In general, we no longer use tmpwatch at all. In CentOS 7 and 8, use systemd-tmpfiles. Here is a blog post that describes it pretty well:
https://developers.redhat.com/blog/2016/09/20/managing-temporary-files-with-systemd-tmpfiles-on-rhel7/
Thanks, it seems that this migration will take more time :-).
Okay, systemd-tmpfiles is a reasonable solution for one scenario
here but some questions still persists for a second one:
As you see - the next clean up will be in 23h
# systemctl status systemd-tmpfiles-clean.timer
● systemd-tmpfiles-clean.timer - Daily Cleanup of Temporary Directories
Loaded: loaded
(/usr/lib/systemd/system/systemd-tmpfiles-clean.timer; static; vendor
preset: disabled)

Trigger: Sun 2020-08-30 22:07:52 CEST; 23h left
Docs: man:tmpfiles.d(5)
man:systemd-tmpfiles(8)
# systemctl list-timers
NEXT LEFT LAST
PASSED UNIT ACTIVATES

39min ago systemd-tmpfiles-clean.timer systemd-tmpfiles-clean.service
What triggers cleanups that must be done every hour for example?
# cat /usr/lib/tmpfiles.d/app-tmp.conf
e /srv/app/*/tmp - - - 1h
# man tmpfiles.d
is mentioning (m)minutes, (s)econds and even us (microseconds).
Do I need to override the systemd-tmpfiles-clean.timer unit?
# systemctl cat systemd-tmpfiles-clean.timer
...
[Timer]
OnBootSec=15min
OnUnitActiveSec=1d
It seems that this is more prepared for daily clean ups?
