Zabbix

 Zabbix is a network management system application created by Alexei Vladishev. It is designed to monitor and track the status of various network services, servers, and other network hardware. It uses MySQL, PostgreSQL, SQLite or Oracle to store data. Its web based frontend is written in PHP. ZABBIX offers several monitoring options. Simple checks can verify the availability and responsiveness of standard services such as SMTP or HTTP without installing any software on the monitored host. A ZABBIX agent can also be installed on UNIX and Windows hosts to monitor statistics such as CPU load, network utilization, disk space, etc. As an alternative to installing an agent on hosts, ZABBIX includes support for monitoring via SNMP.

OpenNMS

 OpenNMS is an enterprise grade network monitoring platform developed under the open source model. It consists of a community supported open-source project as well as a commercial services, training and support organization. The goal is for OpenNMS to be a truly distributed, scalable platform for all aspects of the FCAPS network management model, and to make this platform available to both open source and commercial applications.

Ganglia

 Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on thousands of clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes.

Nagios

 Nagios is a host and service monitor designed to inform you of network problems before your clients, end-users or managers do. It has been designed to run under the Linux operating system, but works fine under most *NIX variants as well. The monitoring daemon runs intermittent checks on hosts and services you specify using external "plugins" which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.). Current status information, historical logs, and reports can all be accessed via a web browser.

Hyperic

 Hyperic is an advanced monitoring tool for monitoring systems, networks, disk space and many other things. It has an advanced UI and very nice reporting capabilities.
