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.
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.
