DevOps Demo Agent

This is a sample showing how to onboard an agent and upload data (data points, events, files).

The demo is based on the starter code generated by the mindconnect-nodejs library and uses this library for connectivity.


It's required to create two assets in the MindSphere Asset Manager with the same configuration as the sample in mindconnect-nodejs for this to work:

AspectType 'Environment'
    'Humidity'    INT    %
    'Pressure'    DOUBLE kPA
    'Temperature' DOUBLE ºC

AspectType 'Vibration'
    'Acceleration' DOUBLE mm/s^2
    'Displacement' DOUBLE mm
    'Frequency'    DOUBLE Hz
    'Velocity'     DOUBLE mm/s

AssetType 'TestAssetType'
    'EnvironmentData': Type 'Environment'
    'VibrationData': Type 'Vibration'

Asset 'TestAsset'
  Type: 'TestAssetType'

Asset 'TestAgent'
  Type: 'MindConnect Lib'
  • The first Asset is the actual instantiation of the defined Aspects + Aspect Types, the type will be whatever Asset Type you defined earlier in the Asset Manager
  • The second Asset is the Agent, and must be of type core.mclib. We need to define all the Aspects again in the agent, and then need to map them to the actual values in the first Asset
  1. Create the Aspect Types with their Variables
  2. Create an Asset Type that references the Aspect Types you created earlier
  3. Create the first Asset with type the Asset Type created earlier
  4. Create the second Asset (the Agent) with type MindConnect Lib:
    • Choose a security profile and generate the onboarding key json
    • Copy the key data, you'll need it later for the agentconfig.json file
  5. Configure the Agent:
    • In the Configuration tab, creating a Data Source for each of the Aspect Types instantiated earlier, adding inside Data Points matching each of the Variables of the Aspect Type (the name can be chosen freely, but the Data Type and Unit must match)
    • Then in the Data mappings tab, link each of the variables (Data Points) to the Aspects of the Asset. You'll have to click the Link variable link and then search for the Asset. Please note that you will only be able to link Data Points that are compatible (type and units match)

After this you will have an Agent linked to the Asset, and you will be able to deliver data points to the Asset via the Agent.

How to run

  1. Install the dependencies
    yarn install
  2. Download the initial JSON token of your agent and save it as agentconfig.json. If you prefer to do this manually, you can use agentconfig.sample.json as a template
  3. Copy the file assetmanager.sample.json to assetmanager.json and adapt the identifiers of the Asset and the Data Points. You can find them in the Asset and Agent configurations of the MindSphere Asset Manager
  4. Run the code. The script will perform the agent onboarding and upload timeseries data, create an event and upload a file
    yarn start
  5. Now you can go to the MindSphere Fleet Manager to view the uploaded data


The timeseries data in MindSphere can be assigned to either the Agent or the Assets. There's use cases in which it is useful to map from a single agent to one or multiple assets, e.g. when you have an environment temperature sensor data and you want to assign that timeseries data to all the assets which are in the room.

The files and the events don't require mappings and they can be assigned directly to the assets.

It is in most cases the best option to keep everything in the actual Asset and not to upload any data to the Agent. The Agent has other interesting data though, like the Online Status


  • Perform the Agent onboarding automatically via API calls to the Agent Management Service
You can’t perform that action at this time.
