Can you provide us with a URL to this guide?

What kind of system is this (OS/architecture)?

Run the following commands and show the output:

Code: Select all

uname -a
cat /etc/*release
locate ndomod
grep 'ndomod\|broker' /usr/local/nagios/etc/nagios.cfg

Note: If the path to nagios.cfg is different on your system, please modify the last command.

Another thing to verify that you copied the version 3 of the ndomodule and not the version 4 copy by mistake. That would cause the error as the symbol: hostescalation_ary for the 4.x version of Nagios.
The symbol: hostescalation_ary
