Netflow Monitor Plugin 0.1.0

Introduce

Netflow Monitor Plugin( or extension) is a dynamic library for interface traffic monitor along with Netis Packet Agent. It based on fprobe and can support Netflow V1/5/7 protocols.

Getting Started

Build

cd ./packet-agent-netflow-plugin/
mkdir build
cd build
cmake ../
make -j 4
# Then the libmonitor_netflow.so binary will be generated at "./packet-agent-netflow-plugin/".

Usage Explanation and Example

# The traffic monitor extension's configuration field explanations:
# ext_file_path(mandatory): .so file with absolute path, or relative path from pwd. This field is mandatory.
# ext_params(mandatory): the configuration for particular extension(plugin or dynamic library). Any field in ext_params can be absent for default config(false / 0).
#     collectors_ipport(mandatory): the list of collectors. 
#         ip: collector ip.
#         port: netflow packet send port.
#     netflow_version: (optional, default=5) Netflow protocol version. Now only support v1/5/7.


# Examples: 
#  - these examples list all available field.
