When deciding for a metrics tooling, one of the implicit decisions we take is about the temporality: are we capturing, exporting, and storing metrics that send only the difference between states (deltas), or are we picking a solution that works by accumulating data instead? In this talk, Tom Braack will show how to migrate from delta-style backends to cumulative ones, with a special focus on doing translations at the Collector side. Join us on this session and be equipped with knowledge about how to move from delta backends to cumulative ones, knowing what are the tradeoffs and gotchas.
