How to send notificatiosn from Nagios through Exchnange server on same network

AST · 10-24-2011, 10:57 AM

Hello all,

Please bear with me, i am sooooo new to Linux (as of 5 hours ago)
Newer to Nagios (as of 3 hours ago)

The company systems admin had started last week to install nagios on an Ubuntu box (desktop version i believe)

However he decided that over the weekend he wasnt coming back to work!

So now i have been tasked with continuing the nagios install.

It appears nagios is installed and a wireless router is being monitored.

My question is this - i dont know a fat lot about Microsoft Exchange Server but my boss tells me i ultimately need to get our switches monitored and email alerts sent from nagios through the exchange server to my email address.

I have installed postfix and mailx and set up a satellite option.

Now i need to edit the main.cf but im not sure what i put in it.

A bit of info for you:

My network is a 192.168.1.x network and uses a 255.255.255.0 subnet

My domain name is MYTOWN.MYCOMPANY.CO.UK

My linux box is called BFCNAGIOS

My Exchange Server is called BFCMAIL and has an IP of 192.168.1.60

My Exchnage Server Full Computer Name is BFCMAIL.MYTOWN.MYCOMPANY.CO.UK

My email address doesnt have the MYTOWN in though and is just MYEMAIL@MYCOMPANY.CO.UK

I have created a recieve connector for the Nagios machines IP address on my Exchange Server to allow mail from it to relay thorugh.

So should my main.cf file look like this?

myhostname = BFCNAGIOS
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = MYCOMPANY.CO.UK, MYTOWN.MYCOMPANY.CO.UK
relayhost = 192.168.1.60
mynetworks = 192.168.1.0/24
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

All i want is for Nagios to send the alerts to the local Exchange server and then the Exchnage server to send them to me!

Will this do the job or have i configured incorrectly?

Thankyou so much in advance for any help given.

You have 3 options:
1. Make the exchange server relay mail for the nagios server and configure postfix to use the exchange server for sending mail.

2. Create a mail account on the exchange server that will redirect all mail to your external email. Configure nagios to send the emails to the email account from the exchange server

3. Set up a mail account on the exchange server and make nagios send using smtp authentication with the mailx command against that mail account. Check this link for how to make mailx do that: http://heirloom.sourceforge.net/mailx/mailx.1.html

Let me know which option you want to choose and we'll go into the details

Id like number 1 vasile002.
I want the nagios machine to send the mail to the local exchange server and for the local exchnage server to do all the sending to me.

Thankyou

Here's how you can add a relay into your exchange server:

For postfix you need to set this option in main.cf:
relayhost = EXCHANGESERVER

Let me know if you still have problems

Just to throw something out there.... have a think about looking at FAN - Fully Automated Nagios, it's well worth a look at if you want to integrate a few nice tools.
