Hi Daniel, Thank you for looking at the patch again. When I do not use cpu as a field, I am not able to make it part of the key or value fields. I can only use cpu in the filter predicate. For example, the following trigger does not seem to work: 'hist:key=ltype,cpu:val=latency:sort=ltype,cpu if ltype==0' But the following works: 'hist:key=ltype,latency:val=hitcount:sort=latency if cpu==1' -Binoy
