This requires opCharts-4.5.8 or later.


It is possible to supply user-defined fields when editing a node, for example:

Note the new tab with title 'Extra-Fields' and inside that tab are two user-defined fields: 'Contact Person' and 'Customer ID' - these will be saved along with the node configuration data.

How To Enable

Extra fields are controlled using the Form Schema feature. Create a new schema file: /usr/local/opmojo/conf/form_schemas/admin_nodes.json  (adjust path to suit your installation location).

The content of the file should look something like this:

    "label": "Custom node fields",
    "description": "Edit in conf/form_schemas/admin_nodes.json",
    "component": ["node_admin"],
    "tags": ["node"],
    "schema": {
        "configuration.customerId": {
            "title": "Customer ID",
            "type": "Text"
        "": {
            "title": "Contact Person",
            "type": "Text"
        "configuration.service_level": {
            "title": "Service Level",
            "type": "Select",
            "options": ["Aluminium", "Steel", "Carbon_Fiber", "Titanium"]

Note that each field key must have prefix 'configuration.'

Refer to the documentation on the  Form Schema page for more information on available options: field types, field order, form validation etc.
