OpAMP Config Catalog UI

Overview

The provider can host a Config Catalog page that indexes configuration files from configured folders and displays metadata extracted from top comment blocks.

• UI route: /catalog (default)
• Help route: /catalog/help (default)
• Data route: /catalog/api/files (default)

The page is added to the provider feature menu when enabled.

When the catalog is hosted inside the provider, the header also includes:

• Server Console to return directly to /ui
• Back to trigger browser-history navigation when a previous page exists

Those buttons stay hidden in standalone catalog deployments.

Configuration

Configure in opamp.json under top-level opamp.config_catalog:

{
  "opamp": {
    "config_catalog": {
      "enabled": true,
      "menu_label": "Config Catalog",
      "route_path": "/catalog",
      "help_path": "/catalog/help",
      "ui_base_css_path": "/config-service/ui/assets/config_ui.css",
      "sources": [
        {
          "folder": "config-service/json-definitions",
          "extensions": [".json", ".yaml", ".yml", ".conf"]
        }
      ]
    }
  }
}

Fields

• enabled: enables/disables the feature.
• menu_label: label used in provider feature dropdown.
• route_path: base UI route.
• help_path: route for catalog help content.
• ui_base_css_path: CSS path used to align appearance with config-service.
• sources: folders and extension filters to scan.

Header Metadata Format

The catalog parser extracts metadata from top comment lines using:

• config-service: key=value

Example:

# config-service: config_type=fluentbit
# config-service: version=5.0.4
# config-service: config_version=release-27

All discovered keys become table columns.

Provider UI Feature Menu Integration

Provider feature dropdown entries are configuration-driven from component-entry-points.quart entries that include label and url.

Example:

{
  "component-entry-points": {
    "quart": [
      {
        "entry_point": "config_service.opamp_integration:register_config_service_feature",
        "label": "Config Editor",
        "url": "/config-service/ui",
        "enabled": true
      }
    ]
  }
}

Help

Catalog help page:

• /catalog/help

Selection Checkbox Direction

The catalog selection checkbox capability remains available as part of normal catalog use rather than being hidden behind a separate mode toggle.

• The fixed first column shows a checkbox for each catalog row.
• The matching column filter supports Both, Selected, and Unselected.
• Clicking the checkbox updates selection state without changing the existing row-click behavior for viewing or opening a configuration file.
• The same checkbox workflow can later support ordered file-selection callbacks when those provider integration flows are enabled.
• This direction should not prevent the catalog from running standalone, and it should not create a dependency for provider deployments that do not enable the catalog feature.

Callback Apply Flow

When the catalog is opened with a selection_callback query parameter:

• an Apply button is shown at the bottom-right of the catalog page
• the selected files are posted back to that callback in the order their checkboxes were chosen
• the callback can normalize the list before returning it to the opening server console window
• on success, the catalog popup closes

The checkbox column is still present when no callback is supplied, so standalone catalog browsing and selection-based filtering continue to work without any provider dependency.
