Starting with Junos OS Release 14.2R2 and 15.1R1, you can configure MX Series routers with MS-MPCs and MS-MICs to log network address translation (NAT) events using the Junos Traffic Vision (previously known as Jflow) version 9 or IPFIX (version 10) template format. Flow data is sent to Azure Storage accounts from where you can access it as well as export it to any visualization tool, SIEM, or IDS of your choice. Consequently the number of bytes and packets reported in NSG Flow Logs (and Traffic Analytics) could be different from actual numbers. Flow state B is recorded when a flow is initiated. You will need to choose the log format, facility, host, port and priority then click the save button. Each log record contains the network interface (NIC) the flow applies to, 5-tuple information, the traffic decision & (Version 2 only) throughput information. Templates provide an extensible design to the record format. Any help. The fields that can be matched and exported are preset in the NetFlow v5 protocol, and the template-based v9 offers more flexibility in terms of format. V9 format is template-based.
