serial notification of contacts by call

[Mark Musone]

A quick fix is to have nagios send email to a "callout" userid..

Then procmail or whatever mail filter you want to parse and vboxputty
Out..

The wonderful thing about mail programs is that they handle queueing and
serialization automagically..

You can even re-queue it if the phone is busy or fails for some reason!

Hope to help,
Mark

Subject: [Nagios-users] serial notification of contacts by call

Hi all,

I'd like to set up nagios, so that each member of a contactgroup gets a
call
on his mobile phone. I use vboxputty to do the work, which works OK. The
problem seems to be, that nagios tries to call all members of that
contact
group at the same time. From the nagios log file:


[1058538003] SERVICE NOTIFICATION: thomas_call_work;eulep01;P01/saparch
FS;CRITICAL;notify-by-call;DO IT
[1058538003] Warning: Attempting to execute the command "/usr/sbin/sudo
/usr/sbin/vboxputty -r 40 -t 40 -d /dev/ttyI0 -c 215xxx
[1058538003] SERVICE NOTIFICATION: rz_call_work;eulep01;P01/saparch

[1058538003] Warning: Attempting to execute the command "/usr/sbin/sudo
/usr/sbin/vboxputty -r 40 -t 40 -d /dev/ttyI0 -c 126xxx
[1058538003] SERVICE NOTIFICATION: thomas_call_home;eulep01;P01/saparch
FS;CRITICAL;direct-call-service;DO IT
[1058538033] SERVICE NOTIFICATION: holger_call_home;eulep01;P01/saparch

[1058538034] Warning: Attempting to execute the command "/usr/sbin/sudo
/usr/sbin/vboxputty -r 40 -t 40 -d /dev/ttyI0 -c 001xxxxxxx

etc.

I took a look at the source code and found, that for a notification
my_system() is called, which essentially forks() and executes the
command
(vboxgetty in this case). vboxgetty does not wait (to my knowledge), if
the
originator line is busy, but returns emmidiately with an error. So only
one
contact of the contactgroup gets notified.

Is there a way to tweak nagios so, that each contact is notified in turn
?
Things look bad..I know...

Thanks in advance,

Thomas
