Linux file beat configuration not working

i'm trying to take log from linux machine with oracle database installed. Based on the below configuration the filebeat doesn't pull any info to elastic search.

filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /u01/app/oracle/diag/rdbms/trace/alert_oracle*.log
  fields:
   log-type: "oracledb"
   log-subtype: "alertlog"
   customer: "default"
   n4-type: "dbalert"
  multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
  multiline.negate: true
  multiline.match: after
  ignore_older: 168h
  close_inactive: 24h

output.logstash:
  hosts: ["logstash host server":5044"]
  loadbalance: true

can anyone advice how the filebeat yml file need to be configured for linux?

Hi @Kannan_Rajendran !

It seems that we are setting Filbeat to send logs to Logstash:

Is this what you want?
