How to Reset ALL Virtual ip:port stats and Overall Stats

What is the command to type in to reset all STATS for Bits In---Out---Conn

 

and for all Virtual ip:port to Reset ALL In -- Out----Conn to reset it back to 0 ?i do not see command to reset unit stats (1st line) but "tmsh reset-stats ltm virtual" and "tmsh reset-stats ltm node" are for virtual and node respectively.

 

 

Whoever knows how to do this, can you type in the commands while it is serving traffic (e.g. - do it on a ACTIVE LTM? ) ?resetting stats should not affect production traffic.
