What is usedHeap?
This gauge reports the amount of heap memory, in bytes, currently allocated and in use by the IN3000's firmware. An admin polls this value over time to watch for memory leaks, where usedHeap climbs steadily and never falls back down even during idle periods. Seeing usedHeap approach initHeapSize would warn an admin that the device is nearing exhaustion of available memory and may soon start failing allocations.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.426.1.8.2 snmpwalk -v2c -c public <target> COMPEX-IN3000::usedHeap
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.426.1.8.2.1 snmpget -v2c -c public <target> COMPEX-IN3000::usedHeap.1
