ZEVENET Monitoring not returning Data

[tgriep]

Most of the messages were warnings telling you that to install that package, you need to install other packages first.
Go through the list, install those first and then continue on.

I was asked to install "perl -MCPAN -e 'install Monitoring::Plugin' "
but i don't think is necessary due the VM is the one Nagios provide. could you please confirm if not necessary?

It may be required for some plugins. Our VM has the package Nagios::Monitoring::Plugin installed by default, but if a plugin author uses Monitoring::Plugin you would either need the package or need to modify the plugin to use Nagios::Monitoring::Plugin

great, so it would not "harm" the actual monitoring, right?

[npolovenko]

@lpereira, Nope, I don't see how it could harm Nagios. You can always uninstall it if you'd like.

I have installed the package YAML but still having issues with the output

One fix I found after searching, try changing this line from

Code: Select all

$retcode = $curl->perform;

to

Code: Select all

my $retcode = $curl->perform;

and see if it fixes the issue.

This is what i have on the plugin

Code: Select all

#  ZAPI v3 call
my $response_body;
my $retcode;
my $response_code;
my $response_decoded;
my $curl = WWW::Curl::Easy->new;
$curl->setopt(CURLOPT_HEADER,0);
$curl->setopt(CURLOPT_SSL_VERIFYPEER, 0);
$curl->setopt(CURLOPT_SSL_VERIFYHOST, 0);

# Maximun time that a given cURL operation should only take
$curl->setopt(CURLOPT_TIMEOUT, $p->opts->timeout);

$curl->setopt(CURLOPT_URL, ("https://$host:$port$url"));
my @authHeader = ( 'Content-Type: application/json', "ZAPI_KEY: $zapikey");
$curl->setopt(CURLOPT_HTTPHEADER, \@authHeader);

# A filehandle, reference to a scalar or reference to a typeglob can be used here.
$curl->setopt(CURLOPT_WRITEDATA,\$response_body);

# Starts the actual request
$retcode = $curl->perform;

and i modifed with

Code: Select all

#  ZAPI v3 call
my $response_body;
# my $retcode;
my $response_code;
my $response_decoded;
my $curl = WWW::Curl::Easy->new;
$curl->setopt(CURLOPT_HEADER,0);
$curl->setopt(CURLOPT_SSL_VERIFYPEER, 0);
$curl->setopt(CURLOPT_SSL_VERIFYHOST, 0);

# Maximun time that a given cURL operation should only take
$curl->setopt(CURLOPT_TIMEOUT, $p->opts->timeout);

$curl->setopt(CURLOPT_URL, ("https://$host:$port$url"));
my @authHeader = ( 'Content-Type: application/json', "ZAPI_KEY: $zapikey");
$curl->setopt(CURLOPT_HTTPHEADER, \@authHeader);

# A filehandle, reference to a scalar or reference to a typeglob can be used here.
$curl->setopt(CURLOPT_WRITEDATA,\$response_body);

# Starts the actual request
my $retcode = $curl->perform;

Still having the same output:

Can't use an undefined value as filehandle reference at check_zevenet_cpu.pl line 179.

I think there is one more module that did not get updated. Try running this to install the WWW::Curl::Easy module.

Code: Select all

cpan -i WWW::Curl::Easy

Test the check again and see is it works.
Please post how you ran the check.
