ncab2clf(1) User Commands ncab2clf(1)NAMEncab2clf - 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 stdout.
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 for‐
mat 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 speci‐
fied 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 con‐
verting 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.
