In my old job, for nagios they had a custom nagios tempting system built off C pre processor macros. You'd edit their custom config syntax, run a "build config" script, and everything would get converted into nagios-readable formats. The thing is: nagios doesn't actually work for more than monitoring about 100 machines. Everything after that is a hack. It's made where you know your systems by hand, are hand configuring everything, and setting up all alerts with love and care and a kiss as you edit every file manually. [This is your brain.] [This is your brain after losing sleep every night for a week because of nagios spurious alerting.]
