1. A method comprising: receiving an indication of a user selection of an error associated with a product installation; identifying, in a database, metadata associated with the error, including metadata for an action associated with the error; identifying, in the database, metadata for product installations having a matching stream, a matching build number, and a matching error as the product installation; identifying, in the database, other builds in a same stream having the same error; providing, for presentation to the user, information for displaying a graph, the graph including a horizontal line graph including first nodes representing builds in the same stream having the same error; identifying, in the database, other occurrences of the same action and the same error in builds in at least one other streams; providing, for presentation to the user, information for updating the graph with a parallel line for each of the identified at least one other stream, each parallel line including second nodes representing builds in the particular one of the at least one other stream; identifying, in the database, using dates associated with an oldest one of the first nodes and the second nodes, a date associated with the oldest node; and providing, for presentation to the user, information for presenting a list of potential changes, occurring before the date associated with the oldest node and that are candidates for causing the error.
