Observability Doctor

Check environment setup for tools: 
# Check all tools
praisonai-ts observability doctor

# Check specific tool
praisonai-ts observability doctor langfuse
praisonai-ts observability doctor langsmith
praisonai-ts observability doctor arize

# JSON output
praisonai-ts observability doctor langfuse --json
Example Output (specific tool): 
Observability Doctor: langfuse
  Description: Langfuse LLM observability
  Package: langfuse
  Environment Variable: LANGFUSE_SECRET_KEY
  Status: ❌ Missing API Key

  Set the API key with:
    export LANGFUSE_SECRET_KEY=your-api-key

  Features:
    Traces: ✅  Spans: ✅  Events: ✅
    Errors: ✅  Metrics: ✅  Export: ✅
Example Output (all tools): 
Observability Environment Check

  Total Tools: 17
  Ready: 3 ✅

  Ready Tools:
    ✅ console
    ✅ memory
    ✅ noop

​
Observability Test

Test a tool with a real trace: 
# Test built-in tools (no API key needed)
praisonai-ts observability test memory
praisonai-ts observability test console

# Test external tools (requires API key)
praisonai-ts observability test langfuse
praisonai-ts observability test langsmith

# JSON output
praisonai-ts observability test memory --json
Example Output: 
Testing memory observability...

  ✅ Test Passed
  Tool: memory
  Latency: 2ms
  Trace ID: abc123xyz
JSON Output: 
{
  "success": true,
  "data": {
    "tool": "memory",
    "status": "success",
    "latency_ms": 2,
    "trace_id": "abc123xyz"
  }
}

Troubleshooting

​
Missing API Key

# Check which keys are missing
praisonai-ts observability doctor

# Check specific tool
praisonai-ts observability doctor langfuse
# Output: ❌ Missing API Key
# Set it with: export LANGFUSE_SECRET_KEY=your-api-key

​
Tool Not Available

# Check if tool package is installed
praisonai-ts observability doctor langfuse
# If package missing, install with:
# npm install langfuse

​
Test Failures

# Run test with verbose output
praisonai-ts observability test langfuse --verbose

# Check JSON error details
praisonai-ts observability test langfuse --json

​
SDK Usage

For programmatic observability: 
import { 
  createObservabilityAdapter, 
  setObservabilityAdapter,
  OBSERVABILITY_TOOLS,
  listObservabilityTools 
} from 'praisonai';

// List all tools
const tools = listObservabilityTools();
console.log(tools.map(t => t.name)); // ['langfuse', 'langsmith', ...]

// Create adapter
const obs = await createObservabilityAdapter('langfuse');
setObservabilityAdapter(obs);

// Use with agents
const agent = new Agent({
  instructions: 'You are helpful.'
});
await agent.chat('Hello');

// Flush traces
await obs.flush();
