According to the doc of logstash  
" ```  
filter {  
grok {  
match =\> ["message", "PATTERN1", "PATTERN2"]  
}  
}

```auto

I wrote my filter as : 
filter {
  grok {
    match => {
      "message" => [
        "%{TIMESTAMP_ISO8601:timestamp} \| %{LOGLEVEL:log_level} \| \[%{DATA:thread}\] --- %{NUMBER:process_id} \| %{DATA:class} \| \| %{GREEDYDATA:message}(\\r|\\n)?",
        "%{TIMESTAMP_ISO8601:timestamp} \| %{LOGLEVEL:log_level} \| \[%{DATA:thread}\] --- %{NUMBER:process_id} \| %{DATA:class} \| \| Started %{DATA:SEND_AGENT_REF_TO_S3} \(direct:\/\/agentRefFromSiCas2-3\)"
      ]
    }
  }
}

Logstash seems to start fine with both configurations and report no errors, but the grok parsing isn't working properly with multiple grok patterns yet.

Welcome to the community. Multipattern is working fine.  
grok {  
break\_on\_match =\> true  
match =\> { "message" =\> ["patter1", "pattern2"] }  
}  
Which an issue do you have?  
Have you tested both grok, independently?  
Can you show us a sample of data?
