Hi everybody! I'm back :)
I'm at the last step! configuring commands.cfg for sending mail notification... in nagios core 4 on ubuntu 12.04
but i'm encountering a problem!
the path for the mail programm (in command .cfg) it's ok! ( i think xD)
but i don't receive any mail notification! :(
and in the nagios.log file there is a strange error...
nagios.log:

In this line:

Code: Select all

[1401457448] wproc:   command: /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: PROBLEM\n\nService: Total Processes\nHost: backups\nAddress: 10.10.2.8\nState: WARNING\n\nDate/Time: Fri May 30 15:43:38 CEST 2014\n\nAdditional Info:\n\nPROCS WARNING: 263 processes\n" | /usr/sbin/sendmail -s "** PROBLEM Service Alert: backups/Total Processes is WARNING **" [email protected]
I don't know why you have "/usr/bin/sendmail" when I would expect it to be "/bin/mail" or maybe "/usr/bin/mail"

Try changing that in your command.cfg (or appropriate Nagios config file) and see if that works. I think you're trying to send mail incorrectly.

Also, you can try sending a test email from the CLI:

Code: Select all

echo "test" | mail -s "test mail"  [email protected]

Hi! and sorry for later answer! :)
when i try to use this command:

Code: Select all

echo "test" | mail -s "test mail"  [email protected]
i got this:

Code: Select all

echo "test" | mail -s "test mail"  [email protected]        
sh: 1: mail: not found
but with this:

Code: Select all

echo "test" | sendmail -s "test mail" [email protected]
i got this:

Code: Select all

WARNING: RunAsUser for MSP ignored, check group ids (egid=1006, want=116)

I have tried to install mail (apt-get install mailutils)
Try changing that in your command.cfg (or appropriate Nagios config file) and see if that works. I think you're trying to send mail incorrectly.
and now i have changed the path in command .cfg in:
# 'notify-host-by-email' command definition

Code: Select all

define command{
        command_name    notify-host-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
        }

# 'notify-service-by-email' command definition
define command{
        command_name    notify-service-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
        }
i have tried to execute this command with nagios user:

Code: Select all

echo "test" | mail -s "test mail"  [email protected]
and the test mail..work!
but unfortunatly no automatically mail notification from nagios yet :(

Any help be appreciate! :)

Can we verify what the full path to mail is

Code: Select all

which mail
also, you would need to make sure you restarted the nagios process after changing the commands ad you had.

Your machine is not set up to properly recognize itself. You need to add your IP address and name to /etc/hosts or a DNS server.

hi eloyd! and thanks for reply!
Your machine is not set up to properly recognize itself. You need to add your IP address and name to /etc/hosts or a DNS server.
in /etc/hosts i have these lines:

Code: Select all

127.0.0.1       localhost
127.0.0.1       backups

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
what i should add?
sorry for my unexperience! :)
