What is the minimum required fields and requirements, in order for Harvester to process NetFlow.
1. These are the minimum required fields for data to appear in RA/NFA:
One of the following:
1 - IN_BYTES or 85 - IN_PERMANENT_BYTES (NFA only)
*NOTE: For ASA devices we need both 231 - FW_INITIATOR_OCTETS, and 232 - FW_RESPONDER_OCTETS
and the rest:
4 - PROTOCOL
7 - L4_SRC_PORT
8 - IPV4_SRC_ADDR
10 - INPUT_SNMP
11 - L4_DST_PORT
12 - IPV4_DST_ADDR
14 - OUTPUT_SNMP
2. The other question is how much data we are receiving from these interfaces:
The minimum limits for interface data to be included in reports are 50 KB for protocols, and 100 KB for hosts or conversations per 15 mins.
