How can I get journal logs in a systemd --user OnFailure unit (journalctl not working)
Systemd provides the OnFailure= mechanism for invoking actions upon failure. The most obvious use for this is to act like cron's MAILTO= and email logs when a unit fails. I tried that under Ubuntu 16.04 with this approach in a .service unit that gets started by OnFailure=
ExecStart=/bin/sh -c 'journalctl --user-unit=<my unit> -n 20 | mail -s "Unit failed" <my email address>'
This gets no output from journalctl. The exact same command, starting from /bin/sh, functions perfectly when executed from the shell prompt.
I've filed this as a bug on Ubuntu (https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1810351), but if I'm to use the systemd features that replace cron, inotify, inetd, etc. then I must have basic error reporting and I cannot wait for the bug fix. Does anyone know of a workaround for this fundamental flaw in journalctl/systemd?
