NRPE - Environment Variable

[paulol]

Hi there, i'm triyng to set a new path in $PATH variable in /etc/sysconfig/nrpe to NRPE. But it doesn't work...

Code: Select all

vim /etc/sysconfig/nrpe

PATH="/usr/local/rvm/gems/ruby-2.1.5/bin:/usr/local/rvm/gems/ruby-2.1.5@global/bin:/usr/local/rvm/rubies/ruby-2.1.5/bin:/usr/local/rvm/gems/ruby-2.1.5/bin:/usr/local/rvm/gems/ruby-2.1.5@global/bin:/usr/local/rvm/rubies/ruby-2.1.5/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/rvm/bin:/root/bin"
GEM_HOME='/usr/local/rvm/gems/ruby-2.1.5'
GEM_PATH='/usr/local/rvm/gems/ruby-2.1.5:/usr/local/rvm/gems/ruby-2.1.5@global'

IRBRC='/usr/local/rvm/rubies/ruby-2.1.5/.irbrc'
RUBY_VERSION='ruby-2.1.5'

Code: Select all

EnvironmentFile=-/etc/sysconfig/nrpe

Is this a typo? You have "-" in front of the path...

I found a solution.

I removed this variable EnvironmentFile=-/etc/sysconfig/nrpe and I configured the nrpe.cfg to do the following:

Code: Select all

command[check_amazon_metrics]=source /etc/sysconfig/nrpe; rvmsudo /usr/local/nagios/libexec/Amazon/nagios-cloudwatch-master/check_cloudwatch.rb $ARG1$ -C config_app.yml

and I commented in the following line:

Code: Select all

#command_prefix=/usr/bin/sudo

and I configured the /etc/sysconfig/nrpe like this:

Code: Select all

PATH="/usr/local/rvm/gems/ruby-2.1.5/bin:/usr/local/rvm/gems/ruby-2.1.5@global/bin:/usr/local/rvm/rubies/ruby-2.1.5/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/rvm/bin"
export GEM_HOME='/usr/local/rvm/gems/ruby-2.1.5'
export GEM_PATH='/usr/local/rvm/gems/ruby-2.1.5:/usr/local/rvm/gems/ruby-2.1.5@global'
export MY_RUBY_HOME='/usr/local/rvm/rubies/ruby-2.1.5'
export IRBRC='/usr/local/rvm/rubies/ruby-2.1.5/.irbrc'
export RUBY_VERSION='ruby-2.1.5'
