It totally depends on what exactly you want to monitor in your log file. Here is one approach that I want to suggest:-
E.g. if you want to monitor a log for any new occurrence of an exception or error message and it does not have date and time information, then you can go by line number. Each time script find an exception or error message it logs it to a file with date, time & line number information and script uses this file content, compares it during its next run to identify another occurrence.

ncab2clf
ncab2clf(1) User Commands ncab2clf(1)
NAME
ncab2clf - convert binary log file to Common Log File format
SYNOPSIS
/usr/bin/ncab2clf [-Dhv] [-i input-file] [-o output-file]
[-b size] [-n number] [-s datetime]
DESCRIPTION
The ncab2clf command is used to convert the log file generated by the Solaris Network Cache and Accelerator ("NCA") from binary format, to
Common Log File ("CLF") format. If no input-file is specified, ncab2clf uses stdin. If no output-file is specified, the output goes to std-
out.
OPTIONS
-b Specifies the binary-log-file blocking in kilobytes; the default is 64 Kbyte.
-D Specifies that direct I/O be disabled.
-h Prints usage message.
-i input-file Specifies the input file.
-n number Output number CLF records.
-o output-file Specifies the output file.
-s datetime Skip any records before the date and time specified in datetime. You can specify the date and time in CLF format or in
the format specified by the touch(1) utility. CLF format is the dominant format, so ncab2clf first analyzes datetime
assuming CLF.
-v Provides verbose output.
EXAMPLES
Example 1 Converting a Binary File to a Common Log File Format
The following example converts the binary file /var/nca/logs/nca.blf to a file /var/nca/logs/nca.clf, which is in Common Log File format.
example% ncab2clf -D -i /var/nca/logs/nca.blf -o /var/nca/logs/nca.clf
Example 2 Converting Multiple Log Files
The following script may be used to convert multiple log files. The directory designated by "*" must only contain log files.
!/bin/ksh
for filename in *
do
ncab2clf -D < $filename > $filename.clf
done
Example 3 Using -s and -n on a Raw Device
The following example shows how ncab2clf can be used on a raw device. If not using the -n option, the default is to convert all records
from the starting location to the end of the file. The date and time specified with -s, below, is in CLF format.
example% ncab2clf -s '10/Apr/2001:09:23:13' -n 100 < /dev/dsk/c2t1d0s6
EXIT STATUS
The following exit values are returned:
0 The file converted successfully
>0 An error occurred.

NOTES
The binary log files generated by NCA can become very large. When converting these large binary files, use the -b option to the ncab2clf
command to help performance.
Direct I/O is a benefit to the user if the data being written does not come in as large chunks. However, if the user wishes to convert the
log file in large chunks using the -b option, then direct I/O should be disabled by using the -D option.
