vFlow Monitoring

vFlow monitoring collects all statistical and diagnostic information about the vFlow itself.

Metric	Type	API Key	Protocol	Description

udp.rate	Gauge	UDPCount	IPFIX	UDP packets per second
decode.rate	Gauge	DecodedCount	IPFIX	Decoded packets per second
udp.mirror.queue	Gauge	UDPMirrorQueue	IPFIX	UDP packets in mirror's queue
mq.queue	Gauge	MessageQueue	IPFIX	Decoded message in mq's queue
mq.error.rate	Gauge	MQErrorCount	IPFIX	Message queue errors per second
udp.queue	Gauge	UDPQueue	SFLOW	UDP packets in queue
udp.rate	Gauge	UDPCount	SFLOW	UDP packets per second
decode.rate	Gauge	DecodedCount	SFLOW	Decoded packets per second
mq.queue	Gauge	MessageQueue	SFLOW	Decoded message in mq's queue
mq.error.rate	Gauge	MQErrorCount	SFLOW	Message queue errors per second
mem.heap.alloc	Gauge	MemHeapAlloc	SYSTEM	HeapAlloc is bytes of allocated heap objects
mem.alloc	Gauge	MemAlloc	SYSTEM	Bytes allocated and not yet freed
mcache.inuse	Gauge	MCacheInuse	SYSTEM	Bytes used by mcache structures
mem.total.alloc	Counter	MemTotalAlloc	SYSTEM	Bytes allocated
