Favorite (rpm-ostree friendly) monitoring tools?



I need to monitor the availability and vulnerabilities in some devices on my network and I would like to do that from Fedora Atomic Server (fc29) what do people recommend?
So far I have looked at OpenNMS and OpenVas (atomicorp, GSA) but they don’t have very current packaging and I have trouble installing them (I need to run them as root).
Perhaps Zabbix or Nagios are more friendly? is there a similar package that is current with fedora packaging?
