Something that looks vaguely similar to lnav (and Angle Grinder) is fzf (https://github.com/junegunn/fzf). It's quite good at interactively searching for given items in a pile of text.

I don't think it does summing "out of the box", but I've found it great for exploring logs (or even very long grep searches) interactively.

In the past I've used RecordStream a lot. I don't really know Perl but recs is still damn useful.
