AMAVIS-LOGWATCH(1)	    General Commands Manual	    AMAVIS-LOGWATCH(1)

       amavis-logwatch - An Amavisd-new	log parser and analysis	utility

       amavis-logwatch [options] [logfile ...]

       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-

       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:

	   ****** Detailed *******************************************

		 12	       <>

       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.

       The options listed below	affect the operation of	amavis-logwatch.   Op-
       tions  specified	 later on the command line override earlier ones.  Any
       option may be abbreviated to an unambiguous length.

       --show_autolearn	boolean
	      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".

       --show_by_ccat_summary boolean
	      Enables  (disables) the by contents category summary in the Sum-
	      mary section.  Default: enabled.

       -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 de-
	      scribed below.

	      The amavis-logwatch utility produces a Summary  section,	a  De-
	      tailed section, and additional report sections.  With level less
	      than 5, amavis-logwatch will produce only	the  Summary  section.
	      At  level	 5 and above, the Detailed section, and	any additional
	      report sections are candidates for output.  Each incremental in-
	      crease  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).

       --show_first_recip_only boolean
	      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 de-
	      fault), long  lines  will	 be  truncated	according  to  max_re-
	      port_width.   Setting  style to wrap will	wrap lines longer than
	      max_report_width such that left column hit counts	 are  not  ob-
	      scured.	This  option  takes precedence over the	line style im-
	      plied by the detail level.  The options --full, --truncate,  and
	      --wrap are synonyms.

	      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  de-
	      fault values.

	      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 re-
	      port.  The arguments P1 ... are integers from 0  to  100	inclu-
	      sive.  Their order will be preserved in the report.

	      Disables the SpamAssassin	Timings	report.

	      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 de-
	      fault uses the built-in default values.

	      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.

	      Disables the Spam	Score Percentiles report.

       --show_sect_vars	boolean
	      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.

       --show_startinfo	boolean
	      Enables (disables) the Amavis startup report showing most	recent
	      Amavis startup details.


	      Enables (disables) displaying of the the Summary section of  the
	      report.	The variable Amavis_Show_Summary in used in a configu-
	      ration file.

       --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.

	      Disables the Amavis Scan Timings report.

	      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

       The list	of level limiters is shown below.

       Amavis major contents category (ccatmajor) sections, listed in order of

	      Blocked or passed	 messages  that	 contain  malware  (ccatmajor:

       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-

	   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 un-
       til detail is at	least 5).

       See the EXAMPLES	section	for usage scenarios.

       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 in-

       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 oc-
       curs as follows:	1) The default configuration file is read if it	exists
       and no --config_file was	specified on a command line.  2) Configuration
       files  are  read	 and processed in the order found on the command 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.

       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.

   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

	   19346   Spam	blocked	-----------------------------------
	      12	    <>
	      12	    <>
	       8	    <>
	       8	    <>
	       8	    <>
	       7	    <>
	       8	    <>
	       7	    <>

   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  re-
       ports  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  De-
       tailed 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-

       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:

	       $log_level = 2;
	       $syslog_facility	= 'local5';
	       $syslog_priority	= 'debug';

       This increases $log_level to 2, and sends Amavis' log entries to	an al-
       ternate syslog facility (eg. local5, user), which can then be routed to
       one or more log files, including	your main mail log file:

	   syslog.conf:			  -/var/log/maillog;local5.notice		  -/var/log/maillog			  -/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"

       The  amavis-logwatch program uses the following (automatically set) en-
       vironment variables when	running	under Logwatch:

	      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.

	      This is the debug	level specified	with the Logwatch command line
	      argument --debug.

	      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.
