Log systemd service state changes using rsyslog.
systemctl to get process identifier for specified service.
Manage systemd services remotely over SSH protocol.
Monitor file system events to restart service on every configuration change.
varnishlog to log specific Varnish requests.

Configure systemd service to be restarted in case of failure.
Unmount not accessible NFS share that still has open files.
