Shinken is a modern open source Nagios® like tool, redesigned and rewritten from scratch. Its main goal is to meet today’s system monitoring requirements while still allowing compatibility to Nagios®.
Since the ebuilds https://bitbucket.org/heltem/overlay/src/46ed51586a13/net-analyzer/shinken/ (the only ones I could find) are a bit outdated, I created one for the current version 2.0.3 now.
It works well with USE=systemd (including systemd service files and tmpfiles.d). For systems without that, some manual creation of /var/tmp/shinken might need to be re-added.
