Sending Nginx logs to elasticsearch using Filebeat

[Raghav_Garg]

Hello,

I am trying to send nginx logs from my app-server to log-server(elasticsearch) using filebeat. I am using Nginx module for this purpose, and it is working great.

But, I am unable to change "index" for these logs. I am trying to configure my filebeat.yml file to achieve this behavior.

filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /home/ubuntu/project/logs/*.log
  fields:
    log_type: pm2-logs

filebeat.config.modules:
  enabled: true
  path: ${path.config}/modules.d/*.yml
  reload.enabled: true
  fields:                # i have added these myself, no docs suggested it.
    log_type: nginx-logs # i have added these myself, no docs suggested it.

setup.template.name: "setup-elk"
setup.template.pattern: "setup-elk-*"

output.elasticsearch:
    index: "setup-elk-%{[fields.log_type]}-%{[beat.version]}-%{+yyyy.MM.dd}"

When I add fields to filebeat.config.modules, it stop sending logs to elasticsearch.

I want my pm2 logs to be saved in the different index than nginx logs. Please let me know, if you guys need more info from my side.!
