Problem

Three operational questions show up in a 3am incident: 'what specifically happened during last night's run' (read individual events), 'is rows_written following its normal trend' (aggregate over time and alert), and 'where in the pipeline did the request slow down' (see one logical run as a path). The section names three signal classes that answer each: logs (timestamped human-readable events), metrics (low-cardinality numerics aggregated and alerted), and traces (a path tying together the operations of one run). Pick logs, metrics, or traces by adding three destinations downstream of the transform, one per signal class, each with a tech that fits its role.
