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 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.
