ScanErrLog is a Python module that allows you to parse Apache error_log files and present their data in decreasing order of occurences of error messages. This is particularly useful if you want to quickly solve the most annoying problems Web visitors encounter on your site. You can use it directly from the command line, import it into another Python program and use the classes it defines, or use it as a CGI script. You can produce reports in HTML, PDF, XML, or Plain Text formats.
PushToTest TestMaker is a distributed test automation platform for application performance management and monitoring.

TestMaker is ideal for Web applications, Service Oriented Architecture (SOA) applications, Rich Internet Application (RIA using Ajax, Flex, Flash) and Business Process Management (BPM) applications.
TrafficWatch is a system for accounting Internet traffic in a residential college or school type of environment. It consists of a set of scripts and Web pages for accounting for each user's Internet usage by volume, and is currently capable of accounting for both Squid proxy traffic and direct IPv4 traffic.
PySquiLA is a Squid log analyzer. It was started due to frustration with existing tools that generate static pages and graphs while sometimes what you need is 'how my users used the proxy for the last 15 days'. The data of Squid's access.log is inserted into a MySQL database. This database is used by the CGI part of PySquiLA to generate on-the-fly graphs and tables, with a great degree of liberty in choosing how, when, and what you need to know.
