Hello, no problem, with Ubuntu 18.04 you should start with monit 5.27.0.
To minimze your work on the old Ubunto 14.04 you can use monit 5.19.0. The monit 5.19.0 support the old glibc and kernel used on some old systems (like Sles 11) and the configuration changes are minimal or none regarding to monit 5.16. On the other hand, as long as every thing works well (again), you should stay on monit 5.16. With regards, Lutz
