Use the /alibabacloud-livedebug Skill to add a dynamic log at the exit of OrderService.create_order in app.service.order, print order_id, amount, return value, and latency. Keep it for 30 minutes.

{
  "probeType": "LOG",
  "language": "python",
  "target": {
    "typeName": "app.service.order",
    "methodName": "OrderService.create_order",
    "location": "exit",
    "instanceIds": ["*"]
  },
  "action": {
    "type": "LOG",
    "template": "create_order id={order_id} amount={amount} ret={@return} cost={@duration}ms"
  },
  "ttl": "30m",
  "captureCount": 100
}

Add a log at line 42 of app/service/order.py. Only output the order ID and amount when amount >= 1000.

{
  "probeType": "LOG",
  "language": "python",
  "target": {
    "sourceFile": "app/service/order.py",
    "location": "line:42",
    "instanceIds": ["*"]
  },
  "trigger": {
    "condition": "amount >= 1000"
  },
  "action": {
    "type": "LOG",
    "template": "big order id={order_id} amount={amount}"
  },
  "ttl": "30m"
}

Use the /alibabacloud-livedebug Skill to take a snapshot at the exit of OrderService.create_order. Capture input parameters, local variables, return value, and call stack. Capture up to 20 times.

{
  "probeType": "SNAPSHOT",
  "language": "python",
  "target": {
    "typeName": "app.service.order",
    "methodName": "OrderService.create_order",
    "location": "exit",
    "instanceIds": ["*"]
  },
  "action": {
    "type": "SNAPSHOT",
    "capture": ["ARGS", "LOCALS", "RETURN", "STACK"],
    "captureConfig": {
      "maxDepth": 3,
      "maxCollectionSize": 100,
      "maxStringLength": 1024
    }
  },
  "ttl": "30m",
  "captureCount": 20
}

Take a snapshot at the exit of create_order. Trigger only when the return value is empty or the amount is greater than 10000. Focus on order_id, amount * count, self.user_id, and the return value.

{
  "probeType": "SNAPSHOT",
  "language": "python",
  "target": {
    "typeName": "app.service.order",
    "methodName": "OrderService.create_order",
    "location": "exit",
    "instanceIds": ["*"]
  },
  "trigger": {
    "condition": "@return is None or amount > 10000"
  },
  "action": {
    "type": "SNAPSHOT",
    "capture": ["ARGS"],
    "captureExpressions": [
      "order_id",
      "amount * count",
      "self.user_id",
      "@return"
    ]
  },
  "ttl": "30m",
  "captureCount": 50
}

Capture a snapshot when PaymentService.process_payment throws an exception. Include input parameters, exception information, and call stack. Keep it for 2 hours.

{
  "probeType": "SNAPSHOT",
  "language": "python",
  "target": {
    "typeName": "app.service.payment",
    "methodName": "PaymentService.process_payment",
    "location": "exception",
    "instanceIds": ["*"]
  },
  "action": {
    "type": "SNAPSHOT",
    "capture": ["ARGS", "EXCEPTION", "STACK", "LOCALS"]
  },
  "ttl": "2h",
  "captureCount": 100
}

Use the /alibabacloud-livedebug Skill to add an amount histogram metric to create_order. Include a tag indicating whether the user is a VIP. Keep it for 1 hour.

{
  "probeType": "METRIC",
  "language": "python",
  "target": {
    "typeName": "app.service.order",
    "methodName": "OrderService.create_order",
    "location": "exit",
    "instanceIds": ["*"]
  },
  "action": {
    "type": "METRIC",
    "metricName": "livedebug.order.amount",
    "metricType": "HISTOGRAM",
    "valueExpression": "amount",
    "tags": {
      "is_vip": "str(user_id == 'vip')"
    }
  },
  "ttl": "1h"
}

Use the /alibabacloud-livedebug Skill to temporarily add a span on OrderService.create_order named dyn.create_order. Include the order ID and amount as span attributes.

{
  "probeType": "SPAN",
  "language": "python",
  "target": {
    "typeName": "app.service.order",
    "methodName": "OrderService.create_order",
    "location": "enter",
    "instanceIds": ["*"]
  },
  "action": {
    "type": "SPAN",
    "spanName": "dyn.create_order",
    "spanTags": {
      "order.id": "str(order_id)",
      "order.amount": "str(amount)"
    }
  },
  "ttl": "1h"
}

At the exit of create_order, use the /alibabacloud-livedebug Skill to tag the current span with order.id and order.result (use the return value). Do not create a new span.

{
  "probeType": "SPAN_TAG",
  "language": "python",
  "target": {
    "typeName": "app.service.order",
    "methodName": "OrderService.create_order",
    "location": "exit",
    "instanceIds": ["*"]
  },
  "action": {
    "type": "SPAN_TAG",
    "tags": [
      {"key": "order.id", "value": "str(order_id)"},
      {"key": "order.result", "value": "str(@return)"}
    ]
  },
  "ttl": "1h"
}

Show me what Live-Debug agents are still attached to the current service. If there are any, delete all of them.
