Hi guys,

I am trying to pars a log file of ~500 lines to find the following two lines: flaked=yes && platform=aws so that I can add these lines as attributes for the given event/document.  
The configuration (logstash.conf):

```
filter {
  grok {
    patterns_dir => ["/usr/local/src/logstash/pattern"]
    match => { "message" => "%{FLAKED:flaked} %{PLATFORM:platform}" }
    }
  }

```

My pattern file:  
FLAKED flaked\s\*=\s\*._?$  
PLATFORM platform\s_=\s\*.\*?$

The configuration above results in the following error:  
"tags" : [  
"multiline",  
"\_grokparsefailure"  
]

The expressions are correct, it is working perfectly fine if I just use/call one of them. Do you guys know what the problem is and how to solve it?

Thanks!

Use a `stdout { codec => rubydebug }` output to show us exactly what the event you want to match look like.
