Hi all,  
i have a little problem with this type of log:

Wed Sep 20 16:02:39 2017 (186085) -7- ================= FUNCTOR WAITING FOR MSG =================  
Wed Sep 20 16:02:39 2017 (284410) -7- \<----------RECVFROM \<- len [193] bytes  
Wed Sep 20 16:02:39 2017 (340305) -7- Received():13624,0,20001,QLen is 0  
Wed Sep 20 16:02:39 2017 (340329) -7- IPCMutexResource::lock  
Wed Sep 20 16:02:39 2017 (340337) -7- FUNCTOR-ROW: Received pid=13624 id=0 loop=0 port=20001 queuelen=0 recv=258976 sent=258953 status=3

I'm using the followinf configuration in logstash:

filter {  
grok {  
match =\> ["message", "\A%{HTTPDERROR\_DATE:timestamp} (%{NUMBER:bytes}) %{GREEDYDATA:message} "]  
}  
date {  
match =\> ["timestamp", "EEE MMM dd HH:mm:ss yyyy"]  
timezone =\> "Europe/Rome"  
target =\> "@timestamp"  
}  
mutate {  
remove\_field =\> ["timestamp"]  
}

I would like to have every line separate from the other, so the separator is the date, but if the timestamp is equal, i will have all messages in a single block.

Can you help me please?

It won't do that, it will treat each line as a separate event.

However your pattern isn't valid, it should be;

```auto
%{HTTPDERROR_DATE:timestamp} \(%{NUMBER:bytes}\) %{GREEDYDATA:message}

```

Hi all,  
problem was solved.  
I have for other logs the following properties enabled:  
multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'  
multiline.negate: true  
multiline.match: after

Disabled the rules, now logs has been processed in the right manner.  
Thank's to everyone.
