Hi All, We are working on Indexing system logs ( nagios log ) to Elasticsearch using logstash. We have two basic doubts on this . 1. We are going to parse nagios log to logstash for every minute, For this every minute , we need to send whole nagios log to logstash , then there is **duplicate issue** for all records expect new lines in log. **How to overcome this issue?** 2. which filter is flexible for this nagios log parsing , please suggest us!! Please Help on this and Thanks in Advance 🙂 ---

> For this every minute , we need to send whole nagios log to logstash Why? It doesn't appear to make any sense. ---
