serial notification of contacts by call

[Schimpke, Dr. Thomas / bhn]

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
FS;CRITICAL;notify-by-call;DO IT
[1058538003] Warning: Attempting to execute the command "/usr/sbin/sudo

[1058538003] SERVICE NOTIFICATION: matthias_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 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
FS;CRITICAL;notify-by-call;DO IT
[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
