The usual system to use for log file rotation on Linux is logrotate the man page even includes an example entry for dealing with apache log file rotation.
Note that the logrotate example does a:
of the apache PID, not a restart of apache, perhaps you could try that in your savelog configuration.
The other idea to try is to do a copy truncate, that is copy the current log file to httpd.log.0 (having rolled the previous log files to httpd.log.n+1 first) and then do :
So that the inode number used by apache for the log file does not need to change?

Reason: Extra ideas
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 "^@^@^@^@^@^@".

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,... (2 Replies)

Hi , I have cronolog (http://cronolog.org/) setup to rotate both my error and access logs, but how can I use it to rotate my mod_jk.log file. I tried different things but cant get it to work. I want to end up where all three files will be rotated daily in YYYY/MM/DD folder format. thanks (0 Replies)
Hi
I am trying to create a simple function that implements log rotation
rotatelogs () {
file_name=$1

retention_period=$3
find $archive_dir -name $file_name -mtime +$retention_period -exec rm -f {} \;
}
Issue i am facing is the file_name would be something like my... (3 Replies)
hi folk,
need advise regarding the log rotation, i have the logadm set at

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)

vlogger
VLOGGER(1) User Contributed Perl Documentation VLOGGER(1)NAME
vlogger - flexible log rotation and usage tracking in perl
SYNOPSIS
vlogger [OPTIONS]... [LOGDIR]
DESCRIPTION
Vlogger is designed to make webserver log rotation simple and easy to manage. It deals with VirtualHost logs automatically, so only one
directive is required to manage all hosts on a webserver. Vlogger takes piped output from Apache or another webserver, splits off the
first field, and writes the logs to logfiles in subdirectories. It uses a filehandle cache to avoid resource limitations. It will start a
new logfile at the beginning of a new day, and optionally start new files when a certain filesize is reached. It can maintain a symlink to
the most recent log for easy access. Optionally, host parsing can be disabled for use in ErrorLog directives.
To use vlogger, you need to add a "%v" to the first part of your LogFormat:
LogFormat "%v %h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i"" combined
Then call it from a customlog:
CustomLog "| /usr/sbin/vlogger -s access.log -u www-logs -g www-logs /var/log/apache" combined
OPTIONS
Options are given in short format on the command line.
-a Do not autoflush files. This may improve performance but may break logfile analyzers that depend on full entries in the logs.
-e ErrorLog mode. In this mode, the host parsing is disabled, and the file is written out using the template under the specified
LOGDIR.
-n Disables rotation. This option disables rotation altogether.
-f MAXFILES Maximum number of filehandles to keep open. Defaults to 100. Setting this value too high may result in the system run-
ning out of file descriptors. Setting it too low may affect performance.
-u UID Change user to UID when running as root.
-g GID Change group to GID when running as root.
-t TEMPLATE Filename template using Date::Format codes. Default is "%m%d%Y-access.log", or "%m%d%Y-error.log". When using the -r
option, the default becomes "%m%d%Y-%T-access.log" or "%m%d%Y-%T-error.log".
-s SYMLINK Specifies the name of a symlink to the current file.
-r SIZE Rotate files when they reach SIZE. SIZE is given in bytes.
-d CONFIG Use the DBI usage tracker.
-h Displays help.
-v Prints version information.
DBI USAGE TRACKER
Vlogger can automatically keep track of per-virtualhost usage statistics in a
database. DBI and the relevant drivers (eg. DBD::mysql) needs to be installed for
this to work. Create a table in your database to hold the data. A "mysql_create.sql"
script is provided for using this feature with MySQL. Configure the dsn, user, pass
and dump values in the vlogger-dbi.conf file. The "dump" parameter controls how often
vlogger will dump its stats into the database (the default is 30 seconds). Copy this
file to somewhere convienient on your filesystem (like /etc/apache/vlogger-dbi.conf) and
start vlogger with "-d /etc/apache/vlogger-dbi.conf". You might want to use this feature
to easily bill customers on a daily/weekly/monthly basis for bandwidth usage.
