Review of Paessler PRTG
And automatic detection of the host, from the place that provides a variety of monitoring format, without specializing in NetFlow, is a strong impression that the integrated monitoring and surveillance system.
Not open source (OSS), but work with free software are substantial.
I am thinking and function as a stand-alone NetFlowCollector diverges too much? However, since the installation and use can be started without a special knowledge in the free, the threshold of introduction is low.
In addition, since the Japanese support it is in fairly advanced, is considered likely to publish in-house members for.
