Nagios Notificatin by mail

Post by michaelpn »

Hi Nagios,

I have an issue by my mail notification. I do get any mails at the moment still it has worked. I use Nagios Core vers. 4.2.3 on an Linux Ubuntu 14.04. LTS.
I get this from Nagios log when shut down a Server: =>

If I use "wich mail" I do get this => nguser@Nagios:~$ which mail
/usr/bin/mail

1: Could anybody tell me how I'm able to check why it doesn't work ?

2: Is there anybody who could tell me if I missing something in my contacts or commands definitions

3: My send sms do work it is only my mail notification which is not working

As I wrote it did work and I did get the mail notifications from the mail users at Nagios in my Inbox Outlook

I noticed on several of your notification commands you have this

Code: Select all

usr/bin/mail
instead of this

Hi Scottwikerson,

thanks for your answer. You wrote to me that I have "serveral" notification commands with this "usr/bin/mail" I found one in my:

=>
# '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 do only use this cammans right now:

=>

# 'notify-host-by-email' command definition
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 $HOSTSTATE$ **" $CONTACTEMAIL$
}

I have used this shell:

=> tail -50 /var/log/mail.log and got this:

As you see from mail.log it has something to do with Nagios postfix error. What do you propose ?

Do I have to look at some conf files ? and if where ?

Re: Nagios Notificatin by mail

It looks like it is failing to resolve the MX record for the email ending in fgmail3.fg.dk

Does this host exist?

Also, your from address is nagios@Nagios.notify and you should be aware that some mail providers will reject mail if the from address cannot be resolved as well.

Your nagios server doesn't know how to resolve the MX

do you have the right DNS server

cat /etc/resolv.conf

Hi scottwilkerson,

if use that shell I get this:

=>

nguser@Nagios:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
search fg.dk

That is a localhost address and our nameserver (NS) has this address ad1.fg.dk.

If I use this shell:
=>

cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
search fg.dk



And my main.cf looks like this:
=>

# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default

I have a strong filing that have to change the nameserver IP 127.0.1.1 to ad1.fg.dk

Please look below:

Ikke-autoritativt svar:
domain.com MX preference = 10, mail exchanger = mx.domain.com

mx.domain.com internet address = 66.96.140.73
mx.domain.com internet address = 66.96.140.72

C:\Users\mpn.FG>nslookup -type=mx fgmail3.fg.dk

Address: 172.31.1.221

fg.dk
primary name server = ad1.fg.dk
responsible mail addr = itafd
serial = 34121
refresh = 900 (15 mins)
retry = 600 (10 mins)
expire = 86400 (1 day)
default TTL = 3600 (1 hour)



What do you think ?

How do I change ?

You need to know the IP address of ad1.fg.dk, and replace XXX.XXX.XXX.XXX with that address

Edit /etc/resolvconf/resolv.conf.d/base

Code: Select all

nameserver XXX.XXX.XXX.XXX
Then run

Code: Select all

sudo resolvconf -u

Hi scottwilkersson,

thanks :)

If I have to edit the file "base"

I have to use root command to change the file base:

I use vi command => vi /etc/resolvconf/resolv.conf.d/base

If look into the base file I see it is emty!! I think as you wrote to me I have to edit this file so:

put the ip-adrress into the as below written:
=>
nameserver xxx.xxx.x.xx

save the base file and run the command:
=>
sudo resolvconf -u

Is that correct ?
