Perl plugins: No output from plugin

When you ran it by hand as nagios user, did you include all relevant
arguments?
/opt/nagios/plugins/check_snmp_load.pl -H x.x.x.x -C public -w 2,2,3 -c
3,3,4 -L
Another trick to verify that you're running it by hand correctly is to
do
define command{
command_name check_linux_load
command_line echo $USER1$/check_snmp_load.pl -H $HOSTADDRESS$
-C public -w $ARG1$ -c $ARG2$ -L
}
The command will appear in the UI, and then you can run what is shown.
"No output from plugin" means just that. Nagios is expecting some kind
of statement about the check. Your check is not outputting anything.
You're getting a difference between running by hand and running
automatically. Get those to be the same, it'll be easier to track down.

Subject: [Nagios-users] Perl plugins: No output from plugin
I'm trying to use the check_snmp_load.pl and check_snmp_storage.pl
I can run the plugin from the command line (as both root and nagios
user) and get the right results but when it's fired off automatically I
keep getting "No output from plugin".
Here are the relevant config:
define service{
use generic-service
hostgroup_name LinuxServers
service_description LOAD
is_volatile 0
check_period 24x7
max_check_attempts 3
normal_check_interval 5
retry_check_interval 1
contact_groups domain-admins
check_command check_linux_load!2,2,3!3,3,4
}
define command{
command_name check_linux_load
command_line $USER1$/check_snmp_load.pl -H $HOSTADDRESS$ -C
public -w $ARG1$ -c $ARG2$ -L
}
$USER1$=/opt/nagios/plugins
[root at cartier plugins]# ls -l /opt/nagios/plugins/check_snmp_load.pl
-rwxr-xr-x 1 root root 14168 Aug 22 12:42
/opt/nagios/plugins/check_snmp_load.pl
Thanks,
