It can recursively hash files on disk, either outputing hashes to stdout, or storing them in filesystem attributes, or in a memcached server. It can check files against a list of hashes supplied on stdin, or in t
NetHogs is a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth. Since NetHogs heavily relies on /proc, most features are only a
OpenAPC is an APC (Advanced Process Control) solution that is highly flexible and configurable and covers a wide range of automation, visualization, and process control tasks from home control up to industrial automation and manufacturing.

wmsorsen is a dockapp which displays hardware sensor values.
watcher.js is a Node.js/Express/AngularJS based application that can be used to monitor service status. At regular intervals service specific defined messages, either as http requests or as raw data to sockets, are send to the service endpoints to find out their status. On the service status resolution, the status is stored internally and is made available either programmatically or via REST requests. The application, at design level, is extensible since custom defined behaviors can be easily ap
downtimed is a program that monitors operating system downtime, uptime, shutdowns, and crashes and records such events. At OS startup it logs information about previous downtime. It then periodically updates a time stamp file on the disk, which is used to determine the approximate time when the system was last up and running. During a graceful system shutdown, it records a time stamp in another file. The downtimes(1) command line tool can be used to inspect records of past downtime.
SSHGuard is an automated log watcher which quickly sets up firewall blocks for detected brute-force attacks. It supports not just SSH, but also sendmail, exim, dovecot, Cucipop, UWimap, vsftpd, proftpd, pure-ftpd and FreeBSD ftpd. It understands syslog/-ng, metalog, multilog and raw log formats. And works with netfilter/iptables, PF, ipfw, or just hosts.allow to set up firewalling rules.
NetDB can inventarize and historize MAC address allocation on network switches and ARP tables on routers. It stores those using MySQL. It supports extensive switch, VLAN and vendor code reports, or tracks static IP addresses, and record neighbor discover. It provides a CLI interface and a web interface, or generate CSV lists.
checkraid is a script that uses OEM tools to check the status of RAID arrays. It can be used standalone, with snmpd or nagios nrpe. The script is nagios/icinga compatible. It currently works with Adaptec (arcconf), 3ware (tw_cli), zfs (zpool), and md (mdadm).
Apache GUI provides a web-based management interface for the Apache HTTP server, implemented in Java and works on Linux and MacOS or Windows setups.

NodeBrain is a rule engine for construction of state and event monitoring applications. It interacts with other monitoring components to perform simple element state monitoring or complex event correlation based on user specified rules. It is extended through the development of node modules (plug-ins) using NodeBrain's C API, and servants (programs written in any language) that interact with the rule engine via stdin, stdout, and stderr. The package includes a small set of plug-in modules to pro
