Use log IAM only 1 user

Hi,

In the use log in IAM I can see the use_log_sessions by many users.

Only 1 user does have use-log_actions?

How can I turn on the logging for other users?

And can I query the number of times a task is used by a user?

I can see some data but this is more than 1 month ago. 
 

select * from use_log_usr_action where project_id = 'serp'

and usr_action_type_id like '%task%'

and project_vrs_id in ('1.54','1.55','1.56','1.57','1.58')

order by date_time desc
