No connections between logstash and filebeats

[dragan979 (Dragan Vucanovic)]

Today is second day i'm spending on ELK stack and have no any experience with this.

My goal:

Create "parent" index (client01) and for all machines related to client01 collect logs so i can filter data based on that "parent" index.

filebeat sends log to logstash, logstash sends it to elasticsearch-serach index from KIBANA

elasticsearch,kibana and filebeat are on the same machine

In elasticsearch created cluster01 index

(no mapping)

i can telnet to ports 9200 and 5044

logstash_simple.conf

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 => "localhost:9200"
        index => "client01-logfiles-%{[beat.version]}-%{+YYYY.MM.dd}"
    }
}

i set basic configuration to get it working and to understand basic concepts

logstash.yml

- type: log

      # Change to true to enable this input configuration.
      enabled: true

      # Paths that should be crawled and fetched. Glob based paths.
      paths:
        - /var/log/audit/audit.log


    	#----------------------------- Logstash output --------------------------------
    #output.logstash:
      # The Logstash hosts
      hosts: ["localhost:5044"]

filebeat -e -c /etc/filebeat/filebeat.yml
