Logstash grok filter does not parse message

Question

In grok Debugger is everything okay but not parse when i start logstash.

Log line:

# Time: 170904 10:16:01\n# User@Host: mmcite[mmcite] @ localhost []\n# Thread_id: 18712  Schema: mmcite  QC_hit: No\n# Query_time: 0.502068  Lock_time: 0.000030  Rows_sent: 0  Rows_examined: 1\n# Rows_affected: 1\nuse mmcite;\nSET timestamp=1504512961;\nUPDATE `ajedem456456` SET `id`='cotjo4mim2j7fp3ui2kit7gns6' WHERE id='pvueh0rm6l2meiguootdfqsan7';

Filter:

grok {

    match => { "message" => "#%{SPACE}Time:%{SPACE}%{NUMBER}%{SPACE}%{TIME}(.|\n)*%{HOSTNAME}\[%{HOSTNAME:mysql_host}\]%{SPACE}@%{SPACE}localhost \[\](.|\n)*#%{SPACE}Thread_id:%{SPACE}%{NUMBER}%{SPACE}Schema:%{SPACE}%{WORD}%{SPACE}%{WORD}:%{SPACE}%{WORD}(.|\n)*#%{SPACE}Query_time:%{SPACE}%{BASE16FLOAT:mysql_query_time}%{SPACE}Lock_time:%{SPACE}%{BASE16FLOAT:mysql_lock_time}%{SPACE}Rows_sent:%{SPACE}%{NUMBER:mysql_rows_sent}%{SPACE}Rows_examined:%{SPACE}%{NUMBER:mysql_rows_examined}(.|\n)*%{SPACE}Rows_affected:%{SPACE}%{NUMBER:mysql_rows_affected}(.|\n)*%{WORD}%{SPACE}%{WORD};(.|\n)*SET%{SPACE}timestamp=%{NUMBER:timestamp};\\n%{GREEDYDATA:mysql_query}" }

}

Output:

Thank your very much for your help.

I have no idea how, but it works.

grok {    
    match => { "message" => "#%{SPACE}Time:%{SPACE}%{NUMBER}%{SPACE}%{TIME}(.|\n)*%{HOSTNAME}\[%{HOSTNAME:mysql_host}\]%{SPACE}@%{SPACE}localhost \[\](.|\n)*#%{SPACE}Thread_id:%{SPACE}%{NUMBER}%{SPACE}Schema:%{SPACE}%{WORD}%{SPACE}%{WORD}:%{SPACE}%{WORD}(.|\n)*#%{SPACE}Query_time:%{SPACE}%{BASE16FLOAT:mysql_query_time}%{SPACE}Lock_time:%{SPACE}%{BASE16FLOAT:mysql_lock_time}%{SPACE}Rows_sent:%{SPACE}%{NUMBER:mysql_rows_sent}%{SPACE}Rows_examined:%{SPACE}%{NUMBER:mysql_rows_examined}(.|\n)*%{SPACE}Rows_affected:%{SPACE}%{NUMBER:mysql_rows_affected}(.|\n)*%{WORD}%{SPACE}%{WORD};(.|\n)*SET%{SPACE}timestamp=%{NUMBER:timestamp};(.|\n)%{GREEDYDATA:mysql_query}" }    
}

I've replaced the \\\\n before %{GREEDYDATA:mysql_query} by (.|\\n) .
