Help using logstash dissect filtering

[retroisbest]

Hi there,
I'm trying to map my fields using dissect, my data has no common delimiter apart from spaces.

My filter section in logstash config looks like this

 if [type] == "syslog"
{
    dissect {
      mapping => {
      "message" => "%{IP_Address->} %{LMonth} %{LDay} %{LTime} %{Host_Name} %{Facility} %{Priority} %{Tag} %{Message}"
               }
       } 
 }

Yet my mapped fields contain data that should of been split

192.168.2.1 May 20 15:29:44 kern warning kernel DROP_INPUT IN=red0 OUT= MAC=d4:ae:52:a0:84:fb:00:57:d2:79:93:c2:08:00 SRC=xx.xx.xx.xx DST=xx.xx.xx.xx LEN=443 TOS=0x00 PREC=0x00 TTL=48 ID=34493 DF PROTO=UDP SPT=5077 DPT=1023 LEN=423

So my IP_Address field contains "192.168.2.1 May" This is the same then for the fields that follow.

Any help you be greatly appreciated!
Thankyou

Is the separator between the IP address and the month actually a tab rather than a space?

[retroisbest]

Yes it is...it seems to be a space and a tab after some fields, can i use a literal tab or is there a character to be used?

For future reference its a literal tab, thanks for pointing me in the right way @Badger
