check_aaccli is a plugin for Nagios which checks the hardware health of Adaptec SCSI RAID controllers. To accomplish this, you must have installed the aaccli binary (from the aacapps package). The plugin checks the error log of single disks (with S.M.A.R.T.) and the health of mirror containers.
net-status-monitor is a simple console script to test whether Internet connectivity is working. If it is, the script tells you the external IP address (in case your dynamic DNS provider is down). If not, it tries to find the point where the connectivity fails. The output is quite simple, so you can put it on your grandmother's PC. "Just tell me what the read line says" should give you enough information.
mod_top is a production monitoring tool for LAMP applications with user interfaces modeled after the popular Unix top. It plans to support PHP, Perl, Ruby, Python, mySQL, PostgreSQL, and Apache 1 and 2 on Linux. It can help you locate bottlenecks in applications, troubleshoot high memory consumption, understand CPU utilization under load, diagnose causes of slowness or heavy resource utilization, or discover database dependencies.
Fritz!WRT is a set of patches to make the OpenWRT trunk run on AVMs Fritz!Box. Much progress has been made in recent OpenWRT revisions in the AR7 port, but it's still not running on the Fritz!Box. The patches also have the potential to make the T-Com SpeedPort run, because its hardware is very similar to that of the Fritz!Box. There are patches for the bootloader, LED support, and watchdog support, as well as KGDB support.
weedit is a file duplicate scanner with database support. It uses CRC32, MD5, and file size to scan for duplicates. Files that are deleted are automatically removed from the database when a duplicate is found. It will only rescan files if the creation time or last write time change. It will only delete duplicated files if the parameter for deleting is used. The default setting is to report only.
check_hpasm is a plugin for Nagios which checks the hardware health of Hewlett-Packard Proliant servers. To accomplish this, you must have installed the hpasm package. The plugin checks the health of processors, power supplies, memory modules, fans, CPU- and board-temperatures, and alerts you if one of these components is faulty or operates outside its normal parameters.
GLBOX is a lightweight version of a sandbox. It monitors the execution of any program, regardless of the programing language in which it was written or the accessibility to source code. Since all processes access operating system resources via system calls, controlling those calls is the most general way to monitor a program's behavior.
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.
