Network monitoring

A manager device comprising:

• a processing unit comprising least one processor;
• at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the processing unit, cause the manager device to perform:
• establish a data connection to the plurality of agent devices, the data connection carrying a request to transmit measurement data from the plurality of agent devices, the request comprising an indication defining at least one instant of time for initiating a measurement for generating the measurement data,
• receive the measurement data from the plurality of agent devices, the measurement data is transmitted by the plurality of agent devices in response to the generation of the measurement data in accordance with the indication comprising the at least one instant of time for initiating the measurement by applying a common clock signal for the generation of the measurement data by the agent devices.
