Abstract
A technique involves managing state changes of a data storage system in a computerized device configured to obtain object trees representing state information of the data storage system. The technique includes receiving a first object tree which represents the data storage system at a first time, and receiving a second object tree which represents the data storage system at a second time. The second time is after the first time. The technique further includes generating a set of tree comparison results from a comparison between the first object tree representing the data storage system at the first time and the second object tree representing the data storage system at the second time. The set of tree comparison results indicate whether state changes have occurred in the data storage system.
