Quick Start 1: Hello Engine
APPROXIMATELY 6 MINUTES TO COMPLETE
To understand how the engine operates, you want to monitor the raw data and specifically watch for erratic behaviors in that data. When you have a sense for the typical sensor data for the engines, you can identify and track unexpected data fluctuations which may indicate or lead to real issues.
Monitoring Bearing Temperature
For this Quick Start, you want to monitor the bearing temperature for each engine cylinder. While monitoring, you’re getting a sense for “normal” range and looking for spikes/fluctuations. The fewer fluctuations in bearing temperature, the “healthier” the engine and better and longer it will be able to perform. You will also (visually) see how bearing temperatures across cylinders relate to each other.

- Browse to your AXON Predict instance, http://localhost. (NOTE: If you cannot browse localhost and/or there are errors browsing, you can try to troubleshoot them yourself using Troubleshooting tips, or peruse the Edge Developer Community Forum for helpful topics.)
- In the displayed login page, type admin for the user name and admin for the password, and click Sign In. You'll see the default, empty Realtime dashboard.
You are going to visualize your device data in your dashboard. You want to look at some of the raw data values for the devices. To do this, you first need to add a visualization component to the dashboard.
- Click the Add a Visualization button.
- From the displayed VIEWS list, select the Multi Sensor component and drag it to the workspace to create your default layout.
Now you will view the devices and data available in your AXON Predict instance and create device groups. (The simulator provides real-time data. The Quick Starts will be using components that rely on both real-time and historical data. You can save the simulated data as historical data by creating device groups which persist data.)
- Click DISCOVER DEVICES. The DATA SOURCES panel appears, showing the data defined in AXON Predict for the related devices (and organization). For example:
In this example, you can see three sensors for the Cylinder 1 device, which is part of System Organization. This is some of the data provided by the real-time data simulator.
Now, create two devices groups: one for all cylinder devices and one for Cylinder 3 only. Note that you will use these device groups in later Quick Starts also.
- Click Device Groups, then click New. The New Device Groups page appears. First you will create a device group containing all cylinder devices, using these steps:
- Click System Organization.
- Click Group by node.
- Drag the displayed node ID (UUID) to the workspace.
- Type a name for the device group, like allCylinders_group.
- Click Create.
- Now create a device group containing just the Cylinder 3 device group; follow the workflow shown in this screen markup (creating a device group named Cylinder3_group):
- In the DATA SOURCES list, click the Persist icon for each of your new device groups:
- Click Realtime to return to your dashboard and click Sensors to display the list of devices and sensors.
Now, you will add some data to display in the Multi Sensor component. For the Quick Start use case, you want to monitor the bearing temperature for all the devices. In addition, because Cylinder 3 and Cylinder 8 were recently serviced, you need to review their exhaust temperatures.
- Click Discover Devices, locate the BearingTemp sensor for Cylinder 1, and select and drag it to the Multi Sensor component.
- Repeat the previous step until the BearingTemp sensors for all 8 cylinder devices have been added to the Multi Sensor. As you add sensors to the component, you see the streaming sensor data.
- View the data in the Multi Sensor chart: point to a data stream and see the name and value for the sensor for that related time period:
You can also change how data is displayed, including modifying the time window for the chart. You can try this out for yourself.
See some of the window tools:
- Click the Add a Visualization button and, from the displayed VIEWS list, select Performance Explore and drag it to the workspace. You'll see the new Performance Explore component appear below the Multi Sensor component.
- Click DISCOVER DEVICES and select the following sensors and add them to the left side of Performance Explore:
- Cylinder 3: Bearing Temp
- Cylinder 3: Exhaust Temp
- Then add the following sensors to the right side of Performance Explore:
- Cylinder 8: Bearing Temp
- Cylinder 8: Exhaust Temp
- Set the time periods for both sides and review device performance. (You may not see data in the component until you select a time period).
You can view data from different time periods. For example, you may want to look at the last hour of data for both devices, and then zoom in on the last 5 minutes of data.As you look at different time periods, the component will look similar to this: In this image, the legend for the component is shown.
- View the data on each side of Performance Explore, comparing the data from Cylinder 3 and Cylinder 8.
As a last step in the Quick Start, you will save the dashboard so you can reuse it later.
- Click the Dashboard Options button and select Save Dashboard from the drop down list.
- In the displayed Save Dashboard page, type a name for your dashboard and click Save.
Quick Start 1 is complete!
This Quick Start was intended to show you how your devices and device data appear in the UI and how you can view (historical) device data in dashboard components.
In Quick Start 2, you will learn how to perform mathematical calculations with your device data, through the development and visualization of simple compute questions.
Important – Make sure you have completed Quick Start 1 before starting Quick Start 2.
