Switchmap is a Perl program that creates HTML pages that show information about a set of Cisco Ethernet switches. It uses SNMP to gather data from a list of switches, given the list of IP addresses and names. The output pages show, for each port, the status, duplex, VLAN, speed, and what's connected to the port (MAC address, IP address, DNS name). The pages help network engineers quickly see switch information.
LiKee (which stands for LIne KEEper) is a monitoring system for supervision of Web applications and pages. It is a tool for automation of service processes of uptime-critical Web applications. It periodically monitors remote pages and evaluates their content with regular expressions. It can send alerts through email, GSM calls, and SMS. It offers Web-based administration and reporting with advanced graphical design.

Gossimon is a gossip-based distributed monitoring system for a cluster of Linux nodes. Each node in the cluster periodically send information about itself and others to a randomly selected node. This way, each node constantly receives information about cluster nodes. This information is locally maintained (constantly updated) by each node and can be used by various clients for monitoring and resource allocation. The gossip protocols used by gossimon are very robust to node failure, and the information quality is hardly degraded even when large parts of the cluster are taken down. The package contains: infod (the daemon responsible for collecting and sending information for other nodes); mmon (a curses-based monitoring client displaying information about cluster nodes); and infod-client (a command-line client that retrieves cluster information in XML format).
Postbix is a plugin designed to work with Zabbix Enterprise Monitor to provide multi-tiered monitoring and performance and availability reporting and measurement for PostgreSQL databases, along with server performance metrics. It provides an effective mechanism to acquire data from numerous PostgreSQL instances, and in turn provides this information for monitoring and performance metrics to your Zabbix server. You can then utilise the reporting capabilities of Zabbix for all data collected, and provide analysis such as graphs and service-level agreement metrics for stakeholders. The current distribution contains a set of pre-defined templates that incorporate alerting and graphing capabilities from initial deployment. However, these can be fine tuned to suit your needs and data/monitoring requirements.
