Techniques are described for tracking data objects transferred among multiple services in a computing environment. Services that are involved in the transfer of data objects may be instrumented to generate recordings that describe outbound and inbound transfers of data objects. The recordings may be analyzed to identify key-value pairs included in the transferred data objects, where the key corresponds to a data attribute that stores a particular value in a data object. For each pair of keys that are associated with a same or substantially similar value, a correlation metric may be updated for each instance of association. Over time, the correlation metric may indicate a higher degree of correlation for those pairs of keys that frequently share a same value. Pairs of keys exhibiting an above-threshold correlation count may be designated as related in that they are involved in the transfer of data objects.
