Why is rsyslog not listed when I run service?

I'm trying to learn about rsyslog. On one of my linux boxes, I think that rsyslog has been configured to run through systemd based on this output: >systemctl status rsyslog rsyslog.service - System Logging Service Loaded: loaded (/usr/lib/systemd/system/rsyslog.service; enabled) Active: active (running) since Tue 2017-01-10 11:28:07 PST; 3 months 19 days ago Main PID: 954 (rsyslogd) CGroup: /system.slice/rsyslog.service L954 /sbin/rsyslogd -n >ps ax | grep syslog 954 ? Ssl 6:22 /sbin/rsyslogd -n On the other linux box, though, systemv (systemctl is not present) seems unaware that rsyslogd is running: [root@box ~]# service --status-all | grep -i syslog 2>&1 [root@box ~]# ps ax | grep -i syslog 7866 ? Sl 1:49 /sbin/rsyslogd -n -c5 -i /var/run/syslogd.pid Why this disparity? On the second box, is the fact that rsyslogd is running but not "found" by service evidence that it was spawned "manually" from the command-line and not configured through one of service's init.d scripts? (Sorry if my terminology is primitive). What I actually wanted to achieve was: on the second box, I wanted to restart rsyslog, and I expected to do so by running something like service rsyslog restart. But not finding rsyslog when I ran service --status-all led me down this detour.
