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--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, respectively.
--logfile log-file-group
This will force Logwatch to process only the set of logfiles
defined by log-file-group (i.e. messages, xferlog, ...). Log‐
watch will therefore process all services that use those log‐
files. 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.
--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 Yes‐
terday, 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/mes‐
sages.?.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 don't want to
use this.
--filename file-name
Save the output to file-name instead of displaying or mailing
it.
--logdir directory
Look in directory for log subdirectories or log files instead of
the default directory.
--hostlimit host1,host2
Limit report to hostname - host1, host2.
--hostname hostname
Use hostname for the reports instead of this system's hostname.
In addition, if HostLimit is set in the logwatch.conf configura‐
tion file (see MORE INFORMATION, below), then only logs from
this hostname will be processed (where appropriate).
--html_wrap num-characters
Number of characters that html output should be wrapped to.
Default is 80.
--numeric
Inhibits additional name lookups, displaying IP addresses numer‐
ically.
--no-oldfiles-log
Suppress the logwatch log, which informs about the old files in
logwatch tmpdir.
--usage
Displays usage information
--help same as --usage.
