How to list the queued units with systemctl

systemd

My systemctl status shows:

● mymachine
     State: running
     Jobs: 4 queued

How can I list the queued jobs?

This answer shows how to list the failed units, but I can't find any docs on how to list those 4 queued units, nor is it clear to me which state in systemctl list-units --state=help corresponds to those.

It is: systemctl list-jobs

Example output:

# systemctl list-jobs
 JOB UNIT                                  TYPE  STATE  
3543 nginxAfterGlusterfs.service           start waiting
3545 glusterReadyForLocalhostMount.service start running
3506 nginx.service                         start waiting

4 jobs listed.

Those units also have a start entry in the JOB column in the systemctl table.

List of selectable units for journalctl

journalctl can display logs for all units - whether these units write to the log is a different matter.

To list all available units and therefore all available for journalctl to use:

systemctl list-unit-files --all

As to your java code, in order to make pipes work with Runtime.exec() you could either put the command in a script and invoke the script or use a string array, something like:

String[] cmd = {"sh", "-c", "command1 | command2 | command3"};
p = Runtime.getRuntime().exec(cmd);

or:

Runtime.getRuntime().exec(new String[]{"sh", "-c", "command1 | command2 | command3"});

Systemctl remove unit from failed list

Use systemctl to remove the failed status. To reset all units with failed status:

systemctl reset-failed

or just your specific unit:

systemctl reset-failed openvpn-server@intranert.service
