New Relic Data Plus offers powerful observability capabilities to enhance security, scale, and performance. It provides features like data export, extended data retention, logs obfuscation, FedRAMP for enabled accounts, longer-running queries, and more. Historical data exports allow users to send existing data past initial ingestion out of New Relic, offering unlimited query durations and up to 200 million data point rows. Streaming data exports, on the other hand, send data exclusively at ingestion by New Relic, allowing users to explore data in real-time. Users can export historical data using a JSON file generated via NerdGraph, while streaming data exports require setting rules via NerdGraph about specific types of data to be exported.
