There are many components of nagios that rely on the format of these log lines. You'll need to touch all of them if you intend to keep them working. A simple grep to get you started --

$ grep -rl "HOST ALERT" *
base/logging.c
cgi/summary.c
cgi/avail.c
cgi/history.c
cgi/showlog.c
cgi/histogram.c
cgi/trends.c

Perhaps a better/more flexible/more scalable solution would be to write your own event broker module that creates it's own log file (or other integration with netcool) in the format you need.
