Starting and stopping a telemetry channel
A telemetry channel is automatically started when it is created. It stops when the queue manager or MQXR service is stopped. We can also start and stop a telemetry channel manually.
A telemetry channel also stops when it is purged. Purging a telemetry channel disconnects all the MQTT clients connect to it, cleans up the state of the MQTT clients, and stops the telemetry channel. Cleaning the state of a client involves deleting all the pending publications, and removing all the subscriptions from the client.
Before you begin
Ensure that the MQXR service is defined and running.
Procedure
Start or stop a telemetry channel manually, by performing the following steps:
- In the Navigator view, expand the Telemetry folder.
- Click Channels.
- In the Content view, select the telemetry channel you want to start or stop.
- Right-click the selected telemetry channel, then click Start or Stop.
Results
The telemetry channel starts or stops depending on what action you performed. Note: To purge a telemetry channel, right-click the selected channel and click Purge.
