[Nagiosplug-help] Issues with Remote Event Handling via NRPE

[Garrett Honeycutt]

I am attempting to run an event-handler via nrpe. I wrote a quick test
script
------------------------------------------------
test.sh
#!/bin/bash
wall "arg1 is $1 :: arg2 is $2 :: arg3 is $3"
exit 0
-----------------------------------------------

When I run 'check_nrpe -H janis -c test -a CRITICAL HARD 3' I get "NRPE:
Unable to read output" on the server and the expected results on the
client.

----------------------------------------------------------
Broadcast message from nagios (Fri Sep 16 14:09:01 2005):

arg1 is CRITICAL :: arg2 is HARD :: arg3 is 3
----------------------------------------------------------

When I run 'check_nrpe -H janis -c restart-apache -a CRITICAL HARD 3' I
get "CHECK_NRPE: Error receiving data from daemon." and nothing happens
on the client. 

When su nagios on the client and run the script by
hand, ./restart-apache CRITICAL HARD 3, It works great and restarts
apache. 

Where am I going wrong? I appreciate your help and have included all the
pertinent data below.

Thanks

[ nrpe was rebuilt as follows ]


./configure --with-nrpe-user=nagios --with-nrpe-group=nagios
--with-nrpe-port=5666 --enable-ssl --enable-command-args

I copied the src/check_nrpe to my libexec directory and I scp'd src/nrpe
to janis:/usr/sbin/

[ misccommands.cfg ]

define command{
    command_name    restart-apache
    command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c
restart-apache -a $SERVICESTATE$ $STATETYPE$ $SERVICEATTEMPT$
}

[ services.cfg ]

define service {
use		      generic-service
host_name             janis
service_description   apache process
// if there are 0 httpd processes, we have a problem
check_command         check_nrpe!check_apache_proc
event_handler         restart-apache
is_volatile           0
max_check_attempts    3
normal_check_interval 5

notification_interval 60
notification_period   24x7
notification_options  w,c,r
contact_groups        group
}

generic-service DOES have  
event_handler_enabled       1

[ hosts.cfg ] 

generic-host also has
event_handler_enabled       1

[ nagios.cfg ]

log_event_handlers=1
event_handler_timeout=30
enable_event_handlers=1


----------------------------------------------------

[ nrpe.cfg on client contains ]

dont_blame_nrpe=1

command[restart-apache]=/home/nagios/events/restart-apache.sh $ARG1$
$ARG2$ $ARG3$
