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. Regards, Harsh Bajaj ---
