Grafana Version = 12.3.0 and Tempo Version = 2.9
Using TraceQL, I am attempting to group similar values in the akka.actor.path attribute and retrieve the corresponding count. Although data exists for this attribute, executing the query below results in “No Data” being displayed in Grafana. I would like to understand why the query returns no results and how to correctly group similar actor path names while obtaining the count.
Note: In TraceQL, aggregation functions such as count(), quantile_over_time(), histogram_over_time(), and most other aggregation queries are consistently returning “No Data” in Grafana, despite the underlying trace data being present. This issue occurs across multiple aggregation types, and I am seeking clarification on why these aggregations are not producing results and how they can be correctly configured to return data.
If anyone is aware of a solution to this issue, please let me know at the earliest.
