ngxtop can't parse old logs (output is messed)

[tchwpkgorg]

ngxtop is a nice tool, but I don't see a way to use it for old logs - while it does show the output nicely during log parsing, the output is garbled when log parsing finishes - see below for an example.

It would be nice if ngxtop had some kind of CSV/table/text output for such cases.

cat some-old-log | ngxtop

Ugh, I've missed "--no-follow" option which does exactly what I want.
