About

Mozzo interacts with Nagios Core (4.x) via cmd.cgi and statusjson.cgi using standard HTTPS requests. It allows you to acknowledge alerts, schedule downtime, and view statuses without needing to install specialized Nagios libraries or scrape HTML.

Installation

Option 1: Run from source (Standalone)

You can clone the repository and run the script directly:

git clone https://github.com/sadsfae/mozzo.git
cd mozzo
chmod +x mozzo.py
./mozzo.py --help

Option 2: Install via pip

Install globally or in a virtual environment to make the mozzo command available anywhere:

git clone https://github.com/sadsfae/mozzo.git
cd mozzo
pip install .
mozzo --help

Option 3: Install via Pypi

python -m venv mozzo
. !$/bin/activate
pip install mozzo

Configuration

Mozzo requires a configuration file named config.yml. It will search for this file in the following order:

1. ~/.config/mozzo/config.yml
2. ./config.yml (Current directory)
3. /etc/mozzo/config.yml

[!TIP] Copy the example config.yml and edit it first.

mkdir -p ~/.config/mozzo
curl -s -o ~/.config/mozzo/config.yml https://raw.githubusercontent.com/sadsfae/mozzo/refs/heads/main/config.yml
vim ~/.config/mozzo/config.yml

Your config.yml needs the following structure:

nagios_server: https://nagios.example.com
nagios_cgi_path: /nagios/cgi-bin
nagios_username: nagiosadmin
nagios_password: mysecurepassword
default_downtime: 120 # in minutes
verify_ssl: false
date_format: "%m-%d-%Y %H:%M:%S"

Usage

[!IMPORTANT] You can run mozzo (if installed) or ./mozzo.py or python mozzo.py (if running from source).
