Re: Metrics for average time taken by flatMap function

Sure, that might work. Be aware though that time measurements are, 
compared to the logic within a function, usually rather expensive and 
may impact performance.

Hi All,
I have implemented a flatmap function and I want to collect metrics 
for average time for this function which I plan to monitor via prometheus.

What would be good approach for it? I have added a gauge to the 
method(extending Gauge interface from flink API). Would it work for my 
needs?
