Tripp Lite Check_PDU plugin

[hillhealthcenter]

I'm trying to use the Check_PDU plugin for Tripp Lite PDUs from the Exchange. However, I'm getting this error:

Code: Select all

(No output on stdout) stderr: Can't locate utils.pm in @INC (@INC contains: /usr/local/libexec/nagios /usr/local/lib/perl5 /usr/local/share/perl5 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5 /usr/share/perl5 .) at /usr/local/nagi
BEGIN failed--compilation aborted at /usr/local/nagios/libexec/check_pdu line 7

It looks like it's sourcing /usr/local/libexec/nagios and not /usr/local/nagios/libexec - you should be able to update the plugin to include that path and get things working properly.

Code: Select all

[root@centos7 etc]# locate utils.pm
/usr/local/nagios/libexec/utils.pm
/usr/local/nrdp/plugins/AIX/utils.pm
/usr/local/nrdp/plugins/Generic/utils.pm
/usr/local/nrdp/plugins/SunOS/utils.pm

Thanks for getting back to me so quickly. Now I'm getting this error:

Code: Select all

(Return code of 255 is out of bounds)

What are the permissions on it? ls -la /usr/local/nagios/libexec/check_pdu

My guess is they're set to root:root, and you'll just want to adjust it accordingly. (generally apache:nagios)

[hillhealthcenter]

Here's output:

Code: Select all

/usr/local/nagios/libexec$  ls -la /usr/local/nagios/libexec/check_pdu
-rwxr-xr-x 1 apache nagios

Are you able to run it manually from the CLI?

Please post the command + service definition you're using to monitor with.

[hillhealthcenter]

I get this error from the CLI:

Code: Select all

/usr/local/nagios/libexec$ ./check_pdu -h 192.168.90.72 tripplite inputv 105 118
Can't call method "getnext" on an undefined value at ./check_pdu line 45.

Here are the command and service configs:

Code: Select all

define command {
       command_name                  		check_pdu
       command_line                  		$USER1$/check_pdu -H $HOSTADDRESS$ $ARG1$ $ARG2$ $ARG3$ $ARG4$
}

Noticing this in the usage -

Code: Select all

my $usage = '
Usage: ${0} hostname snmp_community key min max

I don't think you need the -h in there as it's messing up where the IP should be.

The other part is in the header -

Code: Select all

use SNMP; # requires net-mgmt/p5-Net-SNMP

Do you have that package installed?

[hillhealthcenter]

I'm not sure if I have that particular package installed. How do I check? I'm already using SNMP to monitor APC UPS devices in our network, if that helps.

[rkennedy]

After reviewing https://secure-computing.net/wiki/index.php/PDU_Nagios - I believe net-snmp on CentOS should cover it.

Are you still seeing the same error after altering your check command to remove the -h, or what is the result now?
