360-FAAR (Firewall Analysis Audit and Repair) is an offline, command line, Perl firewall policy manipulation tool to filter, compare to logs, merge, translate, and output firewall commands for new policies, in Checkpoint dbedit, Cisco ASA, or ScreenOS commands. It is all contained in one file. It can read policy and logs for: Checkpoint FW1 (in odumper.csv / logexport format), Netscreen ScreenOS (in get config / syslog format), and Cisco ASA (show run / syslog format). It uses both inclusive and exclusive CIDR and text filters, permitting you to split large policies into smaller ones for virutalization at the same time as removing unused connectivity. It supports policy to log association, object translation, rulebase reordering and simplification, rule moves, and duplicate matching automatically. It allows you to seamlessly move rules to where you need them. 'print' mode creates a spreadsheet for your audit needs with one command.
ColorLogs is an output-colorizing Perl script intended to have command output piped through it to a terminal. It allows easy creation of new highlighting configurations using simple text matches, globs, or regular expressions. It works transparently even in interactive contexts with scripts that produce prompt lines and wait for user input. Patterns are provided for Ant and Maven output. This version started as a fork of v1.1 from resentment.org, but numerous improvements have been made since then.
The Logfile Navigator, lnav for short, is a curses-based tool for viewing and analyzing log files. The value added by lnav over text viewers or editors is that it takes advantage of any semantic information that can be gleaned from the log file, such as timestamps and log levels. Using this extra semantic information, lnav can do things like interleaving messages from different files, generate histograms of messages over time, and provide hotkeys for navigating through the file. These features are meant to allow the user to quickly and efficiently focus on problems.
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).
