10. Visualize monitoring measurements
While monitoring ReaderService
™ will periodically perform a read operation and then send the
results to the Message Queue and internal database.
The latest results in the internal database can be seen on the
data
page. The interactive graph
displays one sensor measurement from a single tag (by EPC) at a time.
11. Stream data through the Message Queue
The sensor results are also available for real-time processing through the MQTT interface. To
receive the data, follow these steps:
1.
Install an MQTT Client or demo application such as MQTT.fx
2.
Connect to the MQTT Broker using the reader’s IP address and default port of 1883
3.
Subscribe to the topic
axzon-topic
using a QoS of 2
4.
Wait for a monitor cycle to complete to receive the message(s) containing sensor data
