Advanced Web Statistics (AWStats) is a free powerful Web server logfile analyzer (Perl script) that shows you all your Web statistics including visits, unique visitors, pages, hits, rush hours, search engines, keywords used to find your site, robots, broken links, and more. It works with both IIS 5.0+ and Apache Web server log files as a CGI and/or from the command line. It also supports around 40 languages.
Performance Co-Pilot (PCP) is a framework and set of services for supporting system-level performance monitoring and performance management. It provides a unifying abstraction for all of the interesting performance data in a system, and allows client applications to easily retrieve and process any subset of that data using a single API. A client-server architecture allows multiple clients to monitor the same host, and a single client to monitor multiple hosts. Archive logging and replay are integrated so that a client application can use the same API to process real-time data from a host or historical data from an archive.
log_analysis is a log file analysis engine that extracts relevant data for any of the recognised log messages and produces a summary that is much easier to read. It can be configured to recognize entirely new log types. log_analysis natively understands about 100 different kinds of syslog messages, as well as sulog and wtmp messages for Linux, Solaris, and OpenBSD. It also has optional continuous monitoring capabilities, with both text and GUI modes.
SiLK (System for Internet-Level Knowledge) consists of two sets of tools: a packing system and an analysis suite. The packing system receives Netflow V5 PDUs or IPFIX and converts them into a more space efficient format, recording the packed records into service-specific binary flat files. The analysis suite consists of tools that can read these flat files and then perform various query operations, ranging from per-record filtering to statistical analysis of groups of records. The analysis tools interoperate using pipes, allowing a user to develop a relatively sophisticated query from a simple beginning.
DenyThem is a program designed to protect your Linux system from malicious attacks. It is an active response system to disrupt and block dictionary attacks and DOS attacks. DenyThem by default uses /var/log/syslog and /var/log/auth.log and searches for hack attempts. When DenyThem finds enough hack attempts from a single host, it will add a DROP statement to your system's firewall, thus preventing future attacks. DenyThem uses iptables, so it will only work on Linux or any other system that uses iptables. It can also block traffic from specific countries.
user_info is a class to retrieve information about the browser the user is using to access the current site script. It can analyze the user agent string sent by the browser in the current HTTP request and extracts the type of browser, user machine operating system, user machine IP address, accepted character set encoding, language name, and whether the user is a spider/bot.
Wiresoft ANA (Automated Network Agent), an Artificial Intelligence-based systems management service, automatically performs over 90% of Linux systems management tasks. It is a self-managing, self-learning system support service that provides constant maintenance and protection for Firegate Servers. ANA services include Software Updating and Integration, Intrusion Detection, Data Back-up and Disaster Recovery, Monitoring, and Alerting.
