Some embodiments provide a method for determining a realization status of one or more logical entities of a logical network. The method, each time a particular event occurs, increments the value of a realization number and publishes the incremented value to a set of controllers of the logical network. Upon receiving data that specifies the state of a logical entity of the logical network, the method publishes the logical entity state's data to the set of controllers. In some embodiments, the method queries the set of controllers for a realization status of the state data for a set of logical entities that is published to the set of controllers up to a particular point of time. The submitted query, in some embodiments, includes a particular value of the realization number associated with the particular point of time.
