What Is Remote Write?
Remote write is a protocol by which a local metrics collector forwards each batch of samples to an external, often centralized, storage system as they are gathered. It lets lightweight agents handle scraping while a scalable backend handles retention and querying. The collector buffers and retries so transient network issues do not drop data.
Why it matters
Local collectors are not built for long retention or cross-team querying. Remote write ships their data to durable central storage, enabling global dashboards without overloading the collectors.
