Hey all,  
i have a problem with my grok pattern i have 2 type of logs with have one different and if i create two grok matches with the patterns (all similar until LOGLEVEL pattern) look below:  
my logs

> [9/16/18 19:58:29:827 CEST] 0000006e SystemOut O CIWEB Warn : [ls94mn(unknown) @ 10.16.60.8] de.abc.response.ImportContactsChoiceList.executeFilter() User with bensl=g5082 not found.  
> [9/16/18 20:28:53:225 CEST] 000004cc SystemOut O CIWEB Error: [mfbr8qv(unknown) @ 10.16.60.8] com.ibm.ecm.struts.actions.p8.P8RetrieveItemsAction.executeAction()

my grok matches:

```
grok {
  break_on_match => false
   match => ["message","%{DATESTAMP:time} %{NOTSPACE} %{NOTSPACE:thread} %{WORD:log-source} []* %{NOTSPACE:sev} %{NOTSPACE:module} %{LOGLEVEL:log-level} \: %{GREEDYDATA:msg}" ]
   match => ["message","%{DATESTAMP:time} %{NOTSPACE} %{NOTSPACE:thread} %{WORD:log-source} []* %{NOTSPACE:sev} %{NOTSPACE:module} %{LOGLEVEL:log-level}\: %{GREEDYDATA:msg}" ]
 }

```

If I use this Grok with both matches, the filter only takes the error LogLevel.

please help in that, thank you all
