logwatchにレポートを週に1回だけ送信させる
3つのシステムでメールに送信されるlogwatchレポートからのノイズを減らしたいと思います。
週の数日だけ、または週に1回だけ送信するようにlogwatchを構成することは可能ですか？

# NOTE:
# All these options are the defaults if you run logwatch with no
# command-line arguments. You can override all of these on the
# command-line.
# You can put comments anywhere you want to. They are effective for the
# rest of the line.
# this is in the format of <name> = <value>. Whitespace at the beginning
# and end of the lines is removed. Whitespace before and after the = sign
# is removed. Everything is case *insensitive*.
# Yes = True = On = 1
# No = False = Off = 0
# Default Log Directory
# All log-files are assumed to be given relative to this directory.
LogDir = /var/log
# You can override the default temp directory (/tmp) here
TmpDir = /var/cache/logwatch
#Output/Format Options
#By default Logwatch will print to stdout in text with no encoding.
#To make email Default set Output = mail to save to file set Output = file
Output = stdout
#To make Html the default formatting Format = html
Format = text
#To make Base64 [aka uuencode] Encode = base64
Encode = none
# Default person to mail reports to. Can be a local account or a
# complete email address. Variable Output should be set to mail, or
# --output mail should be passed on command line to enable mail feature.
MailTo = root
# WHen using option --multiemail, it is possible to specify a different
# email recipient per Host processed. For example, to send the report
# for hostname Host1 to [email protected], use:
#Mailto_Host1 = [email protected]
# Multiple recipients can be specified by separating them with a space.
# Default person to mail reports from. Can be a local account or a
# complete email address.
MailFrom = Logwatch
# if set, the results will be saved in <filename> instead of mailed
# or displayed. Be sure to set Output = file also.
#Filename = /tmp/logwatch
# Use archives? If set to 'Yes', the archives of logfiles
# (i.e. /var/log/messages.1 or /var/log/messages.1.gz) will
# be searched in addition to the /var/log/messages file.
# This usually will not do much if your range is set to just
# 'Yesterday' or 'Today'... it is probably best used with Range = All
# By default this is now set to Yes. To turn off Archives uncomment this.
#Archives = No
# The default time range for the report...
# The current choices are All, Today, Yesterday
Range = Today
# The default detail level for the report.
# This can either be Low, Med, High or a number.
# Low = 0
# Med = 5
# High = 10
Detail = 10
# The 'Service' option expects either the name of a filter
# (in /usr/share/logwatch/scripts/services/*) or 'All'.
# The default service(s) to report on. This should be left as All for
# most people.
Service = All
# You can also disable certain services (when specifying all)
Service = "-zz-network" # Prevents execution of zz-network service, which
# prints useful network configuration info.
Service = "-zz-sys" # Prevents execution of zz-sys service, which
# prints useful system configuration info.
Service = "-eximstats" # Prevents execution of eximstats service, which
# is a wrapper for the eximstats program.
# If you only cared about FTP messages, you could use these 2 lines
# instead of the above:
#Service = ftpd-messages # Processes ftpd messages in /var/log/messages
#Service = ftpd-xferlog # Processes ftpd messages in /var/log/xferlog
# Maybe you only wanted reports on PAM messages, then you would use:
#Service = pam_pwdb # PAM_pwdb messages - usually quite a bit
#Service = pam # General PAM messages... usually not many
# You can also choose to use the 'LogFile' option. This will cause
# logwatch to only analyze that one logfile.. for example:
#LogFile = messages
# will process /var/log/messages. This will run all the filters that
# process that logfile. This option is probably not too useful to
# most people. Setting 'Service' to 'All' above analyzes all LogFiles
# anyways...
#
# By default we assume that all Unix systems have sendmail or a sendmail-like MTA.
# The mailer code prints a header with To: From: and Subject:.
# At this point you can change the mailer to anything that can handle this output
# stream.
# TODO test variables in the mailer string to see if the To/From/Subject can be set
# From here with out breaking anything. This would allow mail/mailx/nail etc..... -mgt
mailer = "/usr/sbin/sendmail -t"
#
# With this option set to a comma separted list of hostnames, only log entries
# for these particular hosts will be processed. This can allow a log Host to
# process only its own logs, or Logwatch can be run once per a set of hosts
# included in the logfiles.
# Example: HostLimit = hosta,hostb,myhost
#
# The default is to report on all log entries, regardless of its source Host.
# Note that some logfiles do not include Host information and will not be
# influenced by this setting.
#
#HostLimit = myhost
# vi: shiftwidth=3 tabstop=3 et
Logwatch.confのRangeパラメータを変更することで、logwatchに1日ではなく7日を表示するように指示できます。
Range = between -7 days and -1 days
Logwatchを毎週のcronディレクトリから毎日のcronディレクトリに移動することで、毎日ではなく毎週実行するように指示できます。
mv /etc/cron.daily/00logwatch /etc/cron.weekly/
あなたが正確にこれを置く必要があるコメントのための十分なポイントがありません：
--range '-7 days'
それ以外の場合は、完全には機能しません。確認のために受信したメールを確認してください。現在の日付と最も古いチェック済みログが表示されます。
