How to delete duplicate logs?

prateedshetty — Wed, 15 Feb 2017 16:08:38 GMT

I've uploaded the same log twice(using drag and drop option in add data) and now when I query I see duplicate results due to this. How do i delete one copy of the log?

There is no log file to delete … your data has been indexed. To get rid of duplicate data from index… you can run a search to identify the duplicate events and pipe it to |delete command.

You can use the delete command. https://docs.splunk.com/Documentation/Splunk/6.5.2/SearchReference/Delete

If you can write a search that limits the data to one copy, then you can pipe it to the delete command so you won't see both.

This will only stop you from seeing it, it will not get rid of the data off the indexer.

You can also clean indexes if one of the copies of data is in a different index than the other you can wipe one of the indexes of all the data in there. http://docs.splunk.com/Documentation/Splunk/6.5.2/Indexer/RemovedatafromSplunk#Remove_data_from_one_or_all_indexes

Like this:

Your Search That Shows Duplicates AND NOTHING ELSE | dedup _raw | delete

You will probably have to extend your user's role/permissions to run the delete command.
