Hi....

I logging nginx log with json, include request\_body.

My structure is [server - logstash - logstash - elasticsearch - kibana].

Request\_body's content is also json with escape characters, and sometimes just plain text.

That's is problem..!!

I successfully configure logstash config, but sometimes error occurred, when request\_body is text.

How to I configure elasticsearch index template - mapping?

I want to receive 1)+2) both type.

1. 

"request\_body": {  
"type": "text",  
"fields": {  
"keyword": {  
"type": "keyword",  
"ignore\_above": 256  
}  
}  
}

1. 

"request\_body": {  
"properties": {  
"enveloped\_message": {  
"properties": {  
"channel": {  
"type": "text",  
"fields": {  
"keyword": {  
"type": "keyword",  
"ignore\_above": 256  
}  
}  
},  
"app\_version": {  
"type": "text",  
"fields": {  
"keyword": {  
"type": "keyword",

A single field in an index can only be mapped one way, so the `request_body` field can not be mapped as both `text` and `object` in the same index. Either you need to change the structure so they are aligned, e.g. by moving the text content into a field under `request_body`, or store them in different indices.
