Netis Cloud probe(Packet Agent, name used before) is an open source project to deal with such situation: it captures packets on Machine A but has to use them on Machine B. This case is very common when you try to monitor network traffic in the LAN but the infrastructure is incapable, for example
There is neither TAP nor SPAN device in a physical environment. The Virtual Switch Flow Table does not support SPAN function in a virtualization environment. Also, this project aims at developing a suite of low cost but high efficiency tools to survive the challenge above.
pktminerg is the very first one, which makes you easily capture packets from an NIC interface, encapsulate them with GRE(other tunnel protocols are going to be supported later) and send them to a remote machine for monitoring and analysis.
Besides, 3 useful tools are also provided.
pcapcompare is a utility for comparing 2 different pcap files.
gredump is used for capturing GRE packet with filter, and save them to pcap file.
gredemo is a demo app which is used to read packet from a pcap file and send them all to remote NIC. This can be only used when built from source code.
ProbeDaemon is a new added module from v0.7.0, which is responsible for the management of the pktminerg process. It can pull and kill pktminerg process and set the parameters of pktminerg in the command line. This module should work with CPM (Cloud Probe Manager)，which provides a user interface to set the strategies of pktminerg and can also display the statistis reported from pktminerg in graphs. You can contact Netis for the further support of CPM, or you can also develop your CPM.
