Naemon Event Broker Module written in Zig

This is a PoC to demonstrate that it is relatively simple to use the Zig Programming Language to develop a custom Event Broker Module for Naemon

Setup Zig on Ubuntu

Download latest version from https://ziglang.org/download/

wget https://ziglang.org/download/0.11.0/zig-linux-x86_64-0.11.0.tar.xz
tar xfv zig-linux-x86_64-0.11.0.tar.xz
mv zig-linux-x86_64-0.11.0 /usr/local/zig

Add zig to $PATH

export PATH=$PATH:/usr/local/zig

To have zig permanently available, add it to /etc/environment like so

":/usr/local/zig"

Install Naemon Build Dependencies

A event broker module get's loaded into the Naemon Core. For this reason a running instance of Naemon is required. This repository contains everything you need to get started!

Fedora

sudo dnf group install "Development Tools"
sudo dnf install git glib2-devel help2man gperf gcc gcc-c++ gdb cmake3 pkgconfig automake autoconf nagios-plugins-all libtool perl-Test-Simple

sudo ln -s /usr/lib64/nagios /usr/lib/nagios

Ubuntu

sudo apt-get install git build-essential automake gperf gcc g++ gdb cmake help2man libtool libglib2.0-dev pkg-config libtest-simple-perl monitoring-plugins

VS Code

It is recommended to use Visual Studio Code as IDE so you do not have to deal with setting up Naemon Core or a Debugger by yourself. This repository contains pre-defined configuration files for VS Code. Of course you can go with any editor you like.

First, run ext install webfreak.debug in Visual Studio Code. Press ctrl + p, paste the command and press return

Start development

From the main menu of Visual Studio Code select Terminal -> Run Task... and pick the initial task. This task will automatically do the following things for you:

• Clone the master branch of the official https://github.com/naemon/naemon-core/ repository
• Build Naemon core from source
• Create the Naemon default configuration
• Load the zig broker module into naemon

Now you are ready to start development

Debugger

For debugging, please make sure you have the Zig Language and (C/C++ for Visual Studio Code)[https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools] extension installed. Also make sure to install the Zig Language Server by pressing ctrl + p and type: >Zig Language Server: Install Server

You can now debug the Zig code

And also the Naemon Code if required
