anyway to rest isi statistics?

I am trying to find a way to determine how many cee events we send.  I use the command 

isi statistics query current list --keys=node.audit.cee.export.total

                Node  node.audit.cee.export.total

                ----------------------------------

                  12                       531929

                 ----------------------------------

 

But is there a way to reset this counter, then I can check it in a week to see how many events we send in that time?

 

I also see the history option

    isi statistics query history list --keys=node.audit.cee.export.total

 

But that display every 5 seconds for the past hour.
