Nagios - Open Source Network Monitoring
Nagios is an Open Source solution to monitor complex IT infrastructures. Nagios can be used to perform alive checks to ensure the availability of networked systems. It is also possible to use Nagios for performance and capacity analyzes.
I write about Nagios cause I use it since several years. Over the time I collected much knowledge about Nagios and the surrounding projects. I contribute actively to the community writing and publishing plugins and maintaining the NagVis addon.
