Telemetry applications

Write telemetry applications using WebSphere® MQ or WebSphere Message Broker message flows.

Use JMS, MQI, or other WebSphere MQ programming interfaces to program telemetry applications in WebSphere MQ.

The telemetry (MQXR) service converts between MQTT v3 messages and WebSphere MQ messages. It creates subscriptions and publications on behalf of MQTT clients, and forwards publications to MQTT clients. A publication is the payload of an MQTT v3 message. The payload comprises message headers and a byte array in jms-bytes format. The telemetry server maps the headers between an MQTT v3 message and a WebSphere MQ message; see Integration of WebSphere MQ Telemetry with queue managers.

Use the Publication, MQInput, and JMSInput nodes to send and receive publications between WebSphere Message Broker and MQTT clients.

Using message flows you can integrate telemetry with Web sites using HTTP, and with other applications using WebSphere MQ and WebSphere Adapters.

WebSphere MQ Telemetry replaces the SCADA nodes in WebSphere Message Broker version 7. See Migration of telemetry applications from using WebSphere Message Broker version 6 to use IBM® WebSphere MQ Telemetry and WebSphere Message Broker version 7.0 for information about how to migrate version 6 WebSphere Message Broker message flows using the SCADAInput and SCADAOutput nodes to version 7.
