OpenTSDB filter tags exclude specific tag

Question

Is it possible to query for all possible values but exclude a specific value from search?

For example m=sum:rate:proc.stat.cpu{host=foo,type=*?!user} meaning all values for type but exclude user value. Or something like m=sum:rate:proc.stat.cpu{host=foo,type=*, type=!user}.

Answer 1

Nope, as of OpenTSDB 1.1.0 this isn't currently supported. There is no fundamental reason why it wouldn't be supported, it's just that this isn't implemented yet.

Answer 2

As an update, this is now supported in OpenTSDB versions 2.X using the not_literal_or filter. You can do m=sum:rate:proc.stat.cpu{host=foo,type=not_literal_or(user)}
