Nagios not sending e-mail notification

[homerkaro]

Hi!
This is the first time I'm setting up Nagios but i can't get notifications working.
I get the following error in nagios log:
[Mon Aug 25 13:28:47 2014] SERVICE NOTIFICATION: nagiosadmin;srv0102vg;C:\ Drive Space;WARNING;notify-service-by-email;c:\ - total: 464,63 Gb - used: 385,00 Gb (83%) - free 79,63 Gb (17%)

[Mon Aug 25 13:28:47 2014] wproc: stderr line 02: /usr/bin/printf: íráshiba: Broken pipe

What is wrong?
Thanks!

Can you run the following commands and show us the output?

Code: Select all

ls -l /usr/sbin/sendmail
ls -l /var/spool

I also have this problem.

homerkaro, Mapienator,

What distributions are you using?

Code: Select all

cat /etc/*release
uname -a

[Mon Aug 25 15:24:31 2014] wproc: stdout line 02: can not chdir(/var/spool/mqueue-client/): Permission denied

You are right in thinking that this is likely a permission error. Do you have selinux/apparmor on?

Let's take a look at your users and groups, respectively:

Code: Select all

cat /etc/passwd
cat /etc/group

Which user is sendmail running as?

I Found my problem already. Te home dir and the permissions on the Nagios user where corrupt for some reason. I just corrected that and rebooted the system. Works like a charm.

Still thanks!

No problem.

homerkaro, let us know if you are still having troubles. Thanks!
