A system for supporting a distributed application includes a plurality of servers, where each of the plurality of servers includes a thread that processes a request received by the distributed application and a monitoring agent that constructs a transaction path for the request and annotates the transaction path in accordance with a writing action to a log of the distributed application to produce an annotated transaction path. In another embodiment, a system for monitoring a distributed application for errors includes a processor and a computer readable storage medium that stores instructions which, when executed, cause the processor to perform operations including constructing a transaction path for each request received by the distributed application, detecting a writing action to a log of the distributed application, and annotating the transaction path in accordance with the writing action to produce an annotated transaction path.
