zabbix-weathermap

A program that creates a weathermap to be used as a background in zabbix maps.

Features

• Get the bandwidth data from Zabbix
• Auto-Generate JSON Configuration from Zabbix Maps
• Create & Upload image to Zabbix
• Support for straight or curved (bezier) links.

Caveats

• Zabbix's native link lines remain vissible. In order to 'fix' this you can use a custom adblock element filter: my.zabbix.domain.com##.map-links

Requirements

• Zabbix 6.0 (Lower versions were not checked)
• NodeJS V16.13.0 (Lower versions were not checked)
• PM2 or some other method to run NodeJS Continuously
• Zabbix account with API access

Installation

git clone https://github.com/metrotyranno/zabbix-weathermap.git
cd zabbix-weathermap
npm install
pm2 start . --name zabbix-weathermap

Configuration

Main Configuration

config.json

{
    "zabbix": {
        "url": "http://zabbix.company.com/zabbiz/api_jsonrpc.php",
        "user": "Admin",
        "password": "Password"
    },
    "updateInterval": "0 * * * * *" // Every minute
}

This configuration is fairly straight forward. Keep in mind that the protocol should be correct. If you use HTTPS, the API url should be HTTPS too.

Map Configuration

The map configuration file is automatically generated on every run. It is created in a disabled state.

    "name": "MAP NAME",
    "enabled": false,       //Set to true to draw / update the background image with a weathermap
    "colorMap": [           // The color map is used to convert the link utilization % to a color to draw with.

TODO's

• Include a legend / generation time
• Create a graphical interface to modify the JSON configuration. Particularly useful for finding / setting the source items & playing with the curves.
• Create a release with nodeJS embedded running as a service
• Clean up code
• Overall error detection & handeling, simple crashes / hangs now
• ?
