SystemD service configuration

Service systemd files are in /usr/lib/systemd/system/ or /etc/systemd/, and their content format is similar to a ‘.ini’ file.

Parsers included in this module are:

SystemdDocker - file /usr/lib/systemd/system/docker.service

SystemdLogindConf - file /etc/systemd/logind.conf

SystemdRpcbindSocketConf - unit file rpcbind.socket

SystemdDnsmasqServiceConf - unit file dnsmasq.service

SystemdOpenshiftNode - file /usr/lib/systemd/system/atomic-openshift-node.service

SystemdSystemConf - file /etc/systemd/system.conf

SystemdOriginAccounting - file /etc/systemd/system.conf.d/origin-accounting.conf
