This is a pretty n00b question even though I'd consider myself a pretty experienced DevOps and site reliability engineer. I've setup New Relic on our EC2 servers and have a lot of serverless metrics going to NR from AWS. I've also built some custom metrics for New Relic.
We recently started using a new tech called Rockset which is pretty cool. It has an endpoint for metrics collection. This endpoint spits out some metrics data in a portable known format - OpenMetrics/prometheus. Cool I get that so far. However I'm looking through the NR documentation and it's talking about setting up Kubernetes clusters? And/or a NR agent? The agent moves the data? Why would I need a huge cluster? For moving a ton of telemetry data? It's my goal to visualize this data in New Relic.
