I am very happy to submit a package for reed-alert. It's a software to monitor servers (file creation, ssl certificate expiration, service running, load, etc...) easily. So much enthousiasm comes from that I'm the author of it and making it packageable AND portable wasn't straightforward.
It doesn't track any value nor produce graphs, it only check if things works. It only uses a ~/.reed-alert/states folder to keep track of check reporting failures, so you can be warned after N failures (to prevent false positives) and to warn you when it doesn't fail anymore. Examples and a full README (the documentation) are packaged. One check available uses curl so I added net/curl in RUN_DEPEND, it also requires either lang/ecl or lang/sbcl for running. I choose to use lang/ecl as RUN_DEPENDS as it has a smaller memory footprint and doesn't require W^X. I hold a talk about it at BitreichCON 2018: https://dataswamp.org/~solene/2018-08-20-brcon2018-reed-alert.html
