------------------------------
Summary: Use of Average for stats
Key: JGRP-1647
URL: https://issues.jboss.org/browse/JGRP-1647
Project: JGroups
Issue Type: Enhancement
Reporter: Bela Ban
Assignee: Bela Ban
Priority: Minor
Fix For: 3.4
Use Average to maintain average values instead of maintaining separate counters (e.g.) for number of values and totals. Average is faster and total can wrap around.

Another example prone to overflow are counters of the number of bytes sent/received. Investigate use of BigInteger.

> We have some counters which might see a lot of increments. Investigate which counters are affected (and how) by a potential wraparound, e.g. longs wrap around at 2^63 and go negative.
> For example, storing delivery times in nanoseconds and totalling that number could end up with an overflow as e.g. 2ms = 2000000ns, for 1 million msgs/sec would overflow in roughly 7 weeks ! That's the reason org.jgroups.util.Average was created: instead of totalling delivery time and the number of deliveries to compute avg delivery time, we only maintain a fixed array of delivery times, and its elements are randomly overwritten with new values, so we only keep the (more or less) most recent N values to compute the average.
> Using a long for a message sequence number should not be an issue: even if we send 1 million messages / sec, we could send for roughly 290'000 years !
