I have been 'punishing' on purpose 'cephfs1.metadata' on some clients creating and deleting files/dirs.

My question are for the columns below ,  the values showed are 'accumulatve' stats figures,  right?  
I mean, from what i did, that makes sense.  
It cannot be values per second, right?
Is there a way to reset such columns values?

RD_OPS     Total number of read operations requested for this pool. 
RD    Total number of bytes read from this pool. 
WR_OPS     Total number of write operations requested for this pool. 
WR     Total number of bytes written to the pool. Note that , writing the same object many times will result is that the pool's usage will remain the same but the number of bytes written to the pool will grow. 

Thanks in advance for any comment
