Abstract: In one embodiment, a method includes selecting a group of transactions having a common end-to-end transaction path comprising a plurality of transaction-path nodes. Each transaction of the group is associated with either an acceptable category or an unacceptable category based, at least in part, on an end-to-end response time for the transaction. The method further includes separately determining, for each transaction-path node, an execution-time pair. The execution-time pair includes first aggregate information indicative of execution time by the transaction-path node for transactions associated with the acceptable category. The execution-time pair also includes second aggregate information indicative of execution time by the transaction-path node for transactions associated with the unacceptable category. Additionally, the method includes generating a visualization of the end-to-end transaction path.
