Advisory Check is a program that reads security advisories for you. It gathers security advisories using RSS, RDF, or XML feeds, compares them against the installed software, and alerts you if you're vulnerable. A wide variety of package managers can be queried to detect installed software. Remote systems can be monitored by using the integrated SSH, Windows-RPC, and Nmap support.
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.
BigDaddy is a program for monitoring servers. It is similar to Nagios, with the added benefit of also monitoring and controlling the crontab (or any scheduled application) across an entire fleet of servers. The application comes in the form of a daemon for monitoring and reporting as well as an easy-to-use Web-based GUI for controlling monitoring, viewing timelines of incidents, filing incidents and graphing statistics. The application is extensible with any sort of monitoring module and notification is based on a five step escalation process.
Blogbench is a portable filesystem benchmark that tries to reproduce the load of a real-world busy file server. It stresses the filesystem with multiple threads performing random reads, writes, and rewrites in order to get a realistic idea of the scalability and the concurrency a system can handle.
BulkWatch is a utility that monitors sendmail's logs and takes a specified action when an IP has exceeded your configured maximum settings. You can specify that users may send X messages in X number of seconds. Email in excess of that would trigger an action, which can be any of the following: display an alert to the screen in foreground mode; log an alert to syslog; email an alert to a predefined email address; or run an external command with the IP and number of messages as arguments.
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.
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.
