[Solved] Install won't relay off of my Exchange 2007 server

jbruyet · Post by **jbruyet** » Wed Nov 20, 2013 6:59 pm

Hey all, I had a simple Nagios server running on CentOS and decided to move it over to my FreeBSD 9.1 server. it's running great so now I'm working on notifications and I'm not making any progress. I am able to send an email to myself from the command line so my Exchange server is allowing my Nagios to relay off of it, when I check the maillog I see a bunch of "stat=Sent" lines so I'm pretty sure that the emails are leaving the Nagios server but I'm not seeing anything from it in my Exchange queue. I read several articles that said I needed to install sendEmail so I did that but I can't see where I direct traffic to my Exchange server so I'll get the emails. I'm not sure what my next steps should be so here I am. Does anyone know where I can find a tutorial that will help me get my Nagios alerts sent to me as emails?

Thanks,

Joe B

Can you choose one host > service definition to test with and share your host, and service configuration definitions for them as well as the templates that may or may not be assigned? We'd like to take a look at the notification commands that are being used.

Sorry for the slow reply; we're getting a new radio system and that's been my priority. Then I somehow wiped out a bunch of my files. Sigh, everything is backed up now.

Ok, it's a bit long but here goes...

Could you also post the notify-host-by-email definition, just so we have a complete picture. Along the same lines, most times that command will use the local mta and if it is not configured to send externally, the mail may be spooling in the local mail queue\spool.

jbruyet · Post by **jbruyet** » Mon Dec 02, 2013 5:55 pm

Here's my configuration:

Code: Select all

# '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/local/bin/sendEmail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
    }

I read in a few places that the sendEmail program was one of the better ones to use.

You know, now that I think about it I don't believe I ever configured the sendEmail program to send emails to my Exchange Server. I'll have to check in to that...

Thanks,

Joe B

Oh, the SMTP server is specified when the email is sent.

Thanks,

That last post was a bit cryptic, did you get this working?

jbruyet · Post by **jbruyet** » Wed Dec 04, 2013 7:56 pm

As I understand it the sendEmail program is more of a command line email program for use in scripts so the Exchange server address needs to be added to the script.

I'm still working on this and I'm starting to think I should get rid of the sendEmail program and use the default FreeBSD mail transport agent. Seems like I had this working in a previous install...

Thanks,

I agree. mailx supports sending through an smtp relay, and I am sure other vanilla bsd clients do as well. You just need to hunt down the right syntax for sending to an smtp relay for the client of your choice.

Ok, I've removed sendEmail from my Nagios server and from what I can find on Google I believe I have my alerting configuration set correctly (I've made a few tweaks because just about everything I've seen is for Linux and FreeBSD does things a little differently). I created a test configuration for a computer and it shows up as a critical state in Nagios but I'm still not getting notifications. I checked my spam filter to see if my notifications were getting blocked but there aren't any notifications there. I'm using the information from these two web sites to configure my notifications:

http://www.thegeekstuff.com/2009/06/4-s ... ification/

http://www.linux.com/learn/tutorials/31 ... ith-nagios

Do either of these two sets of instructions not translate into FreeBSD terminology? Is there a FreeBSD page with instructions on how to configure alerting?

Thanks,

Joe B
