Flow Data Fields Consumed by NetProfiler The following table shows the flow fields that are consumed by NetProfiler. When you configure third-party devices to export flow, you must include as many of the following fields as supported by the third-party device. Field Name Description Flow Versions with Support Connection initiator Indicates which host initiated the conversation. Used for proper client/server determination. NetFlow v9 Source IP address Source IP address of conversation. All standard versions Destination IP address Destination IP address of conversation. All standard versions Inbound SNMP ifindex SNMP ifindex that identifies the interface through which the conversation is received for the device. All standard versions Outbound SNMP ifindex SNMP ifindex that identifies the interface through which the conversation is transmitted out of the device. All standard versions Packet count Number of packets sent during the conversation. All standard versions Byte count Number of bytes sent during the conversation. All standard versions Timestamps Time stamps for the beginning and end of the conversation. All standard versions Source port Source port being used. All standard versions Destination port Destination port being used. All standard versions TCP flags Set TCP flags . NetFlow v5 and v9 on most devices, sFlow v5 Layer-4 protocol Layer-4 protocol identifier. All standard versions QoS information Type of service (TOS), differentiated services code point (DSCP). All standard versions Time-to-live (TTL) Time-to-live value observed when the packet traversed the reporting device. NetFlow v9 Application identifier Layer-7 application identifier. NBAR through NetFlow v9 with specific hardware (also available from Packeteer through FDR records), Citrix AppFlow, NBAR v2,SteelHead (v8.5 and later), NetShark v10.5, Palo Alto Retransmitted bytes and retransmitted packets TCP transmission counters. SteelFlow Net from SteelHeads, and NetSharks Network round-trip time Measurement of round-trip time across the network. SteelFlow Net from SteelHeads and NetSharks Total response time, server delay, client delay Measurement of response time metrics across the network. SteelFlow Net from NetSharks VoIP metrics: MOS R-Factor score Jitter RTP packet loss Voice-over-IP-metrics computed by the NetShark. NetShark v9.5 and later export Loss A count of the number of lost packets from the sequencing information. MediaNet Jitter Mean jitter for the RTP stream. MediaNet ICMP Type ICMP type. ASA NSEL ICMP Code ICMP code. ASA NSEL Event High-level event code. ASA NSEL Event Time Time since the UNIX epoch when the event occurred. ASA NSEL Forward Flow Delta Bytes Source to destination specific traffic counts. ASA NSEL Reverse Flow Delta Bytes Destination to source specific traffic counts. ASA NSEL
