Monitoring Remote Patient EKG Readings with MQTT

Instructions for this exercise are available on GettingStartedHealth.InterSystems.com.

In this exercise, you will use the interoperability tools built into InterSystems IRIS for Health™ to construct a basic user portal that monitors live EKG readings from a set of remote patients. See how you can use a minimal amount of code to quickly take real-time data coming from an MQTT broker, then save and display it on a dashboard.

If you would like to skip the exercise and view the completed application on your instance, navigate to Interoperability > List > Productions in the Management Portal, select Solution.MQTT, and click Open.

In the Production Configuration window, click Start.

Step 1: Installation

InterSystems IRIS for Health Sandbox

1. Change the directory: cd /home/project/shared
2. Type git clone https://github.com/intersystems/Samples-MQTT-EKG-Devices
3. Open the web terminal by navigating to InterSystems > Web Terminal and enter the login credentials provided with your sandbox.
4. At the next three command prompts, type:
   • set $Namespace = "INTEROP"
   • do $system.OBJ.Load("/home/project/shared/Samples-MQTT-EKG-Devices/Installer.cls","ck")
   • do ##class(App.Installer).InitializeLearningLab()
5. Store the topic string outputted from this process for later use.
6. Click the Management Portal link in your sandbox.
7. Change namespace to INTEROP

Docker

1. Type git clone https://github.com/intersystems/Samples-MQTT-EKG-Devices
2. Change the directory: cd Samples-MQTT-EKG-Devices
3. In the command line, type docker-compose up -d
4. Once complete, type docker-compose exec iris iris session iris -U %SYS "##class(App.Installer).InitializeDocker()"
   • NOTE: If you have already allocated port 52773, choose an available port and update the docker-compose.yml file as well as the management portal link.
5. Store the topic string outputted from this process for later use.
6. Throughout the exercise, use the following connection settings: • Username: SuperUser • Password: SYS • Host: localhost • Port: 52773 • Management Portal URL: http://localhost:52773/csp/sys/UtilHome.csp
