Systemd systemctl list all failed units/services on Linux

Author: Vivek Gite Last updated: April 20, 2020 0 comments

Is there is a command to print list all failed units or services when using systemd on Linux? Can you tell me the systemctl command to list all failed services on Linux?

This quick tutorial explains how to find/list all failed systemd services/units on Linux operating systems using the systemctl command.

Systemd systemctl list all failed units/services command

The systemctl command used to control the systemd system and service management. To list units that systemd currently has in memory, pass the list-units argument to the systemctl as follows on Linux:
sudo systemctl list-units --failed ## OR ## sudo systemctl list-units --state failed

Linux systemctl list all failed units or services command

The systemctl command options to list all failed units/services

A note about the is-failed option

We can check whether any of the specified units or services are in a “failed” state under Linux. The following command returns an exit code 0 if at least one has failed, non-zero otherwise. Unless the --quiet option passed to the systemctl command, this will also print the current unit state to standard output. So, if you know the service or unit name try the following command:
sudo systemctl is-failed {service-name-here} sudo systemctl is-failed nginx.service sudo systemctl is-failed vboxweb.service
Another option is to run the following simple command along with the grep command to list failed services with systemctl:
sudo systemctl list-units | grep -i failed

How to find status of systemd unit or service

Pass the status option as follows:
sudo systemctl status {service-name} sudo systemctl status ssh.service sudo systemctl status nginx.service sudo systemctl status vboxweb.service

Show properties of a service unit

Run the following command:
sudo systemctl show {service-name} sudo systemctl show vboxweb.service

How to view log messages

Log messages can provide in-depth information about services that we can use to debug issues. The syntax is as follows:

Display all messages

journalctl journalctl | grep 'error'

Show only kernel messages

journalctl -k

View live messages on screen as they appear

journalctl -f

How to view service specific messages only

journalctl -u {service-name-here} journalctl -u ssh.service journalctl -u vboxweb.service

We can now search for those errors online or read man pages to sort it out.

Conclusion

We learned how to show services/units that failed to run on Linux using the systemctl command. See systemctl man page here for more info.
