Smdn.Net.MuninNode 1.3.0

Smdn.Net.MuninNode 1.3.0

A .NET implementation of Munin-Node and Munin-Plugin.

This library provides Munin-Node implementation for .NET, which enables to you to create custom Munin-Node using the .NET languages and libraries.

This library also provides abstraction APIs for implementing Munin-Plugin. By using Munin-Plugin APIs in combination with the Munin-Node implementation, you can implement the function of collecting various kind of telemetry data using Munin, with .NET.
