Sawmill

A sawmill is a facility where logs are cut into lumber. Prior to the invention of the sawmill, boards were rived (split) and planed, or more often sawn by two men with a whipsaw, one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill, a Roman water-powered stone mill at Hierapolis, Asia Minor dating back to the 3rd century AD. Other water-powered mills followed and by the 11th century they were widespread in Islamic Spain and North Africa, the Middle East and Central Asia, and in the next few centuries, spread across Europe. The circular motion of the wheel was converted to a reciprocating motion at the saw blade. Generally, only the saw was powered, and the logs had to be loaded and moved by hand. An early improvement was the development of a movable carriage, also water powered, to move the log steadily through the saw blade.

By the time of the Industrial Revolution in the 18th century, the circular saw blade had been invented, and with the development of steam power in the 19th century, a much greater degree of mechanisation was possible. Scrap lumber from the mill provided a source of fuel for firing the boiler. The arrival of railroads meant that logs could be transported to mills rather than mills being built besides navigable waterways. By 1900, the largest sawmill in the world was operated by the Atlantic Lumber Company in Georgetown, South Carolina, using logs floated down the Pee Dee River from the Appalachian Mountains. In the 20th century the introduction of electricity and high technology furthered this process, and now most sawmills are massive and expensive facilities in which most aspects of the work is computerized. Besides the sawn timber, use is made of all the by-products including sawdust, bark, wood chips and wood pellets.

Sawmill (software)

Sawmill is a software package for the statistical analysis and reporting of log files, with dynamic contextual filtering, 'live' data zooming, user interface customization, and custom calculated reports. Sawmill also incorporates real-time reporting and real-time alerting. Available since 1997, at this time Sawmill provides support for approximately 850 server log file formats, with new formats added on request. Sawmill also includes a page tagging server and JavaScript page tag for the analysis of client side clicks (client requests) providing a total view of visitor traffic and on-site behavioural activity.

Sawmill Analytics is offered in three forms, as a software package for user deployment, as a turnkey on-premises system appliance, and as a SaaS. Sawmill analyzes any device or software package producing a log file and that includes web servers, firewalls, proxy servers, mail servers, network devices (switches & routers etc.), syslog servers, databases etc.

Sawmill is the OEM reporting engine sold by Blue Coat Systems as a bundled part of their proxy server product. A branded version of it is also sold by Cisco Systems as Sawmill for IronPort. A branded version of it is also sold by Vicomsoft Ltd as InterGate Intelligence. A branded version of it is also sold by SonicWALL as "SonicWALL Aventail Advanced Reporting".
