logwatch - Unix, Linux Command
NAME
logwatch - system log analyzer and reporter
SYNOPSIS
logwatch [--detail level ] [--logfile log-file-group ] [--service service-name ] [--print] [--mailto address ] [--archives] [--range range ] [--debug level ] [--save file-name ] [--logdir directory ] [--hostname hostname ] [--splithosts] [--multiemail] [--output output-type ] [--numeric] [--no-oldfiles-log] [--version] [--help] DESCRIPTION
Logwatch is a customizable, pluggable log-monitoring system. It will go
through your logs for a given period of time and make a report in the areas
that you wish with the detail that you wish. Logwatch is being used for
Linux and many types of UNIX.
OPTIONS
Tag | Description |
--detail level
|
This is the detail level of the report.
level can be a positive integer, or high, med, low, which correspond to the
integers 10, 5, and 0, repectively.
|
--logfile log-file-group
|
This will force Logwatch to process only the set of logfiles
defined by
log-file-group (i.e. messages, xferlog, ...). Logwatch will therefore process
all services that use those logfiles. This option can be specified
more than once to specify multiple logfile-groups.
|
--service service-name
|
This will force Logwatch to process only the service specified in
service-name (i.e. login, pam, identd, ...). Logwatch will therefore also process
any log-file-groups necessary to process these services. This option
can be specified more than once to specify multiple services to process.
A useful
service-name is
All which will process all services (and logfile-groups) for which you have
filters installed.
|
--print
|
Print the results to stdout (i.e. the screen).
|
--mailto address
|
Mail the results to the email address or user specified in
address. |
--range range
|
You can specify a date-range to process. Common ranges are
Yesterday, Today, All, and
Help. Additional options are listed when invoked with the
Help parameter.
|
--archives
|
Each log-file-group has basic logfiles (i.e. /var/log/messages) as
well as archives (i.e. /var/log/messages.? or /var/log/messages.?.gz).
When used with "--range all", this option will make Logwatch search
through the archives in addition to the regular logfiles. For other
values of --range, Logwatch will search the appropriate archived logs.
|
--debug level
|
For debugging purposes.
level can range from 0 to 100. This will
really clutter up your output. You probably dont want to use this.
|
--save file-name
|
Save the output to
file-name instead of displaying or mailing it.
|
--logdir directory
|
Look in
directory for log files instead of the default directory.
|
--hostname hostname
|
Use
hostname for the reports instead of this systems hostname. In addition,
if HostLimit is set in the logwatch.conf configuration file (see
MORE INFORMATION, below),
then only logs from this hostname will be processed (where appropriate).
|
--numeric
|
Inhibits additional name lookups, displaying IP addresses numerically.
|
--no-oldfiles-log
|
Suppress the logwatch log, which informs about the
old files in logwatch tmpdir.
|
--help
|
Displays usage information.
|
FILES
Tag | Description |
/usr/share/logwatch/
|
This directory contains all the perl executables and
configuration files shipped with the logwatch distribution.
|
/etc/logwatch
|
