Delete data older than 10 days in elasticsearch

问题

I am new to elasticsearch and I want to delete documents in my elasticsearch index which are older than 10 days. I want to keep only last 10 days of data.So is there any way to delete last 11nth day index automatically. What I have tried..

DELETE logstash-*/_query
{
 "query": {
   "range": {
     "@timestamp": {
       "lte": "now-10d"
      }
    }
  }
}

Error I'm getting while running on kibana dev tools

{
"error": "Incorrect HTTP method for uri [/logstash-*/_query?pretty] and method [DELETE], 
allowed: [POST]",
"status": 405
}

Please help to resolve this issues.

You need to leverage the Delete by Query Endpoint, like this:

use POST           use this endpoint
 |                      |
 V                      V
POST logstash-*/_delete_by_query
{
 "query": {
   "range": {
     "@timestamp": {
       "lte": "now-10d"
      }
    }
  }
}
  ^

the query part is fine !!

I am describe diffent approach, then @Val have suggested. You can create 10 indexes (index per day) and each day delete one of the indexes - oldest one.

• Pros: it is very easy to delete or archive old data
• Cons: you need to rewrite your queries if you need to search all days data.
