The hermes-otel project provides a robust OpenTelemetry (OTel) plugin designed specifically for the Hermes Agent. This plugin automatically captures and exports critical LLM operation data, including tool calls, model invocations, and API requests, as OTel spans. This enables comprehensive observability and distributed tracing for Hermes Agent workflows. It supports a wide array of OTLP-compatible backends, having been rigorously tested with popular platforms such as Arize Phoenix, Langfuse, LangSmith, SigNoz, Jaeger, Grafana Tempo, Grafana LGTM, Uptrace, OpenObserve, and Honeycomb. The plugin offers flexible configuration options, allowing users to select a single backend via environment variables or fan out to multiple backends simultaneously through a `config.yaml` file. Installation is straightforward using the `hermes plugins install` command, followed by installing necessary OTel dependencies into the Hermes Agent's virtual environment. The project also features a comprehensive testing suite, including unit, integration, and end-to-end tests that demonstrate functionality with real LMs and OTel backends, ensuring reliability and compatibility. This plugin is essential for developers seeking to gain deeper insights into the performance and behavior of their LLM-powered applications built with Hermes Agent, providing critical observability for debugging, performance optimization, and monitoring.
