Counters.pl collects the CLI counters from network devices and produces custom reports. These counters can be reset independently of the SNMP counters, and when collected weekly, can highlight issues such as connection errors that you will not see looking at graphs produced from SNMP counters. They also contain information that is not available via SNMP. The reports can be viewed on a Web site and/or sent via email. There is a flexible configuration language in which reports can be specified. The format and style of the HTML reports are controlled by Template Toolkit templates and CSS. Currently only Cisco network equipment is supported.
Savepower is a simple and effective daemon for the cpufreq userspace governor. It is designed for workstations and servers, where all actions have to be done at the fastest speed, and after some idle time, maximum power savings are desired. It increases clock frequency to the maximum immediately on busy CPUs, and reduces the clock to the lowest frequency after a period of inactivity. The polling frequency is 1 second and can easily be shortened.
Splunk Hogs is a quick Perl script that was written to find what systems are sending too many events to Splunk and using up all the licenses. This is good for several reasons: developers will turn debugging on and use up all the licenses, which will help catch it early; INFO messages get turned on and useless events will be sent, filling up the licenses; issues will be detected that were being ignored by others. The advantage over Splunk's SaveSearch is that it outputs the raw data, so you can import it into Nagios or other tools. It collects raw data from Splunk that consists of the host, Splunk server, and the count of events that took place.
gitolite is an access control layer on top of git. It allows you to setup git hosting on a central server, and have multiple "virtual" users (i.e., not "Unix" users) access multiple git repositories, with fine grained access control (read control at the repo level granularity, write control at branch/tag/file/dir level). It has several other features, comprehensive documentation, does not require root permissions, and does not depend on anything except git, Perl 5.8 or later, and any POSIX shell.
AllWorldIT DBackup is a backup system which creates one archive per directory it backs up. This makes searching through the backup much easier, as you can look for which files you're after in the directory hierarchy. It will only back up directories which have changed, which makes it rsync friendly.
pgDynamicPartitions is a script that allows you to maintain a rolling window of daily table partitions under PostgreSQL. When called daily via cron, it will create x empty partitions into the future and keep only n partitions from the past 30 days, for example, and drop any that are older. It can be used with multiple tables, and each can be treated differently by calling it with different parameters via cron.
