Symbiotic stars are strongly interacting systems with orbital periods of hundreds to thousands of days. The long-term photometric, as well as spectroscopic observations of these systems, are needed to study the physical mechanism responsible for their observed activity.

Both amateur and professional astronomers play important role in such monitoring. We present the preliminary results of the investigation of symbiotic systems AG Dra, Z And and AG Peg during their current active stages based on spectroscopic and photometric measurements obtained by amateur astronomers grouped in the Astronomical Ring for Amateur Spectroscopy (ARAS) and American Association of Variable Star Observers (AAVSO), respectively.
