i read this but no understud

 --eth_hashwatch(=M,M) Defines a min/max watchdog hashrate in MH/s expected when gpus are hashing.  If a GPU falls outside
                              of this range for too long it will be considered faulty and the watchdog will be triggered.  The
                              default min/max values are 2 MH/s and 150 MH/s.  To activate with default values, use
                              --eth_hashwatch.  To set your own values, use e.g. --eth_hashwatch=1.25,60. The same range is used
                              for all gpus in the rig.  A negative value for one side disables it, e.g. use --eth_hashwatch=-1,1000
                              to handle gpu resets that result in huge fake hashrates but no minimum check.

what is  what in this? --eth_hashwatch=1.25,60

i have 6 vega and 1 vega give 45-50mh/s - all rig have 280mh

this option use only1 gpu HR or all rig HR ? what command i must use?
or
this option use for 1,vega- and i use only default command --eth_hashwatch??

i wont restart miner if my rig give 200mh or less. pls what comand i use for this?
or iff my 1 vega go on 0hr
