Logstash解析字段问题

Question

我有一个日志打印如下，

"message" => "....",
"host" => "10.10.12.13",
"@version" => "1",
"@timestamp" => "2016-04-13T01:52:43.535Z",
 "DISMAN-EVENT-MIB::sysUpTimeInstance" => "22 days, 16:33:23.24",
"SNMP-MIB::OID_0" => "example::bgpPeerState",
"source_ip" => "10.10.12.13"

我想解析基于前缀 "specific" 的字符串并为此添加一个字段并删除原来的

"SNMP-MIB::OID_0" => "example::bgpPeerState"

它应该如下所示，

   "message" => "....",
 "host" => "10.10.12.13",
 "@version" => "1",
 "@timestamp" => "2016-04-13T01:52:43.535Z",
 "type" => "snmptrap",
 "DISMAN-EVENT-MIB::sysUpTimeInstance" => "22 days, 16:33:23.24",
 "example" => "bgpPeerState",
"source_ip" => "10.10.12.13"

我的会议，

filter
 {
        if "example" in [SNMP-MIB::OID_0] {
               # I don't how to parse it and add a field  ???

              }
      else
      {
                 .......
       }

}

一如既往，非常感谢您的帮助！

使用kv过滤器：

filter {
    if "example" in [SNMP-MIB::OID_0] {
        kv {
            source => "SNMP-MIB::OID_0"
            value_split => ":"
            trim => ":"
            remove_field => "SNMP-MIB::OID_0"
        }
    }
}

}
