How do I Monitor Tool Calls in My AI Agents?

const toolCall = trace.toolCall({
  id: 'database-query-001',
  name: 'query_user_database',
  description: 'Queries the user database for customer information',
  args: JSON.stringify({
    userId: '12345',
    fields: ['name', 'email', 'preferences']
  }),
});

tool_call = trace.add_tool_call({
    "id": "database-query-001",
    "name": "query_user_database",
    "description": "Queries the user database for customer information",
    "args": json.dumps({
        "userId": "12345",
        "fields": ["name", "email", "preferences"]
    }),
})

// Execute and record result
try {
  const userData = await queryDatabase(toolCallArgs);
  toolCall.result(JSON.stringify(userData));
} catch (error) {
  toolCall.error({
    message: error.message,
    code: 'DB_CONNECTION_ERROR',
    type: 'DatabaseError'
  });
}

# Execute and record result
try:
    user_data = query_database(tool_call_args)
    tool_call.result(json.dumps(user_data))
except Exception as e:
    tool_call.error({
        "message": str(e),
        "code": "DB_CONNECTION_ERROR",
        "type": "DatabaseError"
    })

toolCall.addTag('environment', 'production');
toolCall.addTag('user_type', 'premium');

toolCall.addMetadata({
  requestId: 'req-123',
  processingTime: 1500,
  retryCount: 0
});
