The Ninja project is an attempt to develop an alternative Nagios GUI with the aim of being the most useful Open Source Web front end for Nagios. It improves searching and filtering and scalability. It supports templates and skins for customizing appearance, and supports several databases. You can use the components of Ninja in combination with the CGI scripts of the original Nagios Web GUI or as replacements for them.
The Merlin project was initially started to create an easy way to set up distributed Nagios installations, allowing Nagios processes to exchange information directly as an alternative to the standard method using NSCA. It has also been extended with fault tolerance, the ability to store status information in a database, and other features. This allows Merlin to function as a backend for applications such as the Ninja project.
The drkhtb project was designed with medium to major Internet Service Providers in mind. Featuring extended hashing support, error handling, and simple configuration options, it has proven to be a stable solution for shaping up to 15000 residential clients with both upload and download rules, it is considered stable and is already in use as a production platform in at least one major ISP running 4 shaping bridges, each handling up to 2 Gbit/s, with a total of 48000 active clients and over 60000 filter rules in each direction. At this point there is no reason to believe that further bandwidth cannot be handled by one bridge, but there have not been sufficient resources to extensively test it. It is believed that up to 4 Gbit/s can be shaped on one individual machine serving at least 20000 clients.
Opsview Core is a network monitoring software application. It solves the challenges of monitoring modern IT and network systems. It is a drop-in replacement for Nagios Core, with full support for its plugins and 100% compatibility. It is easy to install and configure and is ideal for monitoring applications networks, and Windows, Linux, and Unix servers. VMWare, KVM, Xen, and Microsoft Hyper-V are supported, and Amazon EC2 and other cloud services can be monitored. It works with Opsview Mobile to allow you to monitor your systems on the go.
MyQoS Free Version is a bandwidth management solution based on FreeBSD 4.X. It provides all the necessary features for a small ISP to do QoS. It is limited to 2Mb/s unless you upgrade to the Standard Version. It is distributed as an appliance image. This image can be burnt to CD for testing before installation.
Panoptes is a scalable, extensible network and host monitoring tool. It includes a dynamic Web management interface based on the Dojo toolkit. It monitors SNMP, TCP port availability, ICMP, HTTP response and content, and SSL certificates internally. It supports monitoring anything else via shell scripts. It also includes a packet capture tool for discovery of hosts, port, and OS.
