Is there anything that needs to be done to ensure perl is working? Can the script (external monitor and NTP.pm) be tested from the command line to directly test functionality of the script between the F5 and the NTP server? If so, how?

 

At a quick glance (being new to perl), it looks like I'd have to copy the external monitor file over to the F5 as a perl script (such as TFTPing mon_ntp to /var/tmp/test/mon_ntp.pl), perhaps modify the script so that the arguments (IP and Port) are hard-coded, and call the script (/usr/bin/perl /var/tmp/test/mon_ntp.pl). Sound about right? Is there an easier way to test this and see the results/errors?

 

Thanks in advance!
