NAME

qmail2dlf - convert sanitized qmail-send logs to dlf

SYNOPSIS

qmail2ldf

DESCRIPTION

qmail2dlf reads qmail-send logs from stdin, writes dlf to stdout, and, in case of errors, complains on stderr.

TIMESTAMPS

We expect timestamps which look like e.g. `977359048.466280500' in our log: number of seconds since the epoch, in any precision. The log should feature lines which look something like:
  982584201.511524 info msg 6426: bytes 3537 from 
    <qmail-return-63074-joostvb=mdcc.cx@list.cr.yp.to> qp 21089 uid 70
 
 

splogger, as distributed with qmail, writes `a numerical timestamp', ie something like 972802273.627578, indicating seconds and nanoseconds since the beginning of 1970.

multilog, as distributed with daemontools, http://cr.yp.to/daemontools.html, if invoked with action t, writes a `@' and a tai64n format timestamp. These timestamps look like e.g. 4000000039ef8532346bb35c. Note that 0x400000000000000000000000 is 2^62.

One can get the current time in tai64 format by doing:

  echo 40000000`(echo obase = 16; date +%s) | bc`00000000
 
 

(assuming GNU date is installed)

To convert tai64n to numerical timestamps, one can use Russ Allbery's tai64nfraq. It's in the public domain, available from http://www.qmail.org/tai64nfrac.

EXAMPLE

To process a log as produced by splogger:
  $ lr_desyslog qmail < mail.log | qmail2dlf
 
 

To process a log as produced by multilog:

  $ tai64nfrac < current | qmail2dlf
 
 

qmail2dlf(1) will be rarely used on its own, but is more likely called by lr_log2report:

  $ tai64nfrac < /service/qmail-send/log/main/current | \
      lr_log2report qmail
 
 

BUGS

We don't deal with bounces:
  email qmail none qmail2dlf info skipping line '986244190.800217 bounce msg 
   6306 qp 28445': first field should be one of 'new', 'info', 'starting', 
   'delivery', 'end' or 'status:', not 'bounce'
 
 

qmail2dlf doesn't use any information from the qmail-smtpd(1) logs. (These look like

  2002-06-16 09:34:57.798038500 tcpserver: pid 19385 from 100.61.24.7
  2002-06-16 09:34:58.114198500 tcpserver: ok 19385 foo.example.com:100.163.25.11:25 logreport.iae.nl:212.61.24.7:postfix:1189
