Swatch was originally written to actively monitor messages as they were written to a log file via the UNIX syslog utility. It has multiple methods of alarming, both visually and by triggering events. The perfect tools for a master loghost. It is known to work flawlessly on Linux (RH5), BSDI, and Solaris 2.6 (patched).
For a system administrator it is a bothersome job to sort out the interesting (and sometimes alarming) log entries from the pile of standard entries. Tidy distinguishes different services (telnet, finger, etc.) and removes standard entries. Furthermore tidy tries to extract a remote host from the messages. These remote hosts are added to a statistics database. The number of contacts of each service is saved together with the time/date stamp of the last contact. The statistics can be printed out as simple ASCII or HTML.
User-Agent Log Watch (ULW) processes custom Apache logs and reports hits based on combinations of URL, user agent, and remote IP address. It maintains a list of known IPs, so they aren't reported twice. The list of URL/UA/IP is stored in a configuration file, and its entries can be regexp-understood by gawk. It can be cronned or it can call mail/sendmail. The custom log is reset each time ULW is invoked and processed logs are gzipped and stored in a different location.
The objective of the NIST Web Metrics Testbed is to explore the feasibility of a range of tools and techniques that support rapid, remote, and automated testing and evaluation of website usability. There are currently six components: 1. Web Static Analyzer Tool (WebSAT): checks web page HTML against typical usability guidelines. 2. Web Category Analysis Tool (WebCAT): lets the usability engineer construct and conduct a web category analysis (card-sorting). 3. Web Variable Instrumenter Program (WebVIP): instruments a website to capture a log of user interaction. 4. Framework for Logging Usability Data (FLUD): a file format and parser for representation of user interaction logs (such as those captured by WebVIP). 5. VisVIP Tool: produces a 3D visualization of user navigation paths through a website, based on FLUD data. 6. TreeDec: adds navigation aids to the pages of a website.
