pflogsumm.pl -[help|version]
If no file(s) specified, reads from stdin. Output is to stdout.
=head1 DESCRIPTION
Pflogsumm is a log analyzer/summarizer for the Postfix MTA. It is
designed to provide an over-view of Postfix activity, with just enough
detail to give the administrator a "heads up" for potential trouble
spots.
Pflogsumm generates summaries and, in some cases, detailed reports of
mail server traffic volumes, rejected and bounced email, and server
warnings, errors and panics.
=head1 OPTIONS
--bounce-detail <cnt>
Limit detailed bounce reports to the top <cnt>. 0
to suppress entirely.
-d today generate report for just today
-d yesterday generate report for just "yesterday"
--deferral-detail <cnt>
Limit detailed deferral reports to the top <cnt>. 0
to suppress entirely.
--detail <cnt>
Sets all --*-detail, -h and -u to <cnt>. Is
over-ridden by individual settings. --detail 0
suppresses *all* detail.
-e extended (extreme? excessive?) detail
Emit detailed reports. At present, this includes
only a per-message report, sorted by sender domain,
then user-in-domain, then by queue i.d.
WARNING: the data built to generate this report can
quickly consume very large amounts of memory if a
lot of log entries are processed!
-h <cnt> top <cnt> to display in host/domain reports.
0 = none.
See also: "-u" and "--*-detail" options for further
report-limiting options.
--help Emit short usage message and bail out.
(By happy coincidence, "-h" alone does much the same,
being as it requires a numeric argument :-). Yeah, I
know: lame.)
-i
--ignore-case Handle complete email address in a case-insensitive
manner.
Normally pflogsumm lower-cases only the host and
domain parts, leaving the user part alone. This
option causes the entire email address to be lower-
cased.
--iso-date-time
For summaries that contain date or time information,
use ISO 8601 standard formats (CCYY-MM-DD and HH:MM),
rather than "Mon DD CCYY" and "HHMM".
-m modify (mung?) UUCP-style bang-paths
--uucp-mung
This is for use when you have a mix of Internet-style
domain addresses and UUCP-style bang-paths in the log.
Upstream UUCP feeds sometimes mung Internet domain
style address into bang-paths. This option can
sometimes undo the "damage". For example:
"somehost.dom!username@foo" (where "foo" is the next
host upstream and "somehost.dom" was whence the email
originated) will get converted to
"foo!username@somehost.dom". This also affects the
extended detail report (-e), to help ensure that by-
domain-by-name sorting is more accurate.
--mailq Run "mailq" command at end of report.
Merely a convenience feature. (Assumes that "mailq"
is in $PATH. See "$mailqCmd" variable to path thisi
if desired.)
--no_bounce_detail
--no_deferral_detail
--no_reject_detail
These switches are deprecated in favour of
--bounce-detail, --deferral-detail and
--reject-detail, respectively.
Suppresses the printing of the following detailed
reports, respectively:
message bounce detail (by relay)
message deferral detail
message reject detail
See also: "-u" and "-h" for further report-limiting
options.
--no-no-msg-size
Do not emit report on "Messages with no size data".
Message size is reported only by the queue manager.
The message may be delivered long-enough after the
(last) qmgr log entry that the information is not in
the log(s) processed by a particular run of
pflogsumm.pl. This throws off "Recipients by message
size" and the total for "bytes delivered." These are
normally reported by pflogsumm as "Messages with no
size data."
--no-smtpd-warnings
This switch is deprecated in favour of
smtpd-warning-detail
On a busy mail server, say at an ISP, SMTPD warnings
can result in a rather sizeable report. This option
turns reporting them off.
--problems-first
Emit "problems" reports (bounces, defers, warnings,
etc.) before "normal" stats.
--rej-add-from
For those reject reports that list IP addresses or
host/domain names: append the email from address to
each listing. (Does not apply to "Improper use of
SMTP command pipelining" report.)
-q quiet - don't print headings for empty reports
note: headings for warning, fatal, and "master"
messages will always be printed.
--reject-detail <cnt>
Limit detailed smtpd reject, warn, hold and discard
reports to the top <cnt>. 0 to suppress entirely.
--smtp-detail <cnt>
Limit detailed smtp delivery reports to the top <cnt>.
0 to suppress entirely.
--smtpd-stats
Generate smtpd connection statistics.
The "per-day" report is not generated for single-day
reports. For multiple-day reports: "per-hour" numbers
are daily averages (reflected in the report heading).
--smtpd-warning-detail <cnt>
Limit detailed smtpd warnings reports to the top <cnt>.
0 to suppress entirely.
--syslog-name=name
Set syslog-name to look for for Postfix log entries.
By default, pflogsumm looks for entries in logfiles
with a syslog name of "postfix," the default.
If you've set a non-default "syslog_name" parameter
in your Postfix configuration, use this option to
tell pflogsumm what that is.
See the discussion about the use of this option under
"NOTES," below.
-u <cnt> top <cnt> to display in user reports. 0 == none.
See also: "-h" and "--*-detail" options for further
report-limiting options.
--verbose-msg-detail
For the message deferral, bounce and reject summaries:
display the full "reason", rather than a truncated one.
Note: this can result in quite long lines in the report.
--verp-mung do "VERP" generated address (?) munging. Convert
--verp-mung=2 sender addresses of the form
"list-return-NN-someuser=some.dom@host.sender.dom"
to
"list-return-ID-someuser=some.dom@host.sender.dom"
In other words: replace the numeric value with "ID".
By specifying the optional "=2" (second form), the
munging is more "aggressive", converting the address
to something like:
"list-return@host.sender.dom"
Actually: specifying anything less than 2 does the
"simple" munging and anything greater than 1 results
in the more "aggressive" hack being applied.
See "NOTES" regarding this option.
--version Print program name and version and bail out.
--zero-fill "Zero-fill" certain arrays so reports come out with
data in columns that that might otherwise be blank.
=head1 RETURN VALUE
Pflogsumm doesn't return anything of interest to the shell.
=head1 ERRORS
Error messages are emitted to stderr.
=head1 EXAMPLES
Produce a report of previous day's activities:
pflogsumm.pl -d yesterday /var/log/maillog
A report of prior week's activities (after logs rotated):
pflogsumm.pl /var/log/maillog.0
What's happened so far today:
pflogsumm.pl -d today /var/log/maillog
Crontab entry to generate a report of the previous day's activity
at 10 minutes after midnight.
10 0 * * * /usr/local/sbin/pflogsumm -d yesterday /var/log/maillog
2>&1 |/usr/bin/mailx -s "`uname -n` daily mail stats" postmaster
Crontab entry to generate a report for the prior week's activity.
(This example assumes one rotates ones mail logs weekly, some time
before 4:10 a.m. on Sunday.)
10 4 * * 0 /usr/local/sbin/pflogsumm /var/log/maillog.0
2>&1 |/usr/bin/mailx -s "`uname -n` weekly mail stats" postmaster
The two crontab examples, above, must actually be a single line
each. They're broken-up into two-or-more lines due to page
formatting issues.
=head1 SEE ALSO
The pflogsumm FAQ: pflogsumm-faq.txt.
=head1 NOTES
Pflogsumm makes no attempt to catch/parse non-Postfix log
entries. Unless it has "postfix/" in the log entry, it will be
ignored.
It's important that the logs are presented to pflogsumm in
chronological order so that message sizes are available when
needed.
For display purposes: integer values are munged into "kilo" and
"mega" notation as they exceed certain values. I chose the
admittedly arbitrary boundaries of 512k and 512m as the points at
which to do this--my thinking being 512x was the largest number
(of digits) that most folks can comfortably grok at-a-glance.
These are "computer" "k" and "m", not 1000 and 1,000,000. You
can easily change all of this with some constants near the
beginning of the program.
"Items-per-day" reports are not generated for single-day
reports. For multiple-day reports: "Items-per-hour" numbers are
daily averages (reflected in the report headings).
Message rejects, reject warnings, holds and discards are all
reported under the "rejects" column for the Per-Hour and Per-Day
traffic summaries.
Verp munging may not always result in correct address and
address-count reduction.
Verp munging is always in a state of experimentation. The use
of this option may result in inaccurate statistics with regards
to the "senders" count.
UUCP-style bang-path handling needs more work. Particularly if
Postfix is not being run with "swap_bangpath = yes" and/or *is* being
run with "append_dot_mydomain = yes", the detailed by-message report
may not be sorted correctly by-domain-by-user. (Also depends on
upstream MTA, I suspect.)
The "percent rejected" and "percent discarded" figures are only
approximations. They are calculated as follows (example is for
"percent rejected"):
percent rejected =
(rejected / (delivered + rejected + discarded)) * 100
There are some issues with the use of --syslog-name. The problem is
that, even with Postfix' $syslog_name set, it will sometimes still
log things with "postfix" as the syslog_name. This is noted in
/etc/postfix/sample-misc.cf:
# Beware: a non-default syslog_name setting takes effect only
# after process initialization. Some initialization errors will be
# logged with the default name, especially errors while parsing
# the command line and errors while accessing the Postfix main.cf
# configuration file.
As a consequence, pflogsumm must always look for "postfix," in logs,
as well as whatever is supplied for syslog_name.
Where this becomes an issue is where people are running two or more
instances of Postfix, logging to the same file. In such a case:
. Neither instance may use the default "postfix" syslog name
and...
. Log entries that fall victim to what's described in
sample-misc.cf will be reported under "postfix", so that if
you're running pflogsumm twice, once for each syslog_name, such
log entries will show up in each report.

=head1 REQUIREMENTS
For certain options (e.g.: --smtpd-stats), Pflogsumm requires the
Date::Calc module, which can be obtained from CPAN at
http://www.perl.com.
Pflogsumm is currently written and tested under Perl 5.8.3.
As of version 19990413-02, pflogsumm worked with Perl 5.003, but
future compatibility is not guaranteed.
