ADMLogger is a log analyzing engine. Using this core, users could easily build upon it with plugins. With very little Perl programming knowledge, it may become a powerful tool in a System Administrator's toolbox. ADMLogger creates email reports that can be formatted plain text or full HTML, which is up to the plugin designers to support. The main system has an HTML preference, so if your plugin ignores it, so be it. ADMLogger will also remove all filtered entries from the main syslog file into a second file so your other entries are more noticable.
Nmap Parser is a Perl module to ease the pain of developing scripts or collecting network information from nmap scans. Nmap::Parser does its task by parsing the information in the output of an nmap scan by using the XML-formatted output. This module can perform an nmap scan and parse the output automagically using parsescan(). It can parse an nmap XML file. This module was developed to speed up network security tool development when using nmap.
MRTG::Parse is a Perl extension that enables its users to parse and utilize the logfiles that are generated by the famous MRTG (Multi Router Traffic Grapher) tool. It's able to parse the total incoming and outgoing traffic of the current day, month, or year. Since version 0.03, it can also handle individual time periods to calculate the traffic that was generated between two dates.
IP::Country is a tool for fast lookup of country codes from IP addresses. Finding out the country of a client using only the IP address can be difficult. Looking up the domain name associated with that address can provide some help, but many IP address are not reverse mapped to any useful domain, and the most common domain (.com) offers no help when looking for country. This module comes bundled with a database of countries where various IP addresses have been assigned. Although the country of assignment will probably be the country associated with a large ISP rather than the client herself, this is probably good enough for most log analysis applications, and under test has proved to be as accurate as reverse-DNS and WHOIS lookup.
Zero RRD Framework provides a central HTTP-based service for importing into standard RRD databases and for generating graphs. A lightweight, easily extendable agent for the data sources pushes updates with minimal resource consumption to the master service using HTTP. With the introduction of VMs for the service, it's easy to test-drive the application and even the architecture (connecting agents to the service in the VM).
