NTP Monitor for 11.x -- With Complete Instructions
Problem this snippet solves:
As the F5 LTM does not come with an NTP health monitor, I began my search for one. I found one here, written for 9.x and spent a few minutes getting it to work in 11.5.4.
Disclaimer: All the hard work was already done, I simply made a few updates to it for 11.x: https://devcentral.f5.com/codeshare/ntp-monitor
How to use this snippet:
- Upload NTP.pm (NTP Library) via FTP to the '/usr/bin/monitors/CPAN/Net' directory (You will have to create the CPAN and Net folders using the 'mkdir' command in UNIX shell).
- Import custom NTP healthcheck file, ntp_mon: 'System >> File Management >> External Monitor Program File List >> Import'
- Local Traffic>> Monitors >> Create
- Name: ntp_monitor
- Type:external
- External Program: ntp_mon
- Bind to pool, and treat like normal health monitor.
- To ensure functionality, temporarily add a host that you know does not serve NTP such as your desktop, to ensure it marks the host down.
