here is my logstash.conf

input{
    file{
        path => "D:/server.log" start_position=> "beginning" type => "logs"
    }
    }
filter{
    grok{
        match => {'message'=>'\[%{TIMESTAMP_ISO8601:logtime}\]%{SPACE}%{LOGLEVEL:loglevel}%{SPACE}\[(?<threadname>[^\]]+)\]%{SPACE}%{WORD}\:%{WORD}\:%{WORD}%{SPACE}\(%{WORD:className}\.%{WORD}\:%{WORD}\)%{SPACE}\-%{SPACE}%{GREEDYDATA:errorDescription}'

        }
        add_field => {
            'eventName' => 'grok'
        }   
        }
    }
output{
        elasticsearch{
            hosts=>["localhost:9200"] 
            index=>"tuesday"
        }
}

did i miss any configuration ? or what am i doing wrong here.

Hej:

Without knowing more WORD seems to be defined as \b\w+\b which means that it is expecting a blank space before and after the characters which in your case it might not apply, Maybe use \w+ instead of %{WORD}. Or use another alias that does not expect a blank space before and after.
