Nagios Support Forum

Hello,

I am trying to monitor Oracle instances using Nagios and the same error code keeps on returning.

I have re-ran the commands however the same output is displayed. On the troubleshooting guide it states to use the check_foo command which isn't present on the remote server.

I would've thought that this would be a default command as we have upgraded our Nagios instance, however is this not the case?

Thank you in advance.

Hello @Chris Watson

Thanks for reaching out, typically when we see a 'Return Code 127' indicates that the plugin may be missing. Please review the following article:

Please let us know how things look,
