Not really available, but sampled to make statistics.

I don't think so. Each variable will be correct and is not supposed to be
related to another one (this is a false assertion if your point of view is
debugging). The script will run for example with a cycle of 10 s (as collectd
did) to give trends, no more, no less.
Then it's up to you to read the log to search for correlation if trends are
curious, it's just monitoring! But (I hope) it may be a good help for people
having many servers running Nginx.
