How to configure Filebeat -> ELK Docker Container correctly?

Elastic Stack Beats
1

Dear All,

I have already installed on my local computer ELK Docker Container and Filebeat.

I could read my local glassfish log directly from Kibana dashboard. But I want that the log file should be forwarding to ELK Container "Logstash" first.

under my ELK Container I found this conf.d folder with the following files

root@4569cf1f66ab:/etc/logstash/conf.d# ls
01-lumberjack-input.conf  02-beats-input.conf  10-syslog.conf  11-nginx.conf  30-output.conf

My current configuration look like here.

filebeat.yml file

################### Filebeat Configuration Example #########################

############################# Filebeat ######################################
filebeat:
  # List of prospectors to fetch data.
  prospectors:
        - /Users/mmlug/Documents/university/project/runtime/glassfish-3.1/glassfish/domains/domain1/logs/server.log
        #- c:\programdata\elasticsearch\logs\*
      input_type: log
      exclude_lines: ["^DBG"]
	  
output:
  ### Elasticsearch as output
  elasticsearch:
	hosts: ["localhost:9200"]

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

Step 1 Starting Docker  : sudo docker-compose up elk
Step 2 : sudo ./filebeat -e -c filebeat.yml -d "publish"

When I enable "Logstash" as a output, I always got an errors as below...

Loading config file error: YAML config parsing failed on filebeat.yml: yaml: line 279: found character that cannot start any token. Exiting.

Many thanks in advance.

Best Regards,
Thomas.

Could it be that your filebeat.yml is much longer then what you posted above? There seems to be a problem on lin 279. Most of the time the issue with yaml is using tabs instead of spaces.

hi ruflin,

Thanks.! Yes, I could fixed the error.
After editing "02-beats-input.conf" under ":/etc/logstash/conf.d" I could now see the glassfish logs in kibana.

Do you know how I can proper display glassfish multiple line logs in Kibana?

Best Regards,
Thomas

That is probably what you are looking for: https://www.elastic.co/guide/en/beats/filebeat/5.0/multiline-examples.html#multiline-examples
