Summary

An application framework with built-in drivers (Controllers), data holders (Sources) and config parsers (Rules). Also includes a web interface for configuration and troubleshooting.

Features

  • Abstract base classes for creating custom controllers, sources and rules

  • The configuration is done using configparser with extended interpolation

  • Start a new netdef project with cookiecutter or make-project. Templates available at https://bitbucket.org/fholmer/cookiecutter-netdef.

  • Built-in Controllers:

    • OpcUa server / client (freeopcua)

    • TcpModbus server / client (pymodbus)

    • icmp ping / url ping

    • XmlRpc client

    • trigger events by using crontab format (crontab)

    • disk, memory and CPU monitoring (psutil)

    • MQTT client (using a simple messaging format called DataAccess) (paho-mqtt)

    • Simple RESTJson client

  • Built-in Rules:

    • Generic CSV config parser

    • Generic INI config parser

    • Generic Yaml config parser

  • Built-in application engines:

    • threaded engine with stdout/stderr only

    • threaded engine with web-interface (webadmin)

    • serve webadmin behind nginx reverse proxy

Use Cases

Netdef is useful if you want to create a middleware that can translate a protocol into a completely different protocol or data format into a completely different data format.

Getting started

First install make-project:

$ python3 -m pip --user install make
