Halo

i want to ask something about my logstash configuration.
i've already installed logstash and giving some configure in

/etc/logstash/logstash-sample.conf

and for the configuration is

input {
beats {
port => 5044
ssl => true
ssl_certificate => "/etc/pki/tls/certs/logstash.crt"
ssl_key => "/etc/pki/tls/private/logstash.key"
}
}

filter {
if [type] == "syslog" {
    grok {
        match => {
            "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}"
        }
        add_field => [ "received_at", "%{@timestamp}" ]
        add_field => [ "received_from", "%{host}" ]
    }
    syslog_pri { }
    date {
        match => [ "syslog_timestamp", "MMM  d HH:mm:ss", "MMM dd HH:mm:ss" ]
    }
}
}

output {
elasticsearch {
    hosts => "100.100.200.151:9200"
    index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
}
}

The logstash work fine. and status logstash is active (running)

but when i check my log in

journalctl --unit logstash

its showing some error. so this is the log

Hi

The log you posted is truncated. Check the line where it says

No config files found in path {:path=>"/etc/

It seems logstash cannot find your .conf file.

In your otuput{} section, comment out the elasticsearch{} plugin and add a stdout{} line. Try again and see what you get.

Hope this helps.
