Histogram type allows only one set of Buckets or Quantiles for all the prometheus listeners #126

Closed AntonNaumovski closed 12 months ago

When using the Histogram Type, only one unique set of defined Buckets or Quantiles is accepted for all the prometheus listeners in a test plan. For ex: if you have Prometheus listener and Histogram configured to measure ResponseTime with Buckets: 100,500,1000,3000,4000 and create another listener on a different request in the thread with different set of buckets, the former one will be omitted from the prometheus formatted output.

Plugin version 0.6.2 is being used..

Found it myself: if different sets of buckets are used, the metric_name i.e Name in the listener should be different.

Thanks for the ticket! Yes metric_name has to be unique across listeners because there's a global Prometheus thing we're registering the histogram with.
