I would like to map only 5 or so fields in the incoming data, the rest I do not care about  
How would my mapping look like then ?  
Right now it looks like this:

> PUT /\_template/tobias2-all-audit  
> {  
> "order" : 0,  
> "version" : 60001,  
> "index\_patterns" : [  
> "tobias2-all-audit-\*"  
> ],  
> "settings" : {  
> "index" : {  
> "lifecycle" : {  
> "name" : "audit\_policy",  
> "rollover\_alias" : "all-audit"  
> },  
> "number\_of\_shards" : "1",  
> "refresh\_interval" : "5s"  
> }  
> },  
> "mappings" : {  
> "properties" : {  
> "@timestamp" : {  
> "type" : "date"  
> },  
> "measured\_time" : {  
> "type" : "long"  
> },  
> "severity" : {  
> "type" : "long"  
> },  
> "@version" : {  
> "type" : "keyword"  
> },  
> "message" : {  
> "type" : "text"  
> },  
> "service\_name" : {  
> "type" : "text"  
> },  
> "method" : {  
> "type" : "text"  
> }  
> }  
> },  
> "aliases" : { }  
> }
