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. Easy to use - works right out
of the package on almost all systems.
OPTIONS
- --detal level
-
This is the detail level of the report.
level
can be high, med, low.
- --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.
- --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).
This option will make LogWatch search through the archives in addition
to the regular logfiles. The entries must still be in the proper date
range (see below) to be processed, however.
- --range range
-
You can specify a date-range to process. This option is currently limited
to only
Yesterday, Today
and
All.
- --debug level
-
For debugging purposes.
level
can range from 0 to 100. This will
really
clutter up your output. You probably don't want to use this.
- --save file-name
-
Save the output to
file-name
instead of displaying or mailing it.
- --usage
-
Displays usage information
- --help
-
same as --usage.
FILES
/etc/log.d/logwatch.conf
-
Really a symlink to /etc/log.d/conf/logwatch.conf.
This file sets the default values of all the above
options. These defaults are used when LogWatch is
called without any parameters (i.e. from cron.daily).
The file is well-documented, but the explanations above
also apply to this config file.
/etc/log.d/conf/services/*
-
Configuration files for the various services whose log
entries LogWatch can process.
/etc/log.d/conf/logfiles/*
-
Configuration files for the various logfiles that the
above service's log entries are stored in.
/etc/log.d/scripts/shared/*
-
Filters common to many services and/or logfiles.
/etc/log.d/scripts/logfiles/*
-
Filters specific to just particular logfiles.
/etc/log.d/scripts/services/*
-
Actual filter programs for the various services.
EXAMPLES
logwatch --service ftpd-xferlog --range all --detail high --print --archives
-
This will print out all FTP transfers that are stored in all current and archived
xferlogs.
logwatch --service pam_pwdb --range yesterday --detail high --print
-
This will print out login information for the previous day...
BUGS
The --range option is very weak... this will be fixed in
the future.
