Please find attached output from the command

I think the require 'rubygems' in your check_cloudwatch_status is the issue. I had this problem using ruby modules, but it was the 'rubygems' that fixed a require dependancy. Are you certain you have the gem that this file is referring to installed?

Please find below details, because even after installing rubygems the problem persist.

If I try to execute a command from the Nagios Server, I get the below error.

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require': no such file to load -- AWS (LoadError)

Run these commands in green, just for sanity:

[root@localhost snmp]# irb -rpp
irb(main):001:0> pp $LOAD_PATH
["/usr/lib/ruby/site_ruby/1.8",
"/usr/lib64/ruby/site_ruby/1.8",

"/usr/lib/ruby/1.8",
"/usr/lib64/ruby/1.8",
"/usr/lib64/ruby/1.8/x86_64-linux",
"."]
=> nil

If this all prints out fine, try adding this gem from the linux command line: Source: https://rubygems.org/gems/aws

I already got the problem resolved by running the following command:

gem install CloudyScripts
mkdir /etc/cloutomate/
ssh-keygen -f /etc/cloutomate/cloutomate.pem
Enter blank passphrase
chown nagios:nagios cloutomate.pem


Thank you everyone for the response to my query.

Awesome, thanks for letting us know.
