I am making early attempts at gathering metrics around methods and sql calls. I 
am using the Snapshot  Reporter to send metrics to a kafka topic. The docs 
state that metrics are sent to kafka every 60 seconds 
(https://samza.apache.org/learn/documentation/latest/container/metrics.html).


When I am instrumenting a method via Timer.update() which is called n-number of 
times in 60 seconds am I seeing an aggregation of the time spent in said method 
during a 60 second period or am I seeing the last value sent through 
Timer.update()?
