Please help with monitoring stuff

Hi,

I am trying to write a script to do monitoring kind of stuff,

requirement - when a server is given a start it updates a file called server.log, I need to keep on grepping the word "Running" and as soon as it comes , script should be exited with the message , "Server came up successfully else it shoud wait for "Running" untill 7 minuts, and then should time out with the message "script timed out"

My idea is to use tail -f server.log | grep "Running" , but im not sure how will this exit because tail will wait for the input into server.log

for timinig out I think best I can use is sleep

so it shoud be

Code:

 
while ( i < 420 )
do 
   tail -f server.log | grep "Running"   //(the problematic area)
   if [ $? == 0 ]
    then   
           echo "Server came up succesfully"
           exit 0
i++
done
echo "script timed out"

PLease suggest. if my logic is wrong or i have placed wrong commands.

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
