Apt metrics systemd units for prometheus-node-exporter

README.md

Simple service and timer for the apt.sh metrics script from the Prometheus community script collection. Used on a Debianite system with the Debian repository version of node-exporter, YMMV. puppet/prometheus uses node-exporter as the group by default, can be changed by setting prometheus::node_exporter::group via hiera/resource parameter. Alternative uses with ACLs are possible; one would have to investigate if the DynamicUser overlay would work for deleting files from a directory.
