What is freeHeap?
This gauge reports the amount of heap memory, in bytes, currently available for the IN3000's firmware to allocate. An admin watches this as the inverse of usedHeap, treating a value trending toward zero as an early warning of an impending noMemoryAvailable condition. If freeHeap drops sharply after a configuration change, an admin would suspect that change triggered a memory leak worth investigating.
