MEMFAULT_ESP_HEAP_METRICS has been replaced with
      CONFIG_MEMFAULT_METRICS_MEMORY_USAGE.
