N+1 Detection in AppSignal's OpenTelemetry Trace Timeline

AppSignal has added N+1 query detection to its OpenTelemetry support. When the pattern is identified in a trace, repeated spans are automatically collapsed into a single grouped entry showing count and cumulative cost, making the performance issue immediately visible without requiring a context switch. OpenTelemetry itself only records spans faithfully without analyzing patterns, so AppSignal fills that gap by running analysis on top of the raw span data. The feature is available on all plans and was released March 11, 2026.
