OpAMP Rust

The Open Agent Management Protocol (OpAMP) is a network protocol for remote management of agents. This project aims to implement the OpAMP protocol in a client library that can be used by Supervisor processes. By leveraging Rust's memory safety and performance, we aim to provide a reliable and efficient way of transmitting observability metrics.

Getting Started

This library is published as a standard crate. To add it to your project, include it as a dependency inside Cargo.toml like so:

otel-opamp-rs = { version = "0.0.8", features = ["http", "websocket", "extras"] }

For more details refer to the API documentation


This library supports the following capabilities

  • HTTP support
  • Websocket support
  • Gzip compression
  • Low resource consumption

The code references stable releases of the OpAMP protocol protobuf definition here and aims to be standards compliant on behavior to the published OpAMP specification


This code uses the current stable release of Rust.

To checkout and build the code do the following:

git clone --recursive git@github.com:newrelic/otel-opamp-rs.git
cargo build


This library is owned and maintained by members of the CA organization within New Relic. The authors will respond to bug reports and feature requests on a prioritized basis.
