Hello, I have a following problem, hope somebody can help.  
I have a total count (TC) of agents (hard limit = number of seats) and I need to display their statuses over time: AVAILABLE, BUSY, ON\_BREAK and ABSENT. FIrst three statuses should be result of the term aggregation, but the ABSENT one should be TC - (size(AVAILABLE) +size (BUSY) + size (ON\_BREAK)).

Would it be possible to cap the size of the ABSENT bucket to TC - (sum of other bucket sizes).  
My client is grafana so I guess It has to be on the ES side, if it is possible at all.

Thanks,  
Milan
