I have 18 headers when I set columns, but the index for kibana only shows 13 why?
My settings:
filter {
csv {
separator => ","
#autogenerate_column_names=> true
columns=> [
"device_dev_name",
"device_family_name",
"device_hashed_mac",
"device_os_name",
"device_type_name",
"device_vendor_name",
"event_protocol_id",
"event_flow_outbound_or_inbound",
"event_role_device_or_router",
"event_role_server_or_client",
"event_rule_category",
"event_rule_id",
"event_rule_name",
"event_rule_reference",
"event_rule_severity",
"event_self_ipv4",
"event_time",
"router_ip"
]
#skip_header=> false
#autodetect_column_names=> true
#skip_empty_columns=> true
#skip_empty_rows=> true
#periodic_flush => true
id => "csv"
convert => {
"event_protocol_id" => "integer"
}
}
