以下是事件消息的示例：
{
"timestamp":"2016-03-29T22:35:44.770750-0400",
"flow_id":45385792,
"in_iface":"eth1",
"event_type":"alert",
"src_ip":"3.3.3.8",
"src_port":21,
"dest_ip":"2.2.2.2",
"dest_port":52934,
"proto":"TCP",
"alert":{
"action":"allowed",
"gid":1,
"signature_id":4027,
"rev":0,
"signature":"FTP Successful Login",
"category":"",
"severity":3
},
"payload":"MjU3ICIvaG9tZS9uZXd1c2VyIg0K",
"payload_printable":"257 newuser",
"stream":0,
"packet":"AFBWo0NoAFBWoxZWCABFAABJKDpAAEAGCGcDAwMIAgICAgAVzsbd4MhqOBOjfoAYAOMYcwAAAQEIChHN4EQHnwugMjU3ICIvaG9tZS9uZXd1c2VyIg0K"
}
input
beats
port => 5044
codec => json
type => "SuricataIDPS"
我的 Logstash 配置文件如下：
output
elasticsearch
hosts => ["localhost:9200"]
sniffing => true
manage_template => false
index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
#document_type => "%{[@metadata][type]}"
我希望能够重命名该字段alert.signature，
我该怎么做？...似乎它不识别该字段...
感谢您的帮助！
