New Relic
Platform & Telemetry Data Platform
See how New Relic funnels every signal into one database queried by NRQL.
New Relic is a SaaS observability platform whose defining idea is a single telemetry database. Metrics, events, logs, and traces — the "MELT" signals — all land in NRDB, the New Relic Database, as events with attributes. Because everything shares one store and one query language, you are not stuck switching tools to correlate a log with a trace or a metric; you query across them in NRQL.
One giant searchable journal where every kind of note — receipts, photos, letters — is filed in the same book with tags, so any cross-reference is just another search rather than opening five filing cabinets.
Key Concepts
1
Data arrives through language agents (APM, browser, mobile), infrastructure agents, and open standards: New Relic ingests OpenTelemetry and Prometheus remote_write directly. Pricing is consumption-based — you pay for data ingested (per GB) and for the users who query it, rather than per host — which changes how teams think about what to send. The platform layers curated experiences (APM, infrastructure, logs, browser/RUM, synthetics) on top of that one database.

1. "What is distinctive about New Relic's data model?" *Probing:* the architecture. *Stalls:*
"It stores data." *Moves up:* one telemetry database holding events, metrics, logs and traces, all
queryable with NRQL rather than four separate systems.

2. "What is an event versus a metric here?" *Probing:* the distinction. *Stalls:* "Nothing."
*Moves up:* an event is a timestamped record with attributes retained in detail; a metric is
aggregated numeric data retained longer and more cheaply.

3. "How is it priced?" *Probing:* the commercial understanding. *Stalls:* "Per host." *Moves
up:* by data ingested and by user seat, which changes the optimisation from host count to what you
choose to send.

4. "What is the practical implication of that pricing?" *Probing:* the follow-up. *Stalls:*
"None." *Moves up:* drop rules and sampling at the edge matter — sending everything and filtering
later is paid for twice.
