A very important piece of information to take into account is that sometimes, the evaluated period does not include certain events. For example, the login of an agent to their queues, since they might have done so outside of the selected time frame. For this we got the Max Session Allowed (hours) parameter. Its default value is seven (7), this indicates that if the login/logout that completes the event is not found the maximum session time for the agent it would be of 7 hours. This tends to happen when we evaluate short periods lower than 24 hours.
