vvraskin opened a new pull request #3423: Measure kafka queue in consumer with better exactitude
URL: https://github.com/apache/incubator-openwhisk/pull/3423
 
 
   Measure kafka queue metric directly in the consumer by comparing the offsets instead of relying on the built-in consumer metrics. This method provides more precision compared to the old approach, it was observed that the built-in metrics show certain lagging in case of burst. 
   Additionally make kamon flush cadency configurable in the application.conf.
