LoongSuite Hermes Agent instrumentation

LoongSuite Hermes Agent Instrumentation

LoongSuite instrumentation for Hermes Agent.

Features

• Agent tracing: invoke_agent Hermes spans for top-level agent runs
• ReAct step tracing: react step spans for each Hermes reasoning round
• LLM tracing: model request/response spans with token usage and TTFT
• Tool tracing: execute_tool spans for Hermes tool calls
• Content capture controls: honors OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT

Installation

# Step 1: install LoongSuite distro
pip install loongsuite-distro

# Step 2 (Option C): install this instrumentation from PyPI
pip install loongsuite-instrumentation-hermes-agent

# Optional app dependency
pip install hermes-agent

Usage

Auto-instrumentation

export OTEL_SEMCONV_STABILITY_OPT_IN=gen_ai_latest_experimental
export OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT=SPAN_ONLY

loongsuite-instrument python your_hermes_app.py

Manual instrumentation

from opentelemetry.instrumentation.hermes_agent import HermesAgentInstrumentor
from run_agent import AIAgent

HermesAgentInstrumentor().instrument()

agent = AIAgent(
    model="qwen-turbo",
    provider="dashscope",
    quiet_mode=True,
)
result = agent.run_conversation("Hello from Hermes")

HermesAgentInstrumentor().uninstrument()

Configuration

Export to OTLP Backend

export OTEL_SERVICE_NAME=my-hermes-app
export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
export OTEL_EXPORTER_OTLP_TRACES_ENDPOINT=<trace_endpoint>
export OTEL_EXPORTER_OTLP_METRICS_ENDPOINT=<metrics_endpoint>

loongsuite-instrument python your_hermes_app.py

Content Capture

export OTEL_SEMCONV_STABILITY_OPT_IN=gen_ai_latest_experimental

# Capture content in spans only
export OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT=SPAN_ONLY

# Disable content capture
export OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT=NO_CONTENT

Supported Signals

• AGENT: top-level Hermes agent invocation
• ENTRY: AI application entry spans when Hermes resolves an entry source from AIAgent.platform, HERMES_SESSION_SOURCE, or the default cli source used by platform-less AIAgent instances. Every top-level instrumented AIAgent.run_conversation now emits ENTRY -> AGENT.
• STEP: Hermes ReAct step lifecycle
• LLM: synchronous and streaming model calls
• TOOL: Hermes tool execution, including tool call id, arguments, and result
