Zfswatcher is ZFS storage pool monitoring and notification daemon. It periodically inspects the zpool status and sends configurable notifications on status changes such as disk failures. It also controls the disk enclosure LEDs. There is an embedded Web interface for displaying status and logs.
Flawless traps exceptions and then uses git blame to send an email to the developer who wrote the buggy code. Even if a particular line of code causes thousands of exceptions, only one email will be sent. It uses git-blame to figure out which developer is responsible for a particular exception, and will only email that developer. If you set report_only_after_minimum_date, then Flawless will only report exceptions caused by code modified after report_only_after_minimum_date. You can mark certain files/functions as library code, and when an exception originates in those files/functions, the caller will be blamed for the error instead of the library code.

Nova is a software application for preventing and detecting hostile network reconnaissance (such as nmap scans). It does this by first creating the Haystack: a large collection of low interaction honeypots using an updated version of Honeyd. Finding real machines on the network becomes like finding a needle in a haystack of fake machines. Second, Nova uses machine learning algorithms to automatically detect and classify attempts at hostile reconnaissance, so there's no need to go searching manually through your honeypot's log files. It provides an easy to use Web-based interface powered by Node.js to configure itself and Honeyd instances.

FlatTraffic is a Web interface for analysing netflow records and showing statistics designed to make it clear and easy to determine which hosts on a network are consuming data. It has been primarily designed for use by networking and servers geeks who have to endure the pain of data-capped Internet Service Providers, something that's unfortunately rather common in the Australia/New Zealand region in particular.
