Service Discovery Configuration

Getting an Azure IoT Hub Connector Up and Running > Step 6. Configure the Connector > Configuration Properties Reference > Service Discovery Configuration

Service discovery enables the Azure IoT Hub Connector to find the ThingWorx Platform hosts and ports in a ThingWorx High Availability Clustering environment. Further, it enables the Connector to react to start and stop events for the platform instances.

The discovery group in the configuration file of a Connector provides the following properties:

Property Name	Required?	Description
cx-server.discovery.connectionString	Yes	A comma-separated list of ZooKeeper hosts and ports that the Connector should connect to for service discovery. For example: “zookeeper1:2181,zookeeper2:2181,zookeeper3:2181” .
cx-server.discovery.basePath	No	The default value is "/services".
cx-server.discovery.sasl-enabled	No	Whether Simple Authentication and Security Layer (SASL) authentication is enabled between the Azure IoT Hub Connector and ZooKeeper. To enable Simple Authentication Security Layer (SASL), set this property to true. To disable it, set the property to false. For information about SASL refer to the Installing and Configuring ZooKeeper for ThingWorx HA.
cx-server.discovery.sasl.krb5-conf.file	Yes if sasl-enabled is true. No otherwise.	If SASL is enabled, specify the full path to the configuration file for Kerberos, which is used for authenticating users with ZooKeeper.
cx-server.discovery.sasl-jaas-file	Yes if sasl-enabled is true. No otherwise.	If SASL is enabled, specify the path to the Java Authentication and Authorization Service (JAAS) configuration file for SASL authentication.
