Nagios "Return Code of 127 is out of bounds - plugin may be missing"


For this tutorial I assume you've installed Nagios. I suggest you install Nagios using the script from  

http://systemadministratorrecipes.blogspot.com/2012/06/scripts-nagios-for-install-on-ubuntu.html 

After installing Nagios. Start it and you will receive the following error:

 "Return code of 127 is out of bounds - plugin may be missing"

 To fix this error follow these instructions:

Step 1 

 Checks that Nagios plugins are installed correctly in the "libexec"
  1. Open "bash-Konsole", and type "sudo su" without quotes, then press Enter key.
  2. Type the administrator password.
  3. Type "cd /usr/local/nagios/libexec" without quotes, and press Enter key.
  4. Type "dir" without quotes, then press Enter key 
 This command should show you Nagios plugins installed. If the folder is empty performs Step 2

Step 2

Let's copy the plugins installed in "/ usr / lib / nagios / plugings" to "/ usr / local / nagios / libexec"
  1. In the open "bash-Konsole", type "mv /usr/lib/nagios/plugins/* /usr/local/nagios/libexec" without quotes, then press Enter key.
  2. Type "sudo /etc/init.d/nagios restart" without quotes, then press Enter key.
Now open browser type http://localhost/nagios and log in.

 After that, Nagios start working properly ;)

    Doesn't work with me! I use the ubuntu 12.04 server and Nagios Version 3.5.0. Doesn't exists the /usr/lib/nagios/plugins directory! But... in my server is /usr/local/nagios/nagios-plugins-1.4.16 ... i copied the plugins to the libexec directory... but doesn't work... any idea?

      Then the plugins was not properly installed. I suggest you go to the link "http://systemadministratorrecipes.blogspot.com/2012/06/scripts-nagios-for-install-on-ubuntu.html" and run the script for reinstall Nagios...

    We have Nagios installed on Centos and all our plugins are in /usr/lib/nagios/plugins dir and everything has been working fine for the past few years. Now I've added a new custom check and it works perfectly fine in command line, but gives the same error (Return Code of 127..) in GUI. We do not have /usr/local/nagios/libexec dir at all. Any suggestions..?

      Check if your are missing some SNMP packages:

      net-snmp-libs-x.x.x
      net-snmp-x.x.x
      net-snmp-utils-x.x.x

      for that, run this command:

      rpm -qa | grep net-snmp

      If this command does nor return anything, then you need install the packages using your package manager.

      After you are done run the command "rpm -qa | grep net-snmp" again to verify that the packages are installed:

      net-snmp-libs-5.5-37.el6_2.1.i686
      net-snmp-5.5-37.el6_2.1.i686
      net-snmp-utils-5.5-37.el6_2.1.i686

      Now you need to stop Nagios to recompile and re-install the Nagios Plug-ins

      for that, go to the folder where the plug-ins are download:

      /configure --with-nagios-user=nagios --with-nagios-group=nagios

      make

      make install

      service nagios start

      :-)
