yr.DoubleCounter.add_labels

DoubleCounter.add_labels(labels: dict) → None

为 metrics 数据添加标签。

参数：

• value (float) - 要添加的标签字典。

异常：

• ValueError - 如果标签为空。

样例：

>>> import yr
>>>
>>> config = yr.Config(enable_metrics=True)
>>> yr.init(config)
>>>
>>> @yr.instance
>>> class Actor:
>>>     def __init__(self):
>>>         self.data = yr.DoubleCounter(
>>>             "userFuncTime",
>>>             "user function cost time",
>>>             "ms",
>>>             {"runtime": "runtime1"}
>>>         )
>>>         self.data.add_labels({"stage": "init"})
>>>         print("Actor init:", self.data._DoubleCounter__double_counter_labels)
>>>
>>>     def run(self):
>>>         self.data.set(5)
>>>         self.data.add_labels({"phase": "run"})
>>>         msg = f"Actor run: {self.data._DoubleCounter__double_counter_labels},
>>>         value: {self.data.get_value()}"
>>>         print(msg)
>>>         return msg
>>> actor1 = Actor.options(name="actor").invoke()
>>> result = actor1.run.invoke()
>>> print("run result:", yr.get(result))
