Alerttail monitors a given file and executes a list of actions when a user-defined text pattern has been written to the file. For example, the user can pop up a GTK notification window when a certain message is written to a log file. Actions can be alerttail built in actions (GTK notify action, geoipLocalization action, or filtering text action) or a custom user defined shell command action. A Qt 4 GUI frontend helps with configuration.
Bartlby is a network and system monitor, completely written in C, to provide a scalable framework with the ability to monitor networks of various sizes. It consists of a core daemon, several plugins, and a Web GUI (PHP extension). The core daemon checks (over active/passive TCP) services/hosts and notifies users in case of critical service conditions (mail, SMS, ICQ, and custom triggers are supported). Bartlby provides an open plugin interface to give every administrator an easy to use option to extend the plugin base, and a fully customizable GUI (written in PHP using a C extension). Nearby everything can be controlled via an XML interface.
CD-ROM Digest is a program that checks a multi-track CD-ROM. It reports the MD5 digest and size for each track on a CD-ROM. The digest is done as the track is read, without dumping CD-ROM data on the hard drive. This tool helps users that are burning a multi-track CD-ROM to check the result.
CleverEye is an affordable availability monitoring suite for fundamental monitoring and reporting on network components, Web sites, databases, crucial user tasks, system health, and application transaction response times. It provides flexible, ready-made reports on real-time and historical system data for finding bottlenecks. Features include alerting, trend analysis, auto discovery, user management, network status map, SLA monitoring, and business level views.
Daemonzup is a server monitoring tool that will check if several services/daemons are up on a specific server. It is run from a cron job. If a daemon appears to be dead, it will send email to admins, plus it may also try to restart it. It is designed for GNU/Linux and depends on Perl. It can monitor whatever software is daemonized: apache, MySQL, SSH, cron, xinet, syslog, etc.
Diskus is a high-level hard drive diagnostic and limited repair tool. It checks the disk geometry by writing numbered IDs into the sectors of the hard drive. Later one can verify that these sector-IDs on the disk are still correct, thereby detecting data which was not correctly written. There is an option to "freshen" the data on your harddrive, which will read and rewrite the sectors. With modern drives this will re-map defective sectors.
FTPL (FakeTime Preload Library, aka libfaketime) intercepts various system library calls and tricks programs of your choice into seeing a faked system time without having to change the time system-wide. This can be used for running legacy software with Y2K bugs, testing software for year-2038 compliance, debugging time-related issues such as expired SSL certificates, and using software that ceases to run outside a certain time frame. The faked time can be specified either absolutely or relative to the real current time, and optionally also affects file timestamps. The faked clock continues to run, but can optionally be frozen, slowed down, or made faster. A wrapper script "faketime" simplifies the usage, similar to tools such as fakechroot.
