The following includes are required:

use Getopt::Long;
use Mail::Sendmail;
use Digest::MD5 qw(md5_hex);
use MIME::Base64;
use File::Temp;

At the moment, we know you need Mail::Sendmail:

Code: Select all

yum install perl-Mail-Sendmail

That's the one I missed:

Code: Select all

yum install perl-Mail-Sendmail

I put one in downtime, and I see this:

Code: Select all

[1385068727] wproc:   early_timeout=0; exited_ok=1; wait_status=512; error_code=0;

and

Code: Select all

[1385068794] wproc:   stderr line 01: Can't locate RRDs.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at /usr/local/nagios/bin/nagios_send_service_mail.pl line 38.

How about:

Code: Select all

yum install rrdtool rrdtool-devel rrdtool-perl

You may also need:

Code: Select all

yum install perl-RRD-Simple

Posted: **Thu Nov 21, 2013 5:15 pm**

[root@vmmgmtappnagios var]# yum install perl-RRD-Simple
Loaded plugins: security
Setting up Install Process
No package perl-RRD-Simple available.
Nothing to do
[root@vmmgmtappnagios var]#

the rest worked fine though.

and now getting:

[1385072067] wproc: command: /usr/local/nagios/bin/nagios_send_host_mail.pl -c "" -f html -u

It looks like the first script (/usr/local/nagios/bin/nagios_mail.php) is not handing off any of the macro values to the second script (/usr/local/nagios/bin/nagios_send_host_mail.pl).
Did you ever verify if the first script was able to use the env vars?

Posted: **Thu Nov 21, 2013 11:53 pm**

Is there a simple way to verify that?

Posted: **Fri Nov 22, 2013 10:41 am**

You could add some debug output to the first file to check if it is getting the env vars. As it is php, I would suggest using "put_file_contents" (http://us2.php.net/file_put_contents).
Have it dump some of the php vars that were loaded from the env vars to a file in /tmp.

Where would I add that exactly?

Posted: **Mon Nov 25, 2013 1:04 pm**

okay, so I am going to skip that mail script and go back to the old one, as the format looks better. To start debugging it ... I was able to send a test email no problem generated by the script, but it seems like nagios cannot send any on its own.

I see one message in my /var/log/maillog and it was the only successful attempt that I sent via my test command line. I don't see any errors in nagios.log when the script is trying to execute...so I am not sure what other log files I can look at to narrow down where the problem is.

Can you post the command definition that is configured for this script please? Does this have read and execute permission for the nagios user and group? Where is it located on your file system? Can you su to the nagios user and execute by hand or does that also give an issue?
