Hi,

How do i map nginx's body\_bytes\_send field that at times sends '-' and rest of the times a number?

I have tried creating a map type long for this field but it fails when line of logs has "-" in it.  
Can I map this field to two different types, if so how do i do it ?  
what is the recommended solution ?
