UpDownCounter is a synchronous
instrument and very similar to Counter except that Add(increment)
supports negative increments. It is generally useful for capturing changes
in an amount of resources used, or any quantity that rises and falls
during a request.
Example uses for UpDownCounter:</p>
<ol>
<li> count the number of active requests. </li>
<li> count memory in use by instrumenting new and delete. </li>
<li> count queue size by instrumenting enqueue and dequeue. </li>
<li> count semaphore up and down operations. </li>
