Prometheus and OpenTelemetry are two prominent open-source observability projects under the Cloud Native Computing Foundation (CNCF).

Distributed Tracing, Logs, and Metrics with OpenTelemetry

OpenTelemetry(GitHub)⮳ is a complete observability framework suitable for monitoring microservices and "cloud-native", modern, distributed systems. It is compatible with most major OSS and commercial backends. OpenTelemetry is a collection of APIs, SDKs, and tools to instrument, generate, collect, and export metrics, logs, and traces to help analyze your software's performance and behavior. Distributed tracing, a key aspect of observability, enables developers to track and analyze requests spanning multiple services.

The opentelemetry crate is an OpenTelemetry API for Rust.

• Jaeger⮳ is a Cloud Native Computing Foundation (CNCF) open-source, end-to-end distributed tracing system built for monitoring and troubleshooting microservices-based architectures. Usually incorporated as an OpenTelemetry backend, it is used to track and visualize user request behavior across the distributed components of complex systems.
• Zipkin⮳ is a distributed tracing system.

Metrics with Prometheus

Prometheus instrumentation library for Rust applications. Prometheus is an open-source systems monitoring and alerting toolkit. Prometheus's main features are:

• a multi-dimensional data model with time series data identified by metric name and key/value pairs
• PromQL, a flexible query language to leverage this dimensionality
• no reliance on distributed storage; single server nodes are autonomous
• time series collection happens via a pull model over HTTP
• pushing time series is supported via an intermediary gateway
• targets are discovered via service discovery or static configuration
• multiple modes of graphing and dashboarding support

OpenObserve

OpenObserve⮳ (written in Rust) is a petabyte-scale Elasticsearch / Splunk / DataDog alternative for logs, metrics, traces, RUM (Real User Monitoring), error tracking, and session replay.
