My ELK Stack is running a process which collects logs from 5-6 different PCs. The only issue I am facing at the moment is, my ES index is logging multiple entries for the same timestamp. Any suggestions on how I can fix and remove the duplicates? The following is an example of how the data is indexed. All 4 entries have the exact same data and I just need one of these. -\> This affects the dashboards and the results that we're trying to observe. ![image](https://us1.discourse-cdn.com/elastic/original/3X/5/9/59a10371c5d32eca3431c19e7ab26139185d211c.png) ---

You can add this in your output, and then you will have 'update' on doc, and no more duplicates. `document_id => "%{[field_with_same_value_for_duplicate_docs]}"` ---
