Systemctl is a systemd utility that is responsible for Controlling the systemd system and service manager. Systemd is a collection of system management daemons, utilities, and libraries which serves as a replacement of System V init daemon. Systemd functions as central management and configuration platform

To list all loaded services on your system (whether active; running, exited or failed, use the list-units subcommand and --type switch with a value of service.

# systemctl list-units --type=service
OR
# systemctl --type=service

But to get a quick glance of all running services (i.e all loaded and actively running services), run the following command.

# systemctl list-units --type=service --state=running 
OR
# systemctl --type=service --state=running

List all failed units.

# systemctl --failed

Check whether a Unit or Service is running or not?.

# systemctl status httpd-e-smith

How do I start, restart, stop, reload and check the status of a service (httpd.service) in Linux.

# systemctl start httpd-e-smith.service
# systemctl restart httpd-e-smith.service
# systemctl stop httpd-e-smith.service
# systemctl reload httpd-e-smith.service
# systemctl status httpd-e-smith.service

statusreport

This service reports monthly to Koozali your Release number, current date, date of installation, aside with a hash of your System ID created at the moment of installation. No personal data is sent. Your IP is not kept in the database, the closest we keep is the country code related to the IP submitting the information. This information is used by the Koozali team in order to improve your experience, it can for instance allow us to work more on features needed for a particular country.

To disable the service

 config setprop statusreport status disabled
