Not able to send logs from filebeat to graylog

I am using filebeat -> logstash -> elasticsearch with 6.8.2 version and Graylog 3.1.4. My filebeat collect data from catalina.out log file and send to the logstash then elasticsearch.I am not able to get logs in graylog.What should I do, Please help me

Can you see traffic in IN/OUT box in the top right corner?
That about of System/Input option?

You can’t directly send data to Elastic, you need to send it to graylog Input type beat, so logstash output setup for logstash and point to graylog input.

No am not able to see traffic in IN/OUT



  • type: log
    enabled: true
    • /usr/share/filebeat/mylog/apache-tomcat-9.0.36/logs/catalina.out
      loadbalance: true

hosts: [“logstash:5044”]


input {
beats {
port => 5044

filter {
json {
source => “message”
match => [“timestamp”, “UNIX_MS”]
target => “@timestamp
ruby {
code => “event.set(‘indexDay’, event.get(’[@timestamp]’).time.localtime(’+09:00’).strftime(’%Y%m%d’))”

user => elastic

password => elastic


output {
elasticsearch {
hosts => [“elasticsearch:9200”]
template => “/usr/share/logstash/templates/logstash.template.json”
template_name => “logstash”
template_overwrite => true
index => “logstash-%{indexDay}”
codec => json
stdout {
codec => rubydebug

I want to send logs from filebeat to graylog directly or using logstash

How do you are deploying graylog? with docker?. In case of negative response you need configure the correct host or IP here.

hosts: [“logstash:5044”]

Also you can check if your services are running, and if you can reach to these services using telnet, ping, nslookup.

ping logstash
telnet elasticsearch 9200

And is really important check filebeat logs. Usually located in /var/log/filebeat
