chetanmeh opened a new issue #3917: Provide option to support static metric names
URL: https://github.com/apache/incubator-openwhisk/issues/3917
 
 
   OpenWhisk currently use dynamic metric names for some of the cases. The dynamic case has 2 variants
   
   1. Finite Bounded options - Some of the metric names have finite states like `openwhisk.counter.invoker_docker.<cmd>_start`
   2. Non bounded options - Metric names like those used for Kafka stats `openwhisk.histogram.kafka_invoker0_count` use instance id for the name. As these id can be many the metric names can be many and setup dependent.
   
   Its possible to aggregate such metrics via use of regex or wildcard. However some systems like [Datadog does not support regex][1] which makes it tricky to analyze such metrics. Suggested way is to use Tags which is supported by #3343.
   
   As a solution may be we expose another option for disabling use of dynamic names in unbounded cases and instead use tags.
