SyslogScan::SendmailLine -- Enhances basic SyslogEntry parsing by understanding sendmail to/from message syntax.
Suppose I run a 'new SyslogEntry' command and read in the following line:
Jun 13 01:32:26 satellife sendmail: WAA18677: email@example.com,firstname.lastname@example.org, delay=03:50:20, mailer=smtp, relay=relay.ulthar.com [18.104.22.168], stat=Sent (May, have (embedded, commas))
If I have not loaded in SendmailLine, then 'new SyslogEntry' will return an 'UnsupportedEntry' object looking like this:
month => Jun, day => 13, time => 01:32:26, machine => satellife, executable => sendmail, tag => 23498, content => WAA18677: email@example.com,firstname.lastname@example.org, delay=03:50:20, ...
On the other hand, if I have a 'use SyslogScan::SendmailLine' command before my call to 'new SyslogEntry', then I will a 'SendmailLine' object with all of the above parameters, plus the following additional parameters:
messageID => WAA18677 toList => ( email@example.com, firstname.lastname@example.org ) attrHash => ( to => "email@example.com,firstname.lastname@example.org", delay => "03:50:20", mailer => "smtp", relay => "relay.ulthar.com [22.214.171.124]", stat => "Sent (May, have (embedded, commas))" )
Also well-supported is the 'From' line:
Jun 13 01:34:54 satellife sendmail: BAA26035: from=<bar!baz!foo>, size=7000, class=0, pri=37000, nrcpts=1, msgid=<199606130634.BAA26035@satellife.healthnet.org>, proto=SMTP, relay=uth.bar.com [126.96.36.199]
will produce a SendmailLine object with the additional attributes of
messageID => BAA26035 attrHash => ( from => "<bar!baz!foo>", size => "7000", class => "0", pri => "37000" nrcpts => "1", msgid => "<199606130634.BAA26035@satellife.healthnet.org>", proto => "SMTP", relay => "uth.bar.com [188.8.131.52]" )
Other types of lines are legal, but are not currently very thorougly parsed, and therefore return somewhat minimal SendmailLine objects.
Jun 13 13:05:35 satellife sendmail: NAA19606: NAA19620: return to sender: unknown mailer error 2
will return a SendmailLine object with the usual SyslogEntry attributes, plus the single additional attribute of
messageID => NAA19606
while lines like the following produce SendmailLine objects with no additional SendmailLine-specific attributes:
Jun 13 03:00:05 satellife sendmail: alias database /var/yp/nis.healthnet.org/mail.aliases rebuilt by root
Note this is a subclass for SyslogScan::SyslogEntry which handles certain types of logfile lines. See the documentation for SyslogEntry for further details of how SyslogEntry subclassing works.
Also, see the SyslogScan::SendmailLineFrom and SyslogScan::SendmailLineTo modules for examples of returned SendmailLine objects.
