Claus Ibsen reassigned CAMEL-23865:
-----------------------------------
Assignee: Claus Ibsen
> LoadThroughput should use EWMA smoothing like LoadTriplet instead of
> instantaneous delta
> ----------------------------------------------------------------------------------------
>
> Key: CAMEL-23865
> URL: https://issues.apache.org/jira/browse/CAMEL-23865
> Project: Camel
> Issue Type: Improvement
> Components: camel-management
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Major
>
> The LoadThroughput class calculates throughput as an instantaneous rate over
> the last 1-second sampling interval:
> {code}
> thp = (1000d / time) * delta;
> {code}
> This means for a route with a timer firing every 5 seconds, the throughput
> oscillates between 0.00 (4 out of 5 samples) and 1.00 (1 out of 5 samples),
> instead of showing the correct average of ~0.20 exchanges/second.
> The LoadTriplet class (used for load01/load05/load15) already uses EWMA
> (exponentially weighted moving average) modeled after Unix top load averages.
> LoadThroughput should use the same approach to produce a smoothed, accurate
> throughput value.
> This affects the exchangesThroughput value in the status JSON file, dev
> consoles, and JMX MBeans.
