I've used the Accumulo Tracer API before to help identify bottlenecks in my scans. You can find the most recent traces in the Accumulo Monitor UI, and there are also some tools you can use to view the contents of the trace table. See section 18.10.4 "Viewing Collected Traces" at https://accumulo.apache.org/1.9/accumulo_user_manual.html.
