Darkstat is another built-in capture function in Netrounds. It uses the open source software available at unix4lyfe.org/darkstat/.
Darkstat captures network traffic on the Test Agent interface "eth1", calculates statistics on usage, and publishes reports over HTTP. Its features include traffic graphs, reports per host, showing of ports for each host, and IPv6 support.
A prerequisite for using Darkstat is that it must be enabled on the Test Agents for which statistics are to be collected. You can then access the network statistics by connecting to the Test Agent through your web browser by pointing to the URL "http://<TA_ip>:667", where <TA_ip> is one of the IP addresses on the "eth0" interface of the Test Agent.
