TRACING
It can be difficult to determine why some operations are taking longer than
expected. For example, you may be looking up items with very low latency, but
sometimes the lookups take much longer. Determining the cause of the delay is
difficult because the system is distributed, and the typical lookup is fast.
Accumulo has been instrumented to record the time that various operations take
when tracing is turned on. The fact that tracing is enabled follows all the
requests made on behalf of the user throughout the distributed infrastructure
of Accumulo, and across all threads of execution.

and the user manual makes no mention of the facility, its defaults, how to
configure it, nor how to leverage it in ops.
