Error when starting up Logstash

[sud0 (Luke)]

When starting Logstash, I get the following error:

My logstash.conf file:

    if [type] == "apache_b2b_access_log" {

        mutate {
            replace => { 'host' => 'webserver.datacentre.example.com' }
            add_field => { 'environment' => 'production'
                           'service' => 'apache_proxy'
            }
        }

        grok {
            match => {
                "message" => "(?<timestamp>%{YEAR}-%{MONTHNUM}-%{MONTHDAY}%{SPACE}%{TIME}),%{SPACE}%{IPORHOST:clientip},%{SPACE}%{NUMBER:port},%{SPACE}%{NUMBER:start_time},%{SPACE}%{NUMBER:end_time},%{SPACE}(?:%{NUMBER:bytes_delivered}|.*),%{SPACE}(?:%{WORD:reference}|.*),%{SPACE}%{WORD:method},%{SPACE}%{NUMBER:status_code},%{SPACE}%{URIPATHPARAM:request_uri},%{SPACE}%{GREEDYDATA:general_data}"
            }strong text
        }

        date {
            match => ["timestamp", "YYYY-MM-dd HH:mm:ss"]
            target => "@timestamp"
        }
    }

# Elastic setup

output {
    elasticsearch {
        hosts => ["localhost:9200"]
        # Weekly index (for pruning)
        index => "mw-log-index-%{+YYYY.'w'ww}"
    }
    stdout { codec => rubydebug }
}

I have got that logstash.conf file for ages... and maybe with the new version of logstash some parameters have changed?

Thanks!

That's not a valid logstash.conf (it never starts the filter section) and does not contain the text that logstash complains about, so clearly either the quote is incomplete or you have another file as part of your configuration.

You're right... my logstash.conf file was not correct. After getting it fixed, logstash is working fine. Thanks!
