Filebeat Is not Sending Logs to Logstash even Harvesting Successfull

mgnfcnt · January 26, 2020, 7:46pm

I am trying to use ELK space to collect file logs. Everything is OK untill filebeat integration. I can send the logs over tcp to logstash and see in the kibana.
But I couldn't achieved filebeat setup to send the logs. It seams sending the data but can not see at elasticsearch.

Using this command to create elasticsearch.

docker run -d -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" --name elasticsearch docker.elastic.co/elasticsearch/elasticsearch:7.5.2

Kibana:

docker run -d -p 5601:5601 -h kibana --name kibana --link elasticsearch:elasticsearch docker.elastic.co/kibana/kibana:7.5.2

Logstash:

docker run -d -p 5044:5044 -p 5000:5000 -h logstash --name logstash --link elasticsearch:elasticsearch -v c:/elk2/config-dir:/config-dir docker.elastic.co/logstash/logstash:7.5.2 -f /config-dir/logstash.conf

Logstash.conf file

input {
    beats {
	    type => "test"
        port => "5044"
    }
}
 
filter {
  #If log line contains tab character followed by 'at' then we will tag that entry as stacktrace
  if [message] =~ "\tat" {
    grok {
      match => ["message", "^(\tat)"]
      add_tag => ["stacktrace"]
    }
  }
 
}
 
output {
   
  stdout {
    codec => rubydebug
  }
 
  # Sending properly parsed log events to elasticsearch
  elasticsearch {
    hosts => ["elasticsearch:9200"]
  }
}

Running filebeat on windows 10 machine. Downloaded zip and filebeat.yml config

filebeat.modules:
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - C:/elk2/filebeat/log/*.log
  multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
  multiline.negate: true
  multiline.match: after
  
output:
  logstash:
    hosts: ["localhost:5044"]
#Also tried 127.0.0.1/logstash/ip... as hosts here

Running powershell as admin mode and first

./install-service-filebeat.ps1

then

./filebeat.exe -c ./filebeat.yml

But no result at elastic search.

Hey!

As you mentioned, maybe Filebeat cannot parse the logs. In order to verify that you should just focus on Filebeat's part:

For debugging this use console.output instead of sending to Logstash -> https://www.elastic.co/guide/en/beats/filebeat/current/console-output.html
I would suggest to first try with a bare minimum config like https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-input-log.html#filebeat-input-log (without multiline settings) and later try to add them.

Could you check if there are any errors reported in Filebeat's output while running with the above steps? (also you can provide the output here)

Thank you!

Hey @ChrsMark It is not consistent for now, when first start it is sending sometimes, but not mostly here are my latest settings:

filebeat.yml

filebeat:
  prospectors:
    -
      paths:
        - C:/elk2/logs/*.log
      input_type: log
      multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
      multiline.negate: true
      multiline.match: after
      
output:
  logstash:
    enabled: true
    hosts: ["localhost:5044"]

logging.level: DEBUG
logging.selectors: ["*"]

logstash.conf

input {
    beats {
        port => 5044
    }
}
 
output {
  elasticsearch {
    hosts => ["elasticsearch:9200"]
  }
}

logstash docker command:

docker run -d -p "5044:5044/tcp" -p 5000:5000 -p 5144:5144 -p 5244:5244 -h logstash --name logstash --link elasticsearch:elasticsearch -v c:/elk2/config-dir:/config-dir docker.elastic.co/logstash/logstash:6.5.1 -f /config-dir/logstash.conf
