 The execution may be parameterized by the following environment variables:
-* SLEEPTIME           between executions (default 30 seconds)
-* NUM_LOOPS           number of repetitions (default 10)
-* THREADS             concurrent benchmarking threads (default 1)
-* MAXRECURSIONDEPTH   recursion up to this depth (default 10)
-* TOTALCALLS          the duration of the benchmark (deafult 2,000,000 calls)
-* METHODTIME          the time per monitored call (default 0 ns or 500 us)

 If they are unset, the values are set via `frameworks/common-function.sh`.
 
 Typical call (using Ubuntu):

 ./gradlew assemble 
 cd frameworks/opentelemetry/ 
 ./benchmark.sh
