Shell script for continuously monitoring log file

Hi
I have written below log monitoring script to egrep multiple words and redirect the output to a text file and its working fine but I want to add some more below given functionality to it, which is very advance and im not very good in it, so please help if you can Smilie
  1. I am egrepping all the error codes, so I want rather than egrepping all error codes, I should grep for HTTP/1.1 200 which is successful code and which ever line does not have this redirects output to output file.
  2. ignore any line which has /akamai/sureroute
  3. right now I am using cron to run this script every 5 min, so my script will send the same error again and again, so I want the script not to send the same error more than 3 times. (based on the time stamp).
  4. for e.g. if server goes down I do not want 1000's error messages, so if there are more than 100 error messages, script should send only 1 mail.
=====================================

Code:
find /home/bharat/ -type f -name "apache_logs.txt" |while read file
  do
    RESULT=$(egrep "[^0](400|401|403|404|405|406|407|408|409|410|411|412|413|414|415|416|417|418|422|425|426|428|429|431|451|500|501|502|503|504|505|511)" $file)
      if [[ ! -z $RESULT ]]
         then
            echo "Error(s) in $file on $HOSTNAME at "$(date)": $RESULT">> email_result.txt
     fi
  done

NAME
ip-monitor, rtmon - state monitoring SYNOPSIS
ip monitor [ all | LISTofOBJECTS ] DESCRIPTION
The ip utility can monitor the state of devices, addresses and routes continuously. This option has a slightly different format. Namely, the monitor command is the first in the command line and then the object list follows: ip monitor [ all | LISTofOBJECTS ] OBJECT-LIST is the list of object types that we want to monitor. It may contain link, address and route. If no file argument is given, ip opens RTNETLINK, listens on it and dumps state changes in the format described in previous sections. If a file name is given, it does not listen on RTNETLINK, but opens the file containing RTNETLINK messages saved in binary format and dumps them. Such a history file can be generated with the rtmon utility. This utility has a command line syntax similar to ip monitor. Ide- ally, rtmon should be started before the first network configuration command is issued. F.e. if you insert: rtmon file /var/log/rtmon.log in a startup script, you will be able to view the full history later. Certainly, it is possible to start rtmon at any time. It prepends the history with the state snapshot dumped at the moment of starting. SEE ALSO
