Hey Hau,
In regards to the counts. You have ***/*** (***/***). The first set of numbers is the total number of Agents/CPU's used against the license. The number in the parenthesis is the total number of agent and cpu for that license category for that environment.
An example of these two being different is when you have multiple Agents on one server. For example if I had two Windows agents running on HOST1, I would see 00001/00002 (000002/000004). It will only count as one license entry against the license because they are both running on the same IP address.
