Mark, thanks for your input.

 

Mark, thank you for explaining the Net::NTP section. I Googled it earlier but did not make the connection to the file structure as you explained it. I have no experience with "perl" at this time.

 

I changed the actual directory structure as suggested -> /shared/lib/perl5/Net/NTP.pm. I left the "use lib" statement as per the code in this article (use lib "/shared/lib/perl5";). I used the Configuration Utility to examine the external monitor. I discovered about six instances of invalid characters (was a question mark inside a black diamond). I removed these characters.

 

Tried the monitor again and the members went to red diamond down.

 

Any other thoughts? Thanks!
