at the important_application i have to replace it with perl?

i dont have oracle installed. what about the second line i should add?
The article, while targeted at XI, is actually identical for Nagios Core, this article is only touching Nagios Core components.

The article is an "example article" ... it's instructing you how to make the environment variables available to Core when it runs. The values in the article are examples, they are not specific to your problem. You need to work out what varaibles need updating (like the PATH to include the library to the perl module).

What is the exact command you are executing at the command line along with the output?

Show us your command and service definition you created.

That are my definitions:

Code: Select all

define command{
        command_name    check_ups_powerware
        command_line    $USER1$/check_ups_powerware.pl -H $HOSTADDRESS$ -C $ARG$
        }

Code: Select all

define service {
    host_name            10.0.5.112
    service_description        Battery Remaining
    check_command            check_ups_powerware!public!battery_remaining!-U h!$
    max_check_attempts        1000
    check_interval            1
    retry_interval            1
    check_period           24x7
    notification_interval        60
    notification_period       24x7
    contacts            nagiosadmin
}


When i run the command from command line:

Code: Select all

 ./check_ups_powerware.pl -H 10.0.5.112 -C public -T battery_remaining -U h
i get as result this:

Code: Select all

# OK: Battery Remaining: 5.68 Hours|BatteryRemaining=5.68Hours;;;;
but at same time nagios web interface gives me "no output returned from plugin"

We may need to turn on debugging in Nagios, make the problem occur and then review the debug logs.

Try setting the debug level on and then restart Nagios.

Code: Select all

sed -i 's/.*debug_level=.*/debug_level=-1/g' /usr/local/nagios/etc/nagios.cfg
service nagios restart
Make the problem occur (scheduled an immediate check)
Look at the file /usr/local/nagios/var/nagios.debug to find the check being executed.

When you are finished this turns debugging off:

Code: Select all

sed -i 's/.*debug_level=.*/debug_level=0/g' /usr/local/nagios/etc/nagios.cfg
service nagios restart
Does this help?

It looks like the command and the check definition are not correct.
Can you edit the command and change it to the following

Code: Select all

command_line    $USER1$/check_ups_powerware.pl -H $HOSTADDRESS$ -C $ARG1$ -T $ARG2$ $ARG3$ $ARG4$ $ARG5$ $ARG6$ $ARG7$ $ARG8$
Then edit the service check and change that command to this

Code: Select all

check_command           check_ups_powerware!public!battery_remaining!-U m!-w 15!-c 8
Save it and restart nagios.

Then the error should be gone and the check should function for you.

Look at your command definition:

define command{
        command_name    check_ups_powerware
        command_line    $USER1$/check_ups_powerware.pl -H $HOSTADDRESS$ -C $ARG$
        }
$ARG$ needs to be $ARG1$ - having no number is not valid. It also appears that you are passing more args beyond that, but are not using them in the command_line definition. You'll need to fix the command_line for this to work. In particular, you are missing the -U and -T args, so it should be:

Code: Select all

define command{
        command_name    check_ups_powerware
        command_line    $USER1$/check_ups_powerware.pl -H $HOSTADDRESS$ -C $ARG1$ -T $ARG2$ $ARG3$
        }
I am not sure what the extra $ means at the end of the service's check_command but it is likely in error.

Edit: Damn, @tgriep beat me to it :)

This a "copy error". This symbol means that the line does not ends there when you see it at the terminal.

I will try change the definition of the command as you said in a few hours when I will be at office and I will let you know about the result of the change.

I hope this solve the problem.
