Re: Using "dbl" instead of "num" in SumStats

Hi Jim,

I think 'num' field seemed like what I am looking for. However, when I
tried, it is different from the count that I manually made. Here is the
codes that I used to count. As you can see, what I try to is easy,
whenever, an observation is received, I increase the value of a global
value. However, when I print out through epoch call back function, the
value is different from one in 'num'.

if (...)
     {
     total_res = total_res + 1;
     SumStats::observe("dnp3 rtt", SumStats::Key(),
SumStats::Observation($dbl=latency));
     }


Best,

Hugo
