The debug module uses `Memfault SDK`_ to track |NCS| specific metrics such as LTE and stack metrics.
26-
In addition, the following types of custom Memfault metrics are defined and tracked when compiling in the debug module:
27-
28-
* ``gnss_time_to_fix_ms`` - Time duration between the start of a GNSS search and obtaining a fix.
29-
* ``gnss_satellites_tracked_count`` - Number of satellites tracked during a GNSS search window.
30-
* ``location_timeout_search_time_ms`` - Time duration between the start of a location search and a search timeout.
31-
25+
The debug module uses `Memfault SDK`_ to track |NCS| specific metrics such as LTE, location, Bluetooth and stack metrics.
3226
The debug module also implements `Memfault SDK`_ software watchdog, which is designed to trigger an assert before an actual watchdog timeout.
3327
This enables the application to be able to collect coredump data before a reboot occurs.
