elastic-apm-http-client

A low-level HTTP client for communicating with the Elastic APM intake API. Version 12.0.0 supports the intake API v2 (for v1 use <6.x). It handles ndjson serialization, gzip compression, and streaming to the APM Server. Designed as a building block for custom APM agents, not for direct use in applications; the official Elastic APM Node.js agent is recommended instead. Released under MIT license, with frequent updates.
