filtering netflow fields

[Alisher-Nabiev]

Hi, I am using NetFlow to receive data from a port. I am trying to filter the data and output certain fields to Elasticsearch.

This is the information that I am trying to read off :
"last_switched",
"first_switched",
"in_pkts",
"input_snmp",
"output_snmp",
"src_tos",
"ipv4_next_hop",
"dst_mask",
"src_mask",
"tcp_flags",
"in_dst_mac",
"out_src_mac",
"postNATSourceIPv4Address",
"postNATDestinationIPv4Address",
"postNAPTSourceTransportPort",
"postNAPTDestinationTransportPort",
"fsId",

but didn't find any way to filter the incoming data.
can someone pls guide me on how can i achieve this?

Hello @Alisher-Nabiev
You should be able to use the omit filter for this task
