In one embodiment, a server determines a trigger to diagnose a software as a service (SaaS) pipeline for a SaaS client, and sends a notification to a plurality of SaaS nodes in the pipeline that the client is in a diagnostic mode, the notification causing the plurality of SaaS nodes to establish taps to collect diagnostic information for the client. The server may then send client-specific diagnostic messages into the SaaS pipeline for the client, the client-specific diagnostic messages causing the taps on the plurality of SaaS nodes to collect client-specific diagnostic information and send the client-specific diagnostic information to the server. The server then receives the client-specific diagnostic information from the plurality of SaaS nodes, and creates a client-specific diagnostic report based on the client-specific diagnostic information.
