我想减少logwatch在三个系统上发送到我的电子邮件的报告的噪音。
是否可以将 logwatch 配置为仅在一周中的某些天发送或每周发送一次？

# 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
答案1
Range您可以通过更改logwatch.conf 中的参数来告诉 logwatch 查看 7 天而不是 1 天：
Range = between -7 days and -1 days
您可以通过将 logwatch 从每日 cron 目录移动到每周 cron 目录来告诉 logwatch 每周运行而不是每日运行：
mv /etc/cron.daily/00logwatch /etc/cron.weekly/
答案2
只是为了扩展，你需要把这个放在命令行版本：
logwatch <options> --range '-7 days'
检查您收到的确认邮件，它应该显示当前日期和最早的检查日志。
