Well, then the script is being called but doesn't output anything. Is
that normal? It's looking more and more to me that you need to get more
verbose output from the 'client' program. Everything we've done so far
indicates that nagios is doing exactly what it's supposed to.

Well, it should be working. Stepping through the process --
1) nagios is running the notification command as necessary
2) the notification command is properly formatted (seen by echo
output)
3) the notification command succeeds when run as the nagios user
from the command line
That really should be sufficient. The only other issue I can think of is
that your pager program relies on some program, path, environment
variable or library that is available when in a login shell but
unavailable to forked processes. Do you set any special variables,
aliases or anything in your login scripts? Can the people that wrote it
provide any insight or add debugging code to the program?
Try this to see if the program is reporting any errors --
# 'notify-by-pager' command definition
define command{
command_namenotify-by-pager
command_line/usr/local/pager/client $CONTACTADDRESS1$
"Service: $SERVICEDESC$\nHost: $HOSTNAME$\nAddress:
$HOSTADDRESS$\nState: $SERVICESTATE$\nInfo: $SERVICEOUTPUT$\nDate:
$LONGDATETIME$ $NOTIFICATIONTYPE$: $HOSTALIAS$/$SERVICEDESC$ is
$SERVICESTATE$"'>> /tmp/nagios_notification.log 2>&1

It is an application written in-house in C, I don't have any visibility into it but it basically just sends a message to its server component that then dials out to the paging company and sends the message.

These look fine (probably). Is 'client' a script or program that you
wrote or have visibility into? What does it do exactly.

That's a good start. Did you run your test as the nagios user? Perhaps
your client script accesses some script/program/device that only root
has permissions to use.

Shell Scripting 101: quoting as above is nulls your quotes. You open a "
then immediately close it leaving the rest to be interpreted as
arguments to the echo command. Plus, you want the echo to be the entire
command. What you want for this testing is --
# 'notify-by-pager' command definition
define command{
command_namenotify-by-pager
command_lineecho '/usr/local/pager/client $CONTACTADDRESS1$
"Service: $SERVICEDESC$\nHost: $HOSTNAME$\nAddress:
$HOSTADDRESS$\nState: $SERVICESTATE$\nInfo: $SERVICEOUTPUT$\nDate:
$LONGDATETIME$ $NOTIFICATIONTYPE$: $HOSTALIAS$/$SERVICEDESC$ is
$SERVICESTATE$"' >> /tmp/nagios_notification.log
}

Hi,
You should be able to backslash the quotes you need it to print:
$ echo "\"hi\""
I'm not sure where above you would want them, maybe something like
\"$SOMEMACRO$\" \"$SOMEOTHERMACRO$\" ?

I'm not sure what you mean. Post what you ended up with. Were they lost
because I used double-quotes and you use double-quotes? If so, change
mine to single-quotes.

Nope. If you're using valid nagios $MACROS$ then nagios will do the all
the substitutions before the echo is even called so you should see the
actual full command line exactly as it is run.

Doing what you suggest I see that it IS running the notification,
except that the quotation marks are lost (which my external app
actually needs - so maybe I can double them up?) and none of the
variables have been filled in within the quotes that are there
(perhaps because it was an echo, and the echo command wiill take
anything with quotes as strings?).

Make sure you have log_notifications=1 in nagios.cfg. Then you'll be
able to see in nagios.log whether your notification is being called. If
it is not then it's a simple configuration issue (notifications not
enabled globally, not enabled specifically for that host or service or
for that specific contact).
If the notification is being called but you don't see what you expect in
your notification script, echo the command that nagios is running to a
file to see if it's what you think it's supposed to be --
define command {
command_name my_special_notification
command_line echo "$USER1$/my-notification-script
$SOMEMACRO$ $SOMEOTHERMACRO$" >> /tmp/nagios-runs-me
}
After nagios calls 'my_special_notification', the file
/tmp/nagios-runs-me will contain the full command line that nagios
_would_ have executed if it had really run the command.
If the notification is being called, modify your notification script to
output interesting information to a log file. In all my event handlers
the first thing it does is log the parameters it was called with ala --
LOGFILE=/usr/local/nagios/var/eventhandler.log; export LOGFILE
echo -n `date` . " " >> $LOGFILE 2>&1
echo "winbind service check ($1) ($2) ($3) ($4)... " >> $LOGFILE 2>&1
Whenever there's something interesting happening, I log that --
echo -n `date` . " " >> $LOGFILE 2>&1
echo -n "Restarting winbind service (2nd soft critical state) on $4... "
>> $LOGFILE 2>&1
# Call the init script to restart the winbind server
/usr/bin/ssh $4 'sudo /etc/init.d/winbind restart' >>$LOGFILE 2>&1
I also log if I don't do anything. I log errors from the scripts that I
call from my event handler or anything else that might be interesting. I
presume there's no reason you couldn't do this in your expanded
notification script and you have no real limitations on how verbose you
make the process.

[Nagios-users] external notification commands
I have a notification configured to run an app and pass it Nagios parameters. For what ever reason I can watch the log and see a device go critical, but it never runs the notification command, or, if it does, it doesn't work.
