18 Logwatch is a customizable, pluggable log-monitoring system. It will
19 go through your logs for a given period of time and make a report in
20 the areas that you wish with the detail that you wish. Logwatch is
21 being used for Linux and many types of UNIX.
22
24 --detail level
25 This is the detail level of the report. level can be a positive
26 integer, or high, med, low, which correspond to the integers 10,
27 5, and 0, respectively.
28 --logfile log-file-group
30 This will force Logwatch to process only the set of logfiles
31 defined by log-file-group (i.e. messages, xferlog, ...). Log‐
32 watch will therefore process all services that use those log‐
33 files. This option can be specified more than once to specify
34 multiple logfile-groups.
35 --service service-name
37 This will force Logwatch to process only the service specified
38 in service-name (i.e. login, pam, identd, ...). Logwatch will
39 therefore also process any log-file-groups necessary to process
40 these services. This option can be specified more than once to
41 specify multiple services to process. A useful service-name is
42 All which will process all services (and logfile-groups) for
43 which you have filters installed.
44 --mailto address
46 Mail the results to the email address or user specified in
47 address.
48 --range range
50 You can specify a date-range to process. Common ranges are Yes‐
51 terday, Today, All, and Help. Additional options are listed
52 when invoked with the Help parameter.
53 --archives
55 Each log-file-group has basic logfiles (i.e. /var/log/messages)
56 as well as archives (i.e. /var/log/messages.? or /var/log/mes‐
57 sages.?.gz). When used with "--range all", this option will
58 make Logwatch search through the archives in addition to the
59 regular logfiles. For other values of --range, Logwatch will
60 search the appropriate archived logs.
61 --debug level
63 For debugging purposes. level can range from 0 to 100. This
64 will really clutter up your output. You probably don't want to
65 use this.
66 --filename file-name
68 Save the output to file-name instead of displaying or mailing
69 it.
70 --logdir directory
72 Look in directory for log subdirectories or log files first
73 before looking in the default directories.
74 --hostlimit host1,host2
76 Limit report to hostname - host1, host2.
77 --hostname hostname
79 Use hostname for the reports instead of this system's hostname.
80 In addition, if HostLimit is set in the logwatch.conf configura‐
81 tion file (see MORE INFORMATION, below), then only logs from
82 this hostname will be processed (where appropriate).
83 --html_wrap num-characters
85 Number of characters that html output should be wrapped to.
86 Default is 80.
87 --hostformat split
89 Use split approach when formatting report for multiple hosts -
90 none [default], split, splitmail.
91 --output output-type
93 Report using output-type - stdout [default], mail, file.
94 --format format
96 Format report using format - text [default], html.
97 --subject email-subject
99 Customize the email subject sent by Logwatch. Option --output
100 must be set to mail.
101 --encode encoding
103 Encode report using encoding - none [default], base64.
104 --numeric
106 Inhibits additional name lookups, displaying IP addresses numer‐
107 ically.
108 --usage
110 Displays usage information
111 --help same as --usage.
