Quota monitors total size of data transferred over any selected filter in any given direction (in, out or both). The user specifies size of the quota and when the quota is exceeded, NetLimiter can take an action like showing notification window or starting predefined rule. For example, user can instruct NetLimiter to start traffic rate limit to restrict further amount of data transferred when an application exceeds it's quota.
Internally, quota is rule so you can create and manage quota the same way as any other rule like Limit or Blocker. It also means that you can start, stop or reset the quota measurement at specific time using Rule Scheduler. For example, the rule scheduler can reset the quota at the beginning of each month.
In next chapters we will show few examples to demonstrate how quotas could be used.
