Methods and systems are described for receiving data including a hierarchy change log comprising change records specifying changes made to hierarchical data. The hierarchical data includes hierarchically arranged nodes. Change records are grouped according to a key corresponding to each record. Using a record consolidation algorithm, a consolidated view of the hierarchy change log is generated. A consolidated view can be generated by sorting, for each group, the change records into an ascending temporal order based on their respective timestamps to form a sequence of change records. The consolidated view is then displayed on an electronic visual display. Related apparatus, systems, techniques and articles are also described.
