Can you ask the author the version numbers of the packages they are using?

That is the version that is installed on your server which the author of the plugin says is too old, what version is he using?

That's the version of the Plugin's Owner.

Hi, I can confirm the check_zevenet_cpu.pl works properly, see output:

root@server:/zevenet-nagios-plugins/libexec# ./check_zevenet_cpu.pl -H 192.168.100.123 -z asdfl9io3dk -c90:100 -w40:50
ZEVENET_CPU WARNING - Zevenet ADC Load Balancer CPU usage is 0 % (100 % idle) | Idle=100%;4050;90100 IOWait=0%;; IRQ=0%;; Nice=0%;; SoftIRQ=0%;; Sys=0%;; Usage=0%;; User=0%;; Total=100%;;

googling you can see that the error message is related to curl module perl.

Can't use an undefined value as filehandle reference at

My current version is
libwww-curl-perl 4.17-4

I have 4.17 on my Centos6 system but I updated the package using cpan.
Try this command to install a newer version of the perl module.

Code: Select all

cpan -i WWW::Curl

i'm behind a proxy with authentication. Can it be the reason?

Re: ZEVENET Monitoring not returning Data

To enable CPAN behind proxy, invoke CPAN Shell as

Code: Select all

perl -MCPAN -e shell
will give you prompt as
cpan[2]>
Now we have to set the proxy type following command

Code: Select all

cpan[2]> o conf init /proxy/
If you're accessing the net via proxies, you can specify them in the
CPAN configuration or via environment variables. The variable in
the $CPAN::Config takes precedence.

Code: Select all

 
Your ftp_proxy? [a.b.c.d] a.b.c.d:port

Code: Select all

Your http_proxy? [a.b.c.d] a.b.c.d:port

Code: Select all

Your no_proxy? [] a.b.c.d:port
If your proxy is an authenticating proxy, you can store your username
permanently. If you do not want that, just press RETURN. You will then
be asked for your username in every future session.

Code: Select all

Your proxy user id? []
Please remember to call 'o conf commit' to make the config permanent!

Code: Select all

cpan[3]> o conf commit
