HI @divyadaka,

Could you pls share the elasticsearch and logstash logs for more understanding.

ES Log: /var/log/elasticsearch/.log
Ls Log: /var/log/logstah/.log

Also, share the YML file for both.

ES conf file: /etc/elasticsearch/elasticsearch.yml
Ls pipeline file: /etc/logsatsh/.yml

Regards,
Harsh Bajaj

Hi @divyadaka,

FOr elasticserch and logstash logs you can check the date and time and share accordingly when the problem is arise.

For Yml file i mentioned above i.e. elasticsearch.yml file and in logstash pipeline file where you mentioned input plugins.filter plugins and o/p plugins.

I can understand about security concern and please don't share information related to you organization/business.

In your logstash configuration you have add TLS related setting to a file input. The file input does not support TLS, so you need to remove them.
