need your suggestion

Hi all:
I need your suggestion about how to making this script
Purpose:-
Monitor log for the system
OS: Unix Sun Solaris 10
Hold oracle database 10 g

Life time for the system cycle to 48 hours

the system working as the follow
1- the system is divided into three steps
2- script run to check some service
3- after checking this services another scripts load data into table in DB

This is some script is repeated into the three step
Like service.sh I must check every step is the first

the scripts make log with this format
LogFileName_`date �+%d_%m_%Y%H%M%S'`

the status of the action in the script programmed with two option
successful or failed

So the only thing is unique with the log file is the time stamp
This is my suggestion to make monitor script

I make lookup table file cause I know what is the script is running and log output
Into each step

And I am trying to build script
1- check if any file add into file directory or not Within the same 48 hours (the duration of the system running)
2- look into the lookup table
3- make awk report show
StepName ScriptRunningName the status

Is what I think for programming my case good or there is some thing also
Please provide me with the steps is general and I will try to programming it
Thanks in advance
Mr Dell
