[Nix-dev] log checker

[Mathijs Kwik]

Hi all,

I'm looking for a package to monitor system logs for abnormalities
(hardware issues, attacks, daemon notices) and sends out emails about
these (immediately, or digested once a day, depending on the perceived
importance of the log message).

I've used "logcheck" in the past on debian, but I couldn't find that in nixpkgs.
Before I dive into packaging that, I would like to know what others
use for this purpose.

Thanks,
Mathijs
