what is deep_ping [closed]

Question

I am not sure if this is the correct forum to ask this but i am not sure where to ask either. So here is my question:

what does "deep ping" mean. I tried google but still did not get any information about it. Also who does deep ping mean in web servlet`s context. Thanks.

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.

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.
