Alert log not update every time.
My Script . This check log file size every 1 minute.

Code:
#! /bin/bash


logFiles="log1.log log2.log"
logLocation="/usr/home/test/log/"
sleepTime=60


failMessage=":: Log not running :: Pls Check Service"
successMessage="OK"

arr=($logFiles)

arrlen=${#arr[@]}
arrcount=()

date
for ((count=0; count<arrlen; count++)) ; do
    arrcount[$count]=`ls -l  $logLocation${arr[$count]}  |awk '{print $5}'`
    echo "${arr[$count]} Original size :: ${arrcount[$count]}"
done
echo

while [ "e" == "e" ] ; do 
    sleep $sleepTime
    date
    for ((count=0; count<arrlen; count++)) ; do
        nc=`ls -l  $logLocation${arr[$count]}  |awk '{print $5}'`
        echo -n "${arr[$count]} "
        if [ $nc == ${arrcount[$count]} ] ; then
            echo $failMessage
        else
            arrcount[$count]=$nc
            echo $successMessage
        fi
    done
    echo
done

Ex. out put my script.
Code:
Fri Mar 11 02:09:28 ICT 2011

LEARN ABOUT NETBSD

log2

LOG(3)							   BSD Library Functions Manual 						    LOG(3)

NAME

     log, logf, log10, log10f, log1p, log1pf log2, log2f, -- logarithm functions

LIBRARY

     Math Library (libm, -lm)

SYNOPSIS

     #include <math.h>

     double
     log(double x);

     float
     logf(float x);

     double
     log10(double x);

     float
     log10f(float x);

     double
     log1p(double x);

     float
     log1pf(float x);

     double
     log2(double x);

     float
     log2f(float x);

DESCRIPTION

     The following functions compute logarithms:

       o   The log() and logf() functions return the natural logarithm.

       o   The log10() and log10f() functions return the base 10 logarithm.

       o   The log1p() and log1pf() functions return the natural logarithm of (1.0 + x) accurately even for very small values of x.

       o   The log2() and log2f() functions return the base 2 logarithm.

RETURN VALUES

     Upon successful completion, the functions return the logarithm of x as descibed above.  Otherwise the following may occur:

	   1.	If x is NaN, all functions return NaN.

	   2.	If x is positive infinity, all functions return x.  If x is negative infinity, all functions return NaN.

	   3.	If x is +0.0 or -0.0, the log(), log10(), and log2() families return either -HUGE_VAL, -HUGE_VALF, or -HUGE_VALL, whereas the
		log1p() family returns x.

	   4.	If x is +1.0, the log(), log10(), and log2() families return +0.0.  If x is -1.0, the log1p() family returns -HUGE_VAL,
		-HUGE_VALF, or -HUGE_VALL.

     In addition, on a VAX, errno is set to EDOM and the reserved operand is returned by log() unless x > 0, by log1p() unless x > -1.

SEE ALSO

     exp(3), ilogb(3), math(3)

STANDARDS

     The described functions conform to ISO/IEC 9899:1999 (``ISO C99'').

HISTORY

     The history of the logarithm functions dates back to Version 6 AT&T UNIX.
