Filebeat configuration

[mangeshs (Mangesh Shinde)]

I have to read logs from different server so I am using filebeat for that.
in filebeat yml file I have mention

filebeat.inputs:

- type: log
  enabled: true
  paths:
    - /home/3rdisearch-dev/project/mangeshs/logs/indexer-1/logs/*.log

  multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
  multiline.negate: true
  multiline.match: after

output.logstash:
  hosts: ["XX.XX.X.XX:5044"]

and logstash conf file input as

input {
    beats {
	    type => "test"
        port => "5044"
    }
}

sample log file

2021-09-28 11:04:56,060 INFO com.tdg.box.data.indexer.service.SolrIndexerService [Thread-165] Indexed docs:37272
2021-09-28 11:04:58,456 ERROR com.tdg.box.data.indexer.processor.BoxItemProcessor [Thread-166] Exception occured while getting file info, for fileid:473828671090 userId:177129950

	at com.box.sdk.BoxJSONResponse.<init>(BoxJSONResponse.java:32)

my questions are

1. is filebeat is correct
2. what exactly port 5044 is defined. is it logstash running port or anything
3. changes in log file are not reflected in ELK
