1. A method, comprising: detecting, by a network device, a trigger condition at a particular location in a primary directed acyclic graph (DAG) in a computer network, wherein the primary DAG includes a root node of the primary DAG; determining, by the network device, a particular node in the primary DAG at the particular location to act as a remote stitched (RS)-DAG root for an RS-DAG at the particular location, wherein the particular node is a different node in the primary DAG than the root node of the primary DAG; instructing, by the network device, the RS-DAG root to initiate the RS-DAG, the instructing indicating one or more properties for the RS-DAG that are selected to cause additional data regarding the trigger condition to be collected within the RS-DAG and that are different from properties of the primary DAG, wherein a particular child node of the RS-DAG root in the RS-DAG has a different parent node in the primary DAG; and receiving, at the network device, a conclusion message from the RS-DAG root that aggregates the additional data regarding the trigger condition collected within the RS-DAG.
