Memfault is a device observability platform that complements traditional debugging tools by providing remote diagnostics and fleet-wide insights. It is particularly valuable in the following situations:
- The devices are deployed in remote or inaccessible locations, and you need to capture crashes and diagnostics without physical access or a live debug session.
- The issues only reproduce under real network conditions, or they occur sporadically and are difficult to recreate on the bench.
- You need the full post-mortem context to find the root cause of crashes after the fact, such as the register state, the stack traces, the memory contents, and optionally the modem traces.
- You want to track the device health, the LTE connectivity, the stack usage, and the memory statistics across an entire fleet, and watch the trends over time.
- You want to spot systemic issues that affect specific firmware versions, hardware batches, or network configurations, and collect crash data to identify recurring patterns.
