[collectd] Remind: Does regex match end of a line?

[Denis Melnikov]

Hi, all!
Using tail plugin I want to speed up regex matching via anchoring to
end-of-line with '$'.
But as I can see, the plugin evaluates '$' sign as something else, maybe
literal '$'.
Is it possible to use '$' sign as anchor to end-of-line?
I.e.:

Regex " 200 ([0-9]+\\.[0-9]+)$"

Sincerely,
Denis
