Hi Jean,

As I said, there is currently only the run time available. You can print
the run time and accumulators results to std out by retrieving the
JobExecutionResult from the ExecutionEnvironment:

JobExecutionResult result = env.execute();
System.out.println("runtime: " result.getNetRuntime());
for (Map.Entry<String, Object> entry :
result.getAllAccumulatorResults().entrySet()) {
    System.out.println(entry.getKey() + ": " entry.getValue());
}

You would do that in your Flink program. You could also store metrics in
the accumulators. However, since you're trying to compare different systems
I'd advise you to use some external tools for monitoring resource usage
like Ganglia or collectd.

Best,
Max
