Oh heck, why not - here's a slightly improved design. Run it in the background, and it will write the user defined above when it sees the exact phrase (also defined above).

It's not the pertiest, and probably not the fastest if the logs grows very quickly, but it works, and it's be easy to modify to mail, page, whatever...
Just be careful that it doesn't flood you out if it finds the same message hundreds of times...

Code:
#! /bin/ksh

search_word="search terms"
write_user=user_id

tail -n1 -f /path/to/log |&
while read -p output_line; do
 [[ $output_line == *"$search_word"* ]] && {
  print "$output_line" | write $write_user
  }
done

timedsetup

timedsetup(8)						      System Manager's Manual						     timedsetup(8)

NAME

       timedsetup - Performs initial setup of the time server daemon (timed).

SYNOPSIS

       /usr/sbin/timedsetup

DESCRIPTION

       The timedsetup command is an interactive script that can be used to perform initial time service configuration for your system.

       By  default,  timed  does  not start at boot time.  The timedsetup script asks if you want the timed daemon to be started at boot time, and
       prompts you for any options to pass to the timed daemon whenever it is invoked.	The script then starts the timed daemon.

       For more information on the timed options, see the timed(8) reference page.

									  Note

       The timed daemon is provided for compatibility.	Tru64 UNIX also provides support for the Network Time Protocol	(NTP)  through	the  xntpd
       daemon.	 Compaq  recommends  you use NTP for time synchronization.  If your system is configured to run NTP, the timedsetup command passes
       the -E and -M options to the timed daemon by default.

       If you plan to run both the timed daemon and NTP, you should configure NTP first.

RESTRICTIONS

       In configurations with two or more hosts each connected to the same two or more subnetworks, only one of the host can run  the  timed  with
       the -M option.

FILES

       Specifies the command pathname The timed startup and shutdown script Specifies timed parameters pertinent to a specific system

       Commands: timed(8), xntpd(8)
