Custom Themes#

With this plugin you can define a custom theme for the Management Center, including a custom logo. You find the settings for your themes in the "config.json" file under "themes".

It looks a little like this:

"themes": [
"id": "custom",
"name": "Cedalo AG",
"light": {
"logo": { }}}]

Exchange current wordings, logos, colors by replacing the default values. The image files for the logo are encoded in base64.


An easy way to encode your own images is via base64 image.


With this plugin you can access several components of the Management Center via REST API, e.g., the topic tree information.

Topic tree information:

GET {base-url}/api/system/topictree
DELETE {base-url}/api/system/topictree

Broker Status:

GET {base-url}/api/connections
GET {base-url}/api/system/status
