cloudbase-agent-observability 0.1.2

OpenTelemetry-based observability for Cloudbase Agent Python SDK with OpenInference semantic conventions

Python Observability

OpenTelemetry-based observability for the Python SDK with OpenInference semantic conventions.

✨ Key Features

• 🔌 Optional Configuration - Enable stdout export via AUTO_TRACES_STDOUT=true (default: disabled)
• 🎯 OpenInference Compatible - Follows OpenInference semantic conventions for AI/LLM tracing
• 🔗 Full Span Hierarchy - Captures AG-UI.Server → Adapter → Framework → LLM/Tool spans
• 🚀 Built-in Configuration API - Simple ConsoleTraceConfig() / OTLPTraceConfig() setup
• 📊 OTLP Export - Works with Langfuse, Jaeger, and any OTLP-compatible backend
• ⚡ Hybrid Mode - Combine ENV console export with parameter OTLP export

---

🚀 Quick Start

Option 1: Built-in Configuration (Recommended)

from cloudbase_agent.server import AgentServiceApp
from cloudbase_agent.observability.server import ConsoleTraceConfig

app = AgentServiceApp(observability=ConsoleTraceConfig())
app.run(create_agent, port=8000)

Option 2: AUTO_TRACES_STDOUT (Zero Code)

export AUTO_TRACES_STDOUT=true
python your_agent.py

Option 3: OTLP Export (Langfuse, etc.)

from cloudbase_agent.server import AgentServiceApp
from cloudbase_agent.observability.server import OTLPTraceConfig

app = AgentServiceApp(
    observability=OTLPTraceConfig(
        url="https://cloud.langfuse.com/api/public/otlp/v1/traces",
        headers={"Authorization": "Basic <credentials>"}
    )
)
app.run(create_agent, port=8000)

Option 4: Hybrid (ENV Console + Parameter OTLP)

import os
os.environ["AUTO_TRACES_STDOUT"] = "true"  # Console from ENV

from cloudbase_agent.server import AgentServiceApp
from cloudbase_agent.observability.server import OTLPTraceConfig

app = AgentServiceApp(
    observability=OTLPTraceConfig(url="...")
)
# Both console (from ENV) and OTLP (from param) receive traces!
app.run(create_agent, port=8000)

---

📦 Installation

# Install observability package
pip install cloudbase-agent-observability

# Or with adapter
pip install cloudbase-agent-langgraph[observability]
pip install cloudbase-agent-crewai[observability]

🛠️ Configuration API

Configuration Types

Type	Description
ConsoleTraceConfig()	Export to stdout (JSON format)
OTLPTraceConfig(url=...)	Export to OTLP backend
CustomTraceConfig(setup=fn)	Custom setup function
BatchConfig()	Batch processing options

ConsoleTraceConfig

from cloudbase_agent.observability.server import ConsoleTraceConfig, BatchConfig

# Default console export
config = ConsoleTraceConfig()

# With custom batch settings
config = ConsoleTraceConfig(
    batch=BatchConfig(max_export_batch_size=200)
)

OTLPTraceConfig

from cloudbase_agent.observability.server import OTLPTraceConfig

config = OTLPTraceConfig(
    url="https://cloud.langfuse.com/api/public/otlp/v1/traces",
    headers={"Authorization": "Basic <credentials>"},
    timeout=10000,
)

CustomTraceConfig

from cloudbase_agent.observability.server import CustomTraceConfig

def my_setup():
    # Your custom OTel setup
    ...

config = CustomTraceConfig(setup=my_setup)

---

📋 Usage Examples

LangGraph

from cloudbase_agent.server import AgentServiceApp
from cloudbase_agent.langgraph import LangGraphAgent
from cloudbase_agent.observability.server import ConsoleTraceConfig

app = AgentServiceApp(observability=ConsoleTraceConfig())
app.run(lambda: {"agent": LangGraphAgent(graph=workflow.compile())}, port=8000)

CrewAI

import os
os.environ['CREWAI_DISABLE_TELEMETRY'] = 'true'  # Before CrewAI imports!

from cloudbase_agent.server import AgentServiceApp
from cloudbase_agent.crewai import CrewAIAgent
from cloudbase_agent.observability.server import ConsoleTraceConfig

app = AgentServiceApp(observability=ConsoleTraceConfig())
app.run(create_agent, port=8000)

---

🔧 Advanced: Manual TracerProvider

For advanced use cases requiring custom TracerProvider:

from opentelemetry import trace
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import ConsoleSpanExporter, BatchSpanProcessor
from opentelemetry.sdk.resources import Resource

resource = Resource.create({"service.name": "my-app"})
provider = TracerProvider(resource=resource)
provider.add_span_processor(BatchSpanProcessor(ConsoleSpanExporter()))
trace.set_tracer_provider(provider)

app = AgentServiceApp()  # Will use your provider
app.run(create_agent, port=8000)

Note: This bypasses the built-in configuration API. Use only when necessary.

📊 Span Hierarchy Example

AG-UI.Server
  └─ Adapter.LangGraph
      └─ LangGraph
          ├─ node_a
          │   └─ ChatOpenAI
          └─ node_b
              └─ ChatOpenAI

🆚 Built-in vs Manual

Aspect	Built-in API	Manual Setup
Lines of code	1-2	20+
Type safety	✅	❌
Batch defaults	✅ Optimized	❌ Manual
Multiple exporters	✅ Array	❌ Complex
ENV support	✅ AUTO_TRACES_STDOUT	❌

Migration:

# Before (Manual)
from opentelemetry import trace
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import ConsoleSpanExporter, BatchSpanProcessor
from opentelemetry.sdk.resources import Resource

resource = Resource.create({"service.name": "my-app"})
provider = TracerProvider(resource=resource)
provider.add_span_processor(BatchSpanProcessor(ConsoleSpanExporter()))
trace.set_tracer_provider(provider)
app = AgentServiceApp()

# After (Built-in)
from cloudbase_agent.server import AgentServiceApp
from cloudbase_agent.observability.server import ConsoleTraceConfig

app = AgentServiceApp(observability=ConsoleTraceConfig())
