Hello, I am using the ELK stack to parse and index log files and am currently trying to configure the way the data is indexed.

I currently have a piece of code that looks like this:  
(the spacing has been reformatted to fit the message)

curl -XPUT 'URL' -d '{  
"trigger" : { "schedule" : { "interval" : "10s" } },  
"input" : {  
"search" : {  
"request" : {  
"indices" : ["edge2016"],  
"body" : {  
"query" : {  
"bool" : {  
"must" : [  
{ "match" : {"message": "ORA600" } },  
]  
}  
}  
}  
}  
}  
},  
"condition" : {  
"compare" : { "ctx.payload.hits.total" : { "gt" : 0 }}  
},  
"actions" : {  
"index\_payload" : {  
"index" : {  
"index" : “HARD CODED CUSTOMER NAME",  
"doc\_type" : "my-type"  
}  
}  
}  
}’

I would like to be able to use a variable from the data to set the index.  
So it would look something like this:  
"index" : {  
"index" : "variable from data field $CustomerName",  
}

Is this at all possible?

Many Thanks,

Matt
