+## View traces
+
+Along with the logs and metrics, query tracing is exported to DataDog. From your DataDog metrics page, `APM` > `Traces` will show you a live search of ingested trace data, with each entry of the output table showing the duration of the operation.
+
+Clicking on an entry from the table will show the details about the trace, including a flame graph, which contains a visual representation of where the operation spent its execution over time. For example, in this case a query took 2.31 milliseconds in total, of which 758 microseconds was the actual Postgres database processing the query.
