Delta Values

[Olivier Arbey]

Hello,

I was recommended to come over here for this question. We are using DropWizardMetrics in our ratpack application. Currently, we only get aggregated, cumulative metrics since the start of the application.We are trying to configure it to report only delta metrics, e.g. metrics for the last 5 minutes.Could someone points me in the right direction on how to achieve this ?

TIA,

Olivier

This comes up often. There isn’t a great way at the moment; we hope to have ways to represent this better in metrics v4.

For Histogram-backed metric types, the ResetOnSnapshot variant available at https://bitbucket.org/marshallpierce/hdrhistogram-metrics-reservoir may be useful (primarily of interest if you have only one reporter, due to the way snapshots currently work).
