Write an automated shell program(s) that can create, monitor the log files and report the issues for

Hi ,

Please help me getting this done.


Write an automated shell program(s) that can create, monitor the log files and report the issues for matching pattern.

(i) Conditions for creating log files.
Log file is created with date (example 2010_03_27.log). If the log file size is 10 Mb for a particular day then automatically the log file will be rotated with sequence number (example, on a particular day if the log file crossed 10 MB while the data insert ii n progress, the program should rotate the log file with a sequence number YYYY_MM_DD_sequence_number.log)

(ii) Condition for reading the data for pattern matching
The report with matched pattern should be reported at the earliest for effective business decision. The data that is already processed shouldn't be considered for analysis for pattern matching.

Example file with sample data and mattching patterns

file01.log
Code:
2010-03-18 24:50:50:500: WorkingThread-1:User_Authorization_Failed session-id-10002033
2010-03-18 24:50:50:550: WorkingThread-1:User_Authentication_Failed session-id-10002033
2010-03-18 24:52:50:500: WorkingThread-1:User_Access_Locked session-id-10002033

Analyze the log for following pattern's:
1. Report number of 'User_Authorization_Failed'
2. Report number of 'User_Authentication_Failed'
3. Report number of 'User_Access_Locked'

Thanks

NAME
Log, .Log - Contains the uucp program log files SYNOPSIS
/usr/spool/uucp/.Log DESCRIPTION
The /usr/spool/uucp/.Log directories contain uucp program log files. The uucp program normally places status information about each trans- action in the appropriate log file each time you use the networking utilities facility. All transactions of the uucico and uuxqt daemons are logged in files named for the remote system concerned. The files are stored in a subdirectory of the /usr/spool/uucp/.Log directory named for the daemon involved. Thus, the log files are named with a form of the following: /usr/spool/uucp/.Log/DaemonName/SystemName The uucp and uuto commands call the uucico daemon. The uucico daemon activities for a particular remote system are logged in the System- Name file in the /usr/spool/uucp/.Log/uucico directory on the local system. The uux and uusend commands call the uuxqt daemon. The uuxqt daemon activities for a particular remote system are logged in the SystemName file in the /usr/spool/uucp/.Log/uuxqt directory on the local system. When more than one uucp process is running, however, the system cannot access the standard log file, so it places the status information in a file with a .Log prefix that covers just the single transaction. The uucp program can automatically append the temporary log files to a primary log file. This is called compacting the log files, and is handled by the uudemon.cleanu command, a shell procedure, which combines the log files of the activities of the uucico and uuxqt daemons on a system and stores them in the /usr/spool/uucp/.Old directory. The default is for the uudemon.cleanu command to save log files that are 2 days old. This default can be changed by modifying the appro- priate line in the shell script. If storage space is a problem on a particular system, reduce the number of days that the files are kept in the individual log files. The uulog command can be used to view the uucp program log files.

Daemons: cron, uucico(8), uusched(8) Commands: uucp(1), uudemon.cleanu(4), uulog(1), uusend(1), uuto(1), uux(1) delim off Log(4)
