I have the below script to help with disk space cleanup that finds logs older than a specified number of days (say 10 days). I need it to grab "active" logs as well. Problem is an "active log" will not get archived unless I put in 0 days which I don't want to do, I need to leave the past 10 days, but I need to archive active logs that tend to get large. Like apache logs that do not rotate until a restart of the app. Any ideas? Thanks.
Hello all
Does anyone has an intersting script or a good freeware tool for log rotation that is good for Unix and Linux as well ?
My thanks in advance (4 Replies)
Hello all.
Due to some reason I can not use HUP to rotate needed log files.
So I use the standard method:
cp $file $file.1
cat /dev/null > $file
But if Java application in this time writing the output to $file,
in the beginning of it appears many "^@^@^@^@^@^@".

this logic was working fine till we... (3 Replies)
hi folk,

Hi Guys,
Good morning, I just want to know and collect ideas on this one. Regarding rotation of logs as I've observed it's not consistently functioning. I have a server with 8 Partitions, each partition has a dedicated directory for the logs that is needed and I set it every 5mins (300secs) the... (1 Reply)
Hi All!
I seem to have a problem with log rotation, unless I am doing something wrong, I have type the following command for testing purposes to see if the -s option works but he did not:
logadm -w /var/adm/messages -C 8 -c -s 512k -t '/var/adm/messages.$n' -z 1

I have an application that rotate its log once it reaches 100mb and it keeps a total of 24 logs. I am trying to write a script to run daily to tar up the previous day logs files and move them to a different directory. here is a long listing of the logs in the directory:

In Mavericks, Apple has apparently moved control of log rotation to ASL. There's a 'ttl' value to determine how long log files will stick around for. I can compress them, change the way they're named, limit them by size, etc. But the one thing I cannot find is how to NOT keep one log file per... (0 Replies)

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.
