要这样做，拷贝一个现有的报告显示入口然后改变数值以符合你的需要。

To do this, copy an existing report manifest entry and change the values to suit your needs. For example.

youdao

特别的是，规格必须需要元数据来提供上下文，换句话说就是当收集元数据时，如何来收集以及如何来改变数值。

Metrics in particular need metadata to provide context, in other words, when it was collected, how it was collection, how it changes value.

youdao

做这个的方式是，我不仅仅要通过提前定义好的方法，来改变数值，我还应该通过提前定义好的方法，来读这个值，我应该用。

A good, hygienic way of doing this is, not only do I not go in and change things except through a pre-defined method, I shouldn't read it other Cartesian than through a pre-defined method.

youdao

Along the way I have some tests, and depending on the value of that test, I may change where I am in that sequence of instructions.

我会按顺序进行一些测试，按照测试的数值，我会改变之指令序列中,我的位置。

Don't go in and change the values of things by using the direct access.

也就是别这么做,别直接去访问,并改变实例中的数值。
