推荐答案

如果有这样的事情，我不确定这是否是官方定义"，但是我已经使用深层ping"来了解允许您使用的功能(与常规ping相反)向服务器发送一条消息，该消息使 尽可能多地通过Web堆栈 ，然后返回确定"响应.

I'm not sure it's the "official definition" if there is such a thing, but I've head "deep ping" used about functionality that allows you to (in contrast to a regular ping) send a message to the server that passes through as much of the webstack as possible before returning an "ok" response.

作为一个例子，您可以进行一个ping事务，该事务从网络直接向下传递到堆栈，并进行虚拟选择，以从虚拟表中读取ok并返回该结果.与仅测试网络的普通ping"相反，这使您可以放心应用程序中的所有层(包括数据库)实际上仍处于活动状态.

As an example, you can make a ping transaction that passes from the network straight down the stack to the database and there does a dummy select to read the ok from a dummy table and return that result. That allows you to (in contrast to a "normal ping" that tests only the network) have confidence that all layers in the application including the database are actually alive.
