The following arguments are available:
|
|
|
|
-base-bitmap-id int
|
|
bits being set will all be greater than base-bitmap-id
|

|
-base-profile-id int

profile id num to start from

|
-iterations int
|
|
number of bits to set

-client-type string

Can be 'single' (all agents hitting one host) or 'round_robin'
