Sawmill has plug-ins to support the following log formats:


This plugin is designed to detect and analyze Media Flow Controller Access Logs that are recorded in the W3C Extended Log Format, first supported in MFC version 11.B.3. The W3C header record documents the log fields and their order in the log records. The information in the header record allows the W3C plug-in to parse and analyze any log file that conforms to the W3C standard regardless of the optional log fields and their order in the log records.

The W3C Log Format provides significant advantage over the NCSA log format supported by earlier versions of Media Flow Controller. Users can now choose to log any number of log fields in any order using a custom log profile. Sawmill can interpret these custom formats and generate reports for each individual log field. The Juniper Media Flow Controller NCSA plug-in can analyze 10 fields defined by the NCSA Common Log Format (CLF). The W3C plug-in can analyze 20 additional fields and the fields can be in any order as defined by the user using the log profile feature. The reports generated by this plug-in include:

  • Date and Time based reports such as daily, weekly, monthly & yearly reports of user traffic
  • Content analysis reports based on content popularity, server domain(s), server response status and content referrers
  • User demographic reports based on user's Country/State/City/Region, and ISP
  • Many other custom reports like Cacheable vs Non Cacheable Objects, Cache Control headers etc.

Sawmill is a Juniper Media Flow Controller (Access Logs) (W3C) log analyzer (it also supports the 1021 other log formats listed to the left). It can process log files in Juniper Media Flow Controller (Access Logs) (W3C) format, and generate dynamic statistics from them, analyzing and reporting events. Sawmill can parse Juniper Media Flow Controller (Access Logs) (W3C) logs, import them into a MySQL, Microsoft SQL Server, or Oracle database (or its own built-in database), aggregate them, and generate dynamically filtered reports, all through a web interface. Sawmill can perform Juniper Media Flow Controller (Access Logs) (W3C) log analysis on any platform, including Windows, Linux, FreeBSD, OpenBSD, Mac OS, Solaris, other UNIX, and others.

The database fields available in this log format are defined in the log data; Sawmill extracts the names and types of the fields from the log data, and tracks all available fields in its reports. Sawmill generates reports for each field, and allows dynamic filtering on any combination of these fields.

Sawmill stores the following numerical fields in its database for Juniper Media Flow Controller (Access Logs) (W3C), aggregating them and including them as columns in most reports:

Numerical Field  Internal Name
   accesses  accesses
   unique client IPs  unique_client_ips
   server-to-client bytes  sc_bytes
   client-to-server bytes  cs_bytes
