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.

lsmsad

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

NAME

       lsmsad - Starts the Storage Administrator (SA) daemon

SYNOPSIS

       /usr/sbin/lsmsad

DESCRIPTION

       The SA daemon, lsmsad, is a process required by lsmsa, the SA graphical user interface (GUI). The daemon issues commands and obtains system
       information on behalf of SA.

       The SA daemon runs on a Tru64 UNIX system on which LSM is initialized and running.  The SA client runs on any  machine  that  supports  the
       Java Runtime Environment.

       The SA daemon is automatically started at boot time. Under normal conditions, the daemon does not need to be run manually.

       If SA does not start during the boot process, enter:

       /sbin/init.d/lsmsa stop

       To restart SA, enter:

       /sbin/init.d/lsmsa start

       Only one SA daemon can be running on a system at a given time. If a second SA daemon attempts to start, it will fail.

RESTRICTIONS

       You must be root user to run lsmsad.

FILES

       The script that starts lsmsad at boot time.  The command log file that tracks SA tasks.	The access log file that tracks login to  SA.  The
       server log file that tracks server startup information and server errors.  The log maintenance shell script that saves and  compresses  log
       files.
