Thanks for the link.

Have followed the instructions and installed the plugin.
However, when i run it , I am getting the below PERL module error.

Code: Select all
./check_nwc_health --help
Can't locate Module/Load.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at ./check_nwc_health line 2747.


I think some dependency package of perl is required. Can I go ahead and install (how?) ? Will that hamper the existing Nagios monitoring?
I am worried as I have no test lab and trying out this in PROD nagios server.

Regards.

Try installing the missing perl module by running:

Code: Select all
yum install perl-Module-Load


Let us know if this helped.

What operating system and version are you running?

Or you could compile it from here

Hi,

we are using : CentOS Linux release 7.5.1804 (Core)

We need to write script for compiling this load.pm ? or just need copy the files. Please suggest.

Thanks :)
Installation done.

I have tested the below command from nagios terminal for checking the load and getting the error as stated below.
Could you please let me know, if I am missing anything in the arguments.

Code: Select all
/usr/local/nagios/libexec/check_nwc_health -v --mode cpu-load --domain tcp --hostname host  --port 161  --username user --authpassword authpswd --authprotocol sha --privpassword authpswd  --privprotocol aes

CRITICAL - cannot create session object: Unable to resolve the TCP/IPv4 address "AUM1FWL-PRI001"
