Nagios 3.5.0 problem with macro $ADMINEMAIL$

Hello,
We just update to Nagios 3.5.0 on our nagios server and we have a problem with $ADMINEMAIL$ macro in notification.
We have a charset problem with the value passed to our notification commands.
In nagios.cfg file :
The value of $ADMINEMAIL$ in our notification process :
The
@ character is transorm in
%40
The changelog of Nagios 3.5.0 :
This release contains bug fixes and updates related to downtimes, restarts, and to the way non-ASCII characters are handled
Do someone else had the same problem since Nagios 3.5.0 ? Is this a bug in the new version ? Where can we see this charset translation in source code ?
Thank you !

This is curious. I emailed a link to one of our core devs, if he does not get back to me by Friday, I will see him in person. Sit tight.

We see that if we do a Nagios restart, the problem disappeared. But when we do a Nagios Reload, the problem is back again.

Hello,
I work with Jimmy (author of the topic), and I work on this problem too.
For French speaker, I made more debug here :
http://forums.monitoring-fr.org/index.php?topic=6612
I will try to explain everything here :
The problem occurs after a second reload of Nagios.
Here is the notification command :
Code: Select all
define command{
command_name notification_service_par_mail
command_line $USER1$/sendmailservices.sh "$CONTACTEMAIL$" "$ADMINEMAIL$"
}
Here is my notification script (for test) :
Code: Select all
#!/bin/bash
TO=$1
EMETTEUR=$2
echo "$TO $EMETTEUR" >> /tmp/notifBash.log
1- I restart Nagios and force a notification, everything works fine :
2- I reload Nagios and force a notification, everything works fine :
3- I reload Nagios again and force a notification, problem occurs :
--- Another test, if my script sendmailservices.sh is not executable :
1- I restart Nagios and force a notification, here is the nagios warning :
[1366287128] Warning: Attempting to execute the command "/usr/local/nagios/libexec/sendmailservices.sh "
[email protected]" "
[email protected]"" resulted in a return code of 126. Make sure the script or binary you are trying to execute actually exists...
2- I reload Nagios and force a notification, here is the nagios warning :
[1366287189] Warning: Attempting to execute the command "/usr/local/nagios/libexec/sendmailservices.sh "
[email protected]" "
[email protected]"" resulted in a return code of 126. Make sure the script or binary you are trying to execute actually exists...
3- I reload Nagios again and force a notification, here is the nagios warning :
[1366287254] Warning: Attempting to execute the command "/usr/local/nagios/libexec/sendmailservices.sh "
[email protected]" "user%40domain.fr"" resulted in a return code of 126. Make sure the script or binary you are trying to execute actually exists...
My conclusion : after a second reload, nagios converts the '@' in the 'ADMINEMAIL' macro...

Make sure that you do not have orphans or hung copies of the nagios process on reload.
Code: Select all
service nagios stop
killall nagios
Verify they are gone:
If so, restart:

Hello,
Well, everything works fine when I restart nagios ( nagios restart / nagios stop && nagios start / killall nagios && nagios start )
It's after the second reload that the bug seems to appear.
Edit : I opened an issue in the bugtracker

When you are stopping Nagios is it going down cleanly or giving an error that it didn't stop in a timely manner?

Hello,
Nagios is going down cleanly when I stop it.

If you stop nagios and kill any orphans, wait a moment, and then start nagios, is this reproducible every time?

Hi,
Here is how I reproduce the bug :
1 - /etc/init.d/nagios stop
2 - kill any nagios processes left / any orphan / etc... --> killall nagios + kill -9 <pid>
3 - /etc/init.d/nagios start
--> bug not present
4 - /etc/init.d/nagios reload
--> bug not present
5 - /etc/init.d/nagios reload
--> bug present
