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