AMAVIS-LOGWATCH(1) AMAVIS-LOGWATCH(1)
NAME
amavis-logwatch - An Amavisd-new log parser and analysis utility
SYNOPSIS
amavis-logwatch [options] [logfile ...]
DESCRIPTION
The amavis-logwatch(1) utility is an Amavisd-new log parser that pro-
duces summaries, details, and statistics regarding the operation of
Amavisd-new (henceforth, simply called Amavis).
This utility can be used as a standalone program, or as a Logwatch fil-
ter module to produce Amavisd-new summary and detailed reports from
within Logwatch.
Amavis-logwatch is able to produce a wide range of reports with data
grouped and sorted as much as possible to reduce noise and highlight
patterns. Brief summary reports provide a quick overview of general
Amavis operations and message delivery, calling out warnings that may
require attention. Detailed reports provide easy to scan, hierarchi-
cally-arranged and organized information, with as much or little detail
as desired.
Much of the interesting data is available when Amavis' $log_level is
set to at least 2. See Amavis Log Level below.
Amavis-logwatch outputs two principal sections: a Summary section and a
Detailed section. For readability and quick scanning, all event or hit
counts appear in the left column, followed by brief description of the
event type, and finally additional statistics or count representations
may appear in the rightmost column.
The following segment from a sample Summary report illustrates:

The report indicates there were 9 general warnings, and Amavis scanned
a total of 20313 messages for a total of 1008.53 megabytes or
1,057,524,252 bytes. The next summary groups shows the Blocked /
Passed overview, with 1190 Blocked messages (broken down as 18 messages
blocked as malware, 4 messages with banned names, 416 spam messages,
and 752 discarded messages), and 19123 Passed messages (47 messages
with bad headers and 19076 clean messages).
The next (optional) summary grouping shows message disposition by con-
tents category. There were 18 malware messages and 4 banned file mes-
sages (all blocked), 1168 Spam messages, of which 416 were blocked
(quarantined) and 752 discarded. Finally, there were 19123 messages
consdidered to be Ham (i.e. not spam), 47 of which contained bad head-
ers.
Additional count summaries for a variety of events are also listed.
There are dozens of sub-sections available in the Detailed report, each
of whose output can be controlled in various ways. Each sub-section
attempts to group and present the most meaningful data at superior lev-
els, while pushing less useful or noisy data towards inferior levels.
The goal is to provide as much benefit as possible from smart grouping
of data, to allow faster report scanning, pattern identification, and
problem solving. Data is always sorted in descending order by count,
and then numerically by IP address or alphabetically as appropriate.
The following Spam blocked segment from a sample Detailed report illus-
trates the basic hierarchical level structure of amavis-logwatch:

...
The amavis-logwatch utility reads from STDIN or from the named Amavis
logfile. Multiple logfile arguments may be specified, each processed
in order. The user running amavis-logwatch must have read permission
on each named log file.
Options
The options listed below affect the operation of amavis-logwatch.
Options specified later on the command line override earlier ones. Any
option may be abbreviated to an unambiguous length.
--[no]autolearn
Enables (disables) output of the autolearn report. This report
is only available if the default Amavis $log_templ has been mod-
ified to provide autolearn results in log entries. This can be
done by uncommenting two lines in the Amavis program itself
(where the default log templates reside), or by correctly adding
the $log_templ variable to the amavisd.conf file. See Amavis'
README.customize and search near the end of the Amavisd program
for "autolearn".
-f config_file
--config_file config_file
Use an alternate configuration file config_file instead of the
default. This option may be used more than once. Multiple con-
figuration files will be processed in the order presented on the
command line. See CONFIGURATION FILE below.
--debug keywords
Output debug information during the operation of amavis-log-
watch. The parameter keywords is one or more comma or space
separated keywords. To obtain the list of valid keywords, use
--debug xxx where xxx is any invalid keyword.
--detail level
Sets the maximum detail level for amavis-logwatch to level.
This option is global, overriding any other output limiters
described below.
The amavis-logwatch utility produces a Summary section, a
Detailed section, and additional report sections. With level
less than 5, amavis-logwatch will produce only the Summary sec-
tion. At level 5 and above, the Detailed section, and any addi-
tional report sections are candidates for output. Each incre-
mental increase in level generates one additional hierarchical
sub-level of output in the Detailed section of the report. At
level 10, all levels are output. Lines that exceed the maximum
report width (specified with max_report_width) will be cut.
Setting level to 11 will prevent lines in the report from being
cut (see also --line_style).
--[no]first_recip_only
Specifies whether or not to sort by, and show, only the first
recipient when a scanned messages contains multiple recipients.
--help Print usage information and a brief description about command
line options.
--ipaddr_width width
Specifies that IP addresses in address/hostname pairs should be
printed with a field width of width characters. Increasing the
default may be useful for systems using long IPv6 addresses.
-l limiter=levelspec
--limit limiter=levelspec
Sets the level limiter limiter with the specification levelspec.
--line_style style
Specifies how to handle long report lines. Three styles are
available: full, truncate, and wrap. Setting style to full will
prevent cutting lines to max_report_width; this is what occurs
when detail is 11 or higher. When style is truncate (the
default), long lines will be truncated according to
max_report_width. Setting style to wrap will wrap lines longer
than max_report_width such that left column hit counts are not
obscured. This option takes precedence over the line style
implied by the detail level. The options --full, --truncate,
and --wrap are synonyms.
--nodetail
Disables the Detailed section of the report, and all supplemen-
tal reports. This option provides a convenient mechanism to
quickly disable all sections under the Detailed report, where
subsequent command line options may re-enable one or more sec-
tions to create specific reports.
--sarules `S,H'
--sarules default
Enables the SpamAssassin Rules Hit report. The comma-separated
S and H arguments are top N values for the Spam and Ham reports,
respectively, and can be any integer greater than or equal to 0,
or the keyword all. The keyword default uses the built-in
default values.
--nosarules
Disables the SpamAssassin Rules Hit report.
--sa_timings nrows
Enables the SpamAssassin Timings percentiles report. The report
can be limited to the top N rows with the nrows argument. This
report requires Amavis 2.6+ and SpamAssassin 3.3+.
--sa_timings_percentiles `P1 [P2 ...]'
Specifies the percentiles shown in the SpamAssassin Timings
report. The arguments P1 ... are integers from 0 to 100 inclu-
sive. Their order will be preserved in the report.
--nosa_timings
Disables the SpamAssassin Timings report.
--version
Print amavis-logwatch version information.
--score_frequencies `B1 [B2 ...]'
--score_frequencies default
Enables the Spam Score Frequency report. The arguments B1 ...
are frequency distribution buckets, and can be any real numbers.
Their order will be preserved in the report. The keyword
default uses the built-in default values.
--noscore_frequencies
Disables the Spam Score Frequency report.
--score_percentiles `P1 [P2 ...]'
--score_percentiles default
Enables the Spam Score Percentiles report. The arguments P1 ...
specify the percentiles shown in the report, and are integers
from 0 to 100 inclusive. The keyword default uses the built-in
default values.
--noscore_percentiles
Disables the Spam Score Percentiles report.
--[no]sect_vars
--[no]show_sect_vars
Enables (disables) supplementing each Detailed section title
with the name of that section's level limiter. The name dis-
played is the command line option (or configuration file vari-
able) used to limit that section's output. With the large num-
ber of level limiters available in amavis-logwatch, this a con-
venient mechanism for determining exactly which level limiter
affects a section.
--[no]startinfo
Enables (disables) the Amavis startup report showing most recent
Amavis startup details.
--nosummary
Disables the Summary section of the report.
--syslog_name namepat
Specifies the syslog service name that amavis-logwatch uses to
match syslog lines. Only log lines whose service name matches
the perl regular expression namepat will be used by amavis-log-
watch; all non-matching lines are silently ignored. This is
useful when a pre-installed Amavis package uses a name other
than the default (amavis).
Note: if you use parenthesis in your regular expression, be sure
they are cloistering and not capturing: use (?:pattern) instead
of (pattern).
--timings percent
Enables the Amavis Scan Timings percentiles report. The report
can be top N-percent limited with the percent argument.
--timings_percentiles `P1 [P2 ...]'
Specifies the percentiles shown in the Scan Timings report. The
arguments P1 ... are integers from 0 to 100 inclusive. Their
order will be preserved in the report.
--notimings
Disables the Amavis Scan Timings report.
--version
Print amavis-logwatch version information.
Level Limiters
The output of every section in the Detailed report is controlled by a
level limiter. The name of the level limiter variable will be output
when the sect_vars option is set. Level limiters are set either via
command line in standalone mode with --limit limiter=levelspec option,
or via configuration file variable $amavis_limiter=levelspec. Each
limiter requires a levelspec argument, which is described below in
LEVEL CONTROL.
The list of level limiters is shown below.

LEVEL CONTROL
The Detailed section of the report consists of a number of sub-sec-
tions, each of which is controlled both globally and independently.
Two settings influence the output provided in the Detailed report: a
global detail level (specified with --detail) which has final (big ham-
mer) output-limiting control over the Detailed section, and sub-section
specific detail settings (small hammer), which allow further limiting
of the output for a sub-section. Each sub-section may be limited to a
specific depth level, and each sub-level may be limited with top N or
threshold limits. The levelspec argument to each of the level limiters
listed above is used to accomplish this.
It is probably best to continue explanation of sub-level limiting with
the following well-known outline-style hierarchy, and some basic exam-
ples:
level 0
level 1
level 2
level 3
level 4
level 4
level 2
level 3
level 4
level 4
level 4
level 3
level 4
level 3
level 1
level 2
level 3
level 4
The simplest form of output limiting suppresses all output below a
specified level. For example, a levelspec set to "2" shows only data
in levels 0 through 2. Think of this as collapsing each sub-level 2
item, thus hiding all inferior levels (3, 4, ...), to yield:
level 0
level 1
level 2
level 2
level 1
level 2
Sometimes the volume of output in a section is too great, and it is
useful to suppress any data that does not exceed a certain threshold
value. Consider a dictionary spam attack, which produces very lengthy
lists of hit-once recipient email or IP addresses. Each sub-level in
the hierarchy can be threshold-limited by setting the levelspec appro-
priately. Setting levelspec to the value "2::5" will suppress any data
at level 2 that does not exceed a hit count of 5.
Perhaps producing a top N list, such as top 10 senders, is desired. A
levelspec of "3:10:" limits level 3 data to only the top 10 hits.
With those simple examples out of the way, a levelspec is defined as a
whitespace- or comma-separated list of one or more of the following:
l Specifies the maximum level to be output for this sub-section,
with a range from 0 to 10. if l is 0, no levels will be output,
effectively disabling the sub-section (level 0 data is already
provided in the Summary report, so level 1 is considered the
first useful level in the Detailed report). Higher values will
produce output up to and including the specified level.
l.n Same as above, with the addition that n limits this section's
level 1 output to the top n items. The value for n can be any
integer greater than 1. (This form of limiting has less utility
than the syntax shown below. It is provided for backwards com-
patibility; users are encouraged to use the syntax below).
l:n:t This triplet specifies level l, top n, and minimum threshold t.
Each of the values are integers, with l being the level limiter
as described above, n being a top n limiter for the level l, and
t being the threshold limiter for level l. When both n and t
are specified, n has priority, allowing top n lists (regardless
of threshold value). If the value of l is omitted, the speci-
fied values for n and/or t are used for all levels available in
the sub-section. This permits a simple form of wildcarding (eg.
place minimum threshold limits on all levels). However, spe-
cific limiters always override wildcard limiters. The first
form of level limiter may be included in levelspec to restrict
output, regardless of how many triplets are present.
All three forms of limiters are effective only when amavis-logwatch's
detail level is 5 or greater (the Detailed section is not activated
until detail is at least 5).
See the EXAMPLES section for usage scenarios.
CONFIGURATION FILE
Amavis-logwatch can read configuration settings from a configuration
file. Essentially, any command line option can be placed into a con-
figuration file, and these settings are read upon startup.
Because amavis-logwatch can run either standalone or within Logwatch,
to minimize confusion, amavis-logwatch inherits Logwatch's configura-
tion file syntax requirements and conventions. These are:
o White space lines are ignored.
o Lines beginning with # are ignored
o Settings are of the form:
option = value
o Spaces or tabs on either side of the = character are ignored.
o Any value protected in double quotes will be case-preserved.
o All other content is reduced to lowercase (non-preserving, case
insensitive).
o All amavis-logwatch configuration settings must be prefixed with
"$amavis_" or amavis-logwatch will ignore them.
o When running under Logwatch, any values not prefixed with
"$amavis_" are consumed by Logwatch; it only passes to amavis-log-
watch (via environment variable) settings it considers valid.
o The values True and Yes are converted to 1, and False and No are
converted to 0.
o Order of settings is not preserved within a configuration file
(since settings are passed by Logwatch via environment variables,
which have no defined order).
To include a command line option in a configuration file, prefix the
command line option name with the word "$amavis_". The following con-
figuration file setting and command line option are equivalent:
$amavis_Line_Style = Truncate
--line_style Truncate
Level limiters are also prefixed with $amavis_, but on the command line
are specified with the --limit option:
$amavis_SpamBlocked = 2
--limit SpamBlocked=2
The order of command line options and configuration file processing
occurs as follows: 1) The default configuration file is read if it
exists and no --config_file was specified on a command line. 2) Con-
figuration files are read and processed in the order found on the com-
mand line. 3) Command line options override any options already set
either via command line or from any configuration file.
Command line options are interpreted when they are seen on the command
line, and later options will override previously set options.
EXIT STATUS
The amavis-logwatch utility exits with a status code of 0, unless an
error occurred, in which case a non-zero exit status is returned.
EXAMPLES
Running Standalone
Note: amavis-logwatch reads its log data from one or more named Amavis
log files, or from STDIN. For brevity, where required, the examples
below use the word file as the command line argument meaning
/path/to/amavis.log. Obviously you will need to substitute file with
the appropriate path.
To run amavis-logwatch in standalone mode, simply run:
amavis-logwatch file
A complete list of options and basic usage is available via:
amavis-logwatch --help
To print a summary only report of Amavis log data:
amavis-logwatch --detail 1 file
To produce a summary report and a one-level detail report for May 25th:
grep 'May 25' file | amavis-logwatch --detail 5
To produce only a top 10 list of Sent email domains, the summary report
and detailed reports are first disabled. Since commands line options
are read and enabled left-to-right, the Sent section is re-enabled to
level 1 with a level 1 top 10 limiter:
amavis-logwatch --nosummary --nodetail \
--limit spamblocked '1 1:10:' file
The following command and its sample output shows a more complex level
limiter example. The command gives the top 4 spam blocked recipients
(level 1), and under with each recipient the top 2 sending IPs (level
2) and finally below that, only envelope from addresses (level 3) with
hit counts greater than 6. Ellipses indicate top N or threshold-lim-
ited data:
amavis-logwatch --nosummary --nodetail \
--limit spamblocked '1:4: 2:2: 3::6' file

Running within Logwatch
Note: Logwatch versions prior to 7.3.6, unless configured otherwise,
required the --print option to print to STDOUT instead of sending
reports via email. Since version 7.3.6, STDOUT is the default output
destination, and the --print option has been replaced by --output std-
out. Check your configuration to determine where report output will be
directed, and add the appropriate option to the commands below.
To print a summary report for today's Amavis log data:
logwatch --service amavis --range today --detail 1
To print a report for today's Amavis log data, with one level
of detail in the Detailed section:
logwatch --service amavis --range today --detail 5
To print a report for yesterday, with two levels of detail in the
Detailed section:
logwatch --service amavis --range yesterday --detail 6
To print a report from Dec 12th through Dec 14th, with four levels of
detail in the Detailed section:
logwatch --service amavis --range \
'between 12/12 and 12/14' --detail 8
To print a report for today, with all levels of detail:
logwatch --service amavis --range today --detail 10
Same as above, but leaves long lines uncropped:
logwatch --service amavis --range today --detail 11
Amavis Log Level
Amavis provides additional log information when the variable $log_level
is increased above the default 0 value. This information is used by
the amavis-logwatch utility to provide additional reports, not avail-
able with the default $log_level=0 value. A $log_level of 2 is sug-
gested.
If you prefer not to increase the noise level in your main mail or
Amavis logs, you can configure syslog to log Amavis' output to multiple
log files, where basic log entries are routed to your main mail log(s)
and more detailed entries routed to an Amavis-specific log file used to
feed the amavis-logwatch utility.
A convenient way to accomplish this is to change the Amavis configura-
tion variables in amavisd.conf as shown below:
amavisd.conf:
$log_level = 2;
$syslog_facility = 'local5';
$syslog_priority = 'debug';
This increases $log_level to 2, and sends Amavis' log entries to an
alternate syslog facility (eg. local5, user), which can then be routed
to one or more log files, including your main mail log file:
syslog.conf:
#mail.info -/var/log/maillog
mail.info;local5.notice -/var/log/maillog
local5.info -/var/log/amavisd-info.log
Amavis' typical $log_level 0 messages will be directed to both your
maillog and to the amavisd-info.log file, but higher $log_level mes-
sages will only be routed to the amavisd-info.log file. For additional
information on Amavis' logging, search the file RELEASE_NOTES in the
Amavis distribution for:
"syslog priorities are now dynamically derived"
ENVIRONMENT
The amavis-logwatch program uses the following (automatically set)
environment variables when running under Logwatch:
LOGWATCH_DETAIL_LEVEL
This is the detail level specified with the Logwatch command
line argument --detail or the Detail setting in the ...conf/ser-
vices/amavis.conf configuration file.
LOGWATCH_DEBUG
This is the debug level specified with the Logwatch command line
argument --debug.
amavis_xxx
The Logwatch program passes all settings amavis_xxx in the con-
figuration file ...conf/services/amavis.conf to the amavis fil-
ter (which is actually named .../scripts/services/amavis) via
environment variable.
