Removal of ‘Aggregate by’ in Tempo
Removal of ‘Aggregate by’ in Tempo
Aggregate by was introduced as a way to view RED metrics for your traces in the Tempo data source. This functionality has been deprecated since Grafana v11.3 in favor of using Traces Drilldown and the TraceQL metrics API, which offers much more functionality and complex features. Additionally, TraceQL metrics queries are significantly more powerful than what the metrics summary API provides.
Migration/mitigation
RED metrics are supported via Traces Drilldown and can be viewed with more advanced context than via the older metrics summary API. For all users, the aggregate by section will no longer be present in the Tempo data source search tab. Additionally, any user that had been using the aggregate by functionality in the Tempo data source in a dashboard can manually change the Tempo query.
