Sawmill is a powerful hierarchical log analysis tool that runs on every major platform.


Sawmill is a UNIX Sendmail log analyzer (it also supports 827 other log formats). It can process log files in UNIX Sendmail format, and generate dynamic statistics from them, analyzing and reporting events. Sawmill can parse UNIX Sendmail logs, import them into a SQL database (or its own built-in database), aggregate them, and generate dynamically filtered reports, all through a web interface. Sawmill can perform UNIX Sendmail log analysis on any platform, including Window, Linux, FreeBSD, OpenBSD, Mac OS, Solaris, other UNIX, and others.

Sawmill stores the following non-numerical fields in its database for UNIX Sendmail, generates reports for each field, and allows dynamic filtering on any combination of these fields:

Field  Internal Name
   from  from
   to  to
   server  server
   daemon  daemon
   mailer  mailer
   status  stat
   class  class
   priority  pri
   protocol  proto
   relay  relay
   reject  reject

Sawmill stores the following numerical fields in its database for UNIX Sendmail, aggregating them and including them as columns in most reports:

Numerical Field  Internal Name
   messages  messages
   size  size
   delay  delay
   xdelay  xdelay
   number of recipients  nrcpts

Sawmill also supports 827 other log formats; see Sawmill Features for a list containing UNIX Sendmail and all the other supported formats.
