Hey guys i have installed a new nagios XI installation using the vmware image. I am getting the following error

(Return code of 126 is out of bounds - plugin may not be executable)

This is showing on any monitoring device that tries to monitor port bandwidth.

I have this error showing up when i try and monitor both watch guard and cisco switches.

Any ideas which plugin/ plugin location would be causing the issue?

You might check whether the plugin has executable permissions. Doing some Google search I got this from the nagios support forum.

i saw that also earlier in my searches i just didn't think that would help. I figured a stock install of nagios xi using their vmware image would work... I guess that serves me well for assuming haha. Thanks! –  itmanager223 Jun 26 '12 at 3:35


the plugin is executable, but I still gt 126 return code

$ ls -lt /usr/local/nagios/libexec/check_oracle_health -rwxr-xr-x 1 root root ... /usr/local/nagios/libexec/check_oracle_health
