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.

a Mozzo is Neapolitan for a young helper who does menial tasks on a ship and is quick to acknowledge things.

cd mozzo
chmod +x mozzo.py
./mozzo.py --help

Option 3: Install via Pypi

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 should have 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"
