[SOLVED] Rsyslog and CRON disable

[lixaotec]

Dear folks,

I´ve been trying to stop CRON tasks from being log at syslog in my pve 6.2 host, however nothing seems to works.

i´ve changed /etc/rsyslog.conf to:

#
# First some standard log files. Log by facility.
#
auth,authpriv.* /var/log/auth.log
*.*;auth,authpriv.none,cron.none -/var/log/syslog
cron.* /var/log/cron.log
daemon.* -/var/log/daemon.log
kern.* -/var/log/kern.log
lpr.* -/var/log/lpr.log
mail.* -/var/log/mail.log
user.* -/var/log/user.log

After then I restarted rsyslog service
service rsyslog restart

And nothing seem to happen, I see log of rsyslog restart, but the CRON (that runs every minute) keep login its pam_unix lines

What is missing?

Thanks

hi,

change

*.*;auth,authpriv.none,cron.none -/var/log/syslog

to

*.*;cron,auth,authpriv.none     -/var/log/syslog

and restart the rsyslog service again

Dear @oguz ,

Thanks for replying.

I did it, but it is still loggin Cron pam_unix messages at syslog,

Ive tried a bunch of combination. I have a job running every minute, and it is very annoying to have 3 new messages at syslog everytime.

if there is another trick please, let me know.

I figured out something, perhaps its the issue' .

In fact it seems that /var/log/syslog didnt show cron logs, however proxmox gui Syslog menu it seems to show them,

Is it something that shows all logs merged?

thanks

If syslog menu shows all /var/log/ files merged, is it possoble to supress some of them like cron.log?

 

[lixaotec]

In a brief proxmox research Ive verified that Syslog feature reads from 'journal' that goes up to the tool proxmox-mini-journalreader

It seems that it does not read from the filtered written logs, maybe @Dominic may provide some information to clarify this behaviour?

Thank you so much

Just to note, Proxmox uses journal service, that hasnt yet any way to do a filtering. https://github.com/systemd/systemd/issues/6432

Peharps a grep filter at Proxmox tool (proxmox-mini-journalreader.git) should accomplish well a GUI filtering in order to avoid spam from crons and other that rsyslog filters.
